Mercury 1.0L 4 Cyl. 60 HP Conversion (See description for full details)
HTML-код
- Опубликовано: 12 сен 2024
- Welcome back as always,
Today we are taking a deep dive into the items necessary in order to complete a successful 40/50 HP to 60 HP conversion on a #mercurymarine and going over their respective locations. This conversion can be done successfully on both engines AS LONG as they are 4 cylinder 995cc engines. This mod cannot be done to the smaller 3 cylinder 40 HP engines.
Items required to complete a successful 60 HP conversion free of issues:
- 60 HP PCM new or used (used is preferred as it does not require intial PCM setup at a Mercury authorized dealer and is generally found much cheaper
- Restrictor ring removal
- Propeller change out of the OE Blackmax
Propeller pitch size will vary based upon what is required for your particular load and I HIGHLY recommend a stainless steel preferably of the Mercury brand in order to stay compliant within the specified RPM range of 5500-6000 RPM. I currently run 6100-6200 with my 4 blade Trophy Sport 10.625 x 14 pitch with zero issues, and no Guardian intervention, so you will be safe to be slightly higher. Bear in mind, a jackplated setup will increase RPM by about 100 - 150 RPM of whatever the propeller would spin nominally at WOT otherwise.
The 995cc #mercury powerhead is based off the 70 HP #yamaha powerhead and the F70 is specified to make its horsepower at 5800 RPM as per the Yamaha website, so I STRONGLY recommend you stay on the hot side over the lower side of the RPM powerband. Do not be afraid of high RPM. It is required to make power and to keep from lugging your lower gearbox and decreasing its overall service life.
For help sizing your prop, I would be happy to help if you do not know what to do, feel free to drop me a comment and we'll go from there.
I will need your CURRENT:
- Max RPM at wide open throttle
- Max speed at wide open throttle
- Current prop pitch
IMPORTANT SIDENOTE: The 40 HP 4 cylinder version model Mercury outboards come equipped standard with a 2.33:1 Command Thrust PCM. I did not realize this at the time of making this video so the requirements for your engine change. In order to successfully complete this conversion, you will need to obtain a 60 HP Command Thrusts/ Bigfoot variant PCM. Propeller pitch will also vary from what is shown in this video!
Extras:
I did not discuss this in the video, and it is optional, but for those running Champion copper spark plugs, I recommend NGK part number: BPR6EIX/ 6637 spark plugs for longest service life/ hottest spark/ easier ignitability for coils.

Thanks for the video, this is what got me researching everything I could find to convert my 50 HP (4 Stroke EFI) to a 60 HP and let me tell you there is a lot of misinformation out there. I found a brand new 60 HP ECU for a decent price, removed the restrictor and the difference was noticeable. Huge improvement! Brought my 16 1/2 ft Lowe fishing machine to life. Tested a few props and settled on a 14-pitch aluminum 3 blade. Gives me 38 mph @ 5980 RPM. The same 14 pitch without the mod would take minutes for the boat to plane. Still may try a few different props in the future. I would also like to comment on installing a brand new ECU for this engine. A lot of people say that dealer setup is required when they are brand new. I can 100% confirm this is false. No setup required. I installed directly on the engine and away I went, no issues, alarms, fault codes, nothing. Mercury Vesselview recognizes the ECU as a 60 HP and displays all information as it should including firmware version. The only issue with installing the new ECU is it will reset your hour meter to zero. I really don't mind that as I don't intend on selling this boat and I know what my previous hours were on my old ECU. Again, thank you very much, worth every penny to do this conversion. Cheers!
Get you a hydraulic 6" jackplate for it and you'll see a notable difference in both RPM and speed as well. You should gain 150 on the top end and you may even be able to turn a 14 pitch stainless Vengeance. Speed increase will be notable!
@@extremeboating7347 Oh crap! You got the wheels turning again! I'm actually thinking of going to a 4 blade 13 Pitch Mercury Spitfire Elite Aluminum for better holeshot. I've tried stainless in the past on these small motors and haven't had much luck. Dropped a lot of RPM and no significant gains. I am going to run with this for now but knowing how I roll I will be experimenting in no time! Thanks for all the legit education!
Thanks for posting this. My classic xl has the 50hp on it. I found a bargain ecu from a 60hp, that was being parted out because of damage, and removed the bushing, and changed prop. Better performance all around.
Now this is what I like to hear. I'm glad you are enjoying the mod and it has brought you a performance improvement across the board! Thanks for the feedback!
Great video here, very concise and detailed.
Im reminded of the days of the Yamaha 150-200 2 strokes, where we just changed a few things like the carb jetting and timing curve, along with different reeds. We also could shave the heads a bit to up the compression but that was usually too much cost and effort for the 4-6 hp difference it made.
On the newer Mercs, I did wonder if the cams are different for the 40/50 to the 60, that would be something a competent marine mechanic could do if it was worth the cost and effort, Happy Holidays!!
Happy holidays!
The 40 HP standard geared outboard is a 737CC engine and the 50/60 standard gearcase outboard is a 1.0L 995CC engine. They are two totally different blocks, but the command thrust lineup is the one that neuters the 1.0L down in order to accomplish the advertised horsepower rating. The CT/ Bigfoot series is the one that is more flexible as far as conversion capabilities are concerned.
I have a 2021 tracker V guide 16 . Im not spending a thousand dollars for a few hps However I did what every Nascar restrictor plate racer did. I DRILLED OUT THE HOLES IN THE RESTRICTOR PLATE UNTIL my ecu control picked up on the extra air then I sealed up the hole. I went from 32 mph to 35 mph with a much better hole shot. Im running a 4 blade 12 pitch. I added a lot of cupp to cut down on my RPM.
I do not know how long or how well that will work out for you. The 1.0L class and ECM70's that Mercury runs operate off a speed density style tune. They are not capable of compensating for the extra air you add by modifying or removing the restrictor. What you did introduced a lean condition and the PCM is not capable of compensating for that extra airflow by adding the extra fuel needed to make the air fuel ratio correct. If you haven't engaged Guardian mode already due to this condition you may soon. I'd be surprised if it didn't ever give you a problem either soon, or down the road.
Everything you said is correct. My service manual t though says 2008-2021 are same, with minor changes. I bet the Early year ECU would work too.
One thing to test out, is the cowling I think is restricted for air flow. Make a run middle of day with cowling record top speed rpm, then without shutting off motor make same run, do you see a difference?
I do for all my motors, theory is as motor hears up, it's sucking in water air and you lose a few rpm.
Bigger motors not an issue they have displacement to overcome it, the little ones 1.0l and below I've seen this.
Forgot to say make the 2nd run without the cowl, don't shut motor off or the ECU baselines new map/temp reading.
The only reason why the early year PCM would not work is because the connectors required to connect are two versus the one large one that the later PCM's take.
Running without the cowling might not be a bad idea just to see if there are any airflow changes. As the cowling on these motors do not have any openings to allow air through.
I anticipate that it likely wouldn't make a difference since the way these are tuned, they take into account for lack of open airflow in their fixed airflow density tune.
I'll give it a shot sometime anyway though, there's nothing to lose so why not?!
@@extremeboating7347 I did a test in my 40hp with and without hood, I was able to get 300rpm more, that made a difference. I just picked up a 60 to replace it.
Even gone as far as making ram air scoops for the hood for my f25 which I made videos on when it was brand new ruclips.net/video/U4GN4ZwRGpQ/видео.html
I'd be curious, if you can repeat my results. I'm going to make video of it in the new 60 here in few weeks.
@@omieyouknowme next time I take it out, I'll pull the hood off of it and see how it does. If the lack of airflow is indeed choking the engine down then an extra 300 RPM and a ram air style mod for the cowl would definitely warrant the need for re-pitching this prop to a 15P because I'm already running at 6100-6200 RPM on my 14P.
I just paid $170 to Mercury to extend my warrantee for the electronics for two more years. I'll have to wait another two years before upgrading my 2021 50 hp to a 60.
What electronics are we talking about here? The outboard electronics?
These mods are fully reversible and when done with care leave absolutely no trace of evidence that they were even touched. 😊👍
@@extremeboating7347 yes the outboard. The new factory warranty is 5 years but only 3 years for the engine electrical. They call it gold and platinum warranty levels.
Gotcha. Well the statement stands, but I entirely understand your hesitancy to do anything if you just got the extended warranty for the outboard.
Thanks for the video. I’m running a 2012 60 hp EFI already that have poor performance out of the hole, staying on plane and over reving. Can you confirm your prop diameter? Will going to stainles fix the over reving?
If I recall correctly it was 10 3/8" diameter prop. Going to the right pitch propeller will fix over revving, not switching to stainless.
Excellent video....thank you! Going to get my parts together.
Let me know when you want to buy the PCM. I got the connect on a guy who bought one in hopes of doing this mod for his 3 cylinder 40HP prior to confirming his was a 4 cyl. but (obviously) has no use for it.
@@extremeboating7347 Does he still have it? Thanks
He sold it already as far as I know. Check eBay and picclick. I would check picclick first as they tend to find things that ebay's search criteria does not otherwise locate.
Great video, thank you. I have a 2022 60hp Merc on a 18' bennington 188sv pontoon and my max speed is 17mph making it very difficult to get to my favorite fishing holes. I desperately need to go faster but the sticker on my boat says 60hp max. It appears your engine was a smaller than 60hp but you bought a 60hp computer chip. Will this work for me since I already have a 60hp? What prop would you recommend and how much difference would just a prop make (in mph) if I just changed the prop? Thanks again.
That really depends on what your top end RPM is. From the sounds of it you need to be A. Running a bigfoot/ Command thrust lower gearcase unit and B. A hotter prop. Do you know what pitch you currently run and what your wide open throttle RPM is? Unfortunately, you are topped out at 60 HP for your outboard, but there are other things we can do to make the most out of what you got.
Great video mate! Would this still work on a 2022 3 cylinder mercury 40hp?
If yes would the ecm need to be of the same year ?
Thanks
Has to be a 4 cylinder 40HP to work. (ie command thrust/ bigfoots only)
This is awesome!!! How do I get more info into this. I have a 2020 75 and was wanting to make it a 90 if possible. I just have no idea how to get started or where to research anything about it.
Unfortunately for you guys, the procedure is not as straight forward with the 2.1L engines as it is the 1.0L's. the 2.1L (yours) requires the PCM, the prop, and if I remember correctly a larger throttle body and the cam(s) in order to step it up in power. It's not a very straight forward thing and will definitely require you tear into the engine as well as obtain other more expensive parts in order to complete the conversion. I wish I had a better answer for you, but it is not as black and white for your class engine as it is ours.
Do your top speed is roughly 40ish? Does that hydrofoil make a difference? Whered you get that nice cover?
Yes. There is a video at the end that answers your question. 😃
As for the Cowl, the link is located at the bottom of the description.
The hydrofoil makes a difference of at least 1- 1.5 MPH, GPS speed confirmed. Without it I actually lose speed, stability, and smoother steering. Speed required to maintain plane drops from 22mph to 18 mph. I tried the boat with and without it back to back times consecutively just to make sure it wasn't placebo or it wasn't in my head and I was crazy.
Enjoyed your video!! I want to do this to mine. How do you find the part number for the 60 ecu. Does the year matter? Thanks
Thank you!
It really depends on what year you have. What year is your outboard?
Did you say that a factory new ECU would require setup at the dealer? Or is it a bolt in Part? Thanks
As of currently, supposedly it needs to be setup at a dealer. This was according to a dealer I spoke to prior to going with a used PCM at the time. If someone reading this or yourself manages to get a factory computer, brand new, and tosses it in, it would be a good idea to try it first and see what it does prior to taking it into the dealer for something it may not even need.
where did you get that motor cover ? Thats sweet
ruclips.net/video/qwGwXO2UZqk/видео.html
Great video. Would I be able to do this mod on a 2006 40hp Bigfoot motor? I'm also thinking of putting a jack plate on it. Is the same thing true on the older carburetor model's by being able to either rejet the carburetors or get a set of the carburetors, the reason I ask is I have a 2003 50hp 2 stroke on a pontoon I recently purchased.
Yes it is possible to do a carb swap on the older models absolutely. You need to make sure that the 50 is a 995cc or whatever is equivalent to the 60 HP engines of those years.
As for the 06 40 HP you need to make sure that it is a 995cc as well and that it is the same displacement as the 60 HP Bigfoot of that year, then you can do the restrictor ring removal/ PCM swap, and as a subsequent result of that extra airflow, run a much more aggressive prop tailored to the new HP output of the engine.
@@extremeboating7347 I will have to look into the 60hp Bigfoot but I know my 40hp Bigfoot is 995cc it has 4 cylinders instead of a 3 cylinder were my 50hp 2 stroke is the 3 cylinder model
Oh perfect, then the conversion should be doable!
@@extremeboating7347 Since my 40 is a Bigfoot would I have to get a 60 Bigfoot computer for it to work or would any 2006 995cc computer work? Thanks so much for all the info and help
You would need to get a 60 bigfoot computer exclusively. Not just any 60 HP PCM would work.
What propeller in stainless steel 4 blade you use. And my other question is the jack plate that you install between the motor and the transom help?
I use the Mercury Trophy Sport propeller, HOWEVER, I have since re-cupped and added PVS holes to my Mercury Vengeance 3 blade and it's performance abilities I kid you not are exactly on par in every category to the Trophy Sport now. Holeshot time? The same. Holding turn ability? The same. Steering? The same. Speed? The same AND faster than the four blade as well!
The jackplate helped, yes. It changed the dynamics of the way the boat performs entirely. Everything feels much smoother, peppier, and it allows me to get into SUPER skinny water without having to deal with getting jammed up in sand bars or unnecessarily weeded up now.
The mods aren't cheap, but the results obtained from them are 1000% worth it. It's a totally different boat compared to the way a standard Classic XL performs now.
I hope this helps!
Great video thanks! So are 40, 50, and 60hp motors does have same displacements? I'm new to these motors and currently working on a 60elpt big foot. Is it possible I can push it to the 90hp variant using these mods?
Two versions of the 40 HP exist and there is one of them which is 995cc like the 50 and 60 HP engines. The next class engine is a 2.1L which is the 75-115 HP class and you cannot boost the 60 ELPT CT/ Bigfoot to a 90 HP.
@@extremeboating7347 great info! Its really exciting to learn something new everyday about these motors. Thanks!
No problem! This is solely why my channel exists. I love to inform new owners like yourself and just general boaters. :)
Hi Sir,
First, let me congratulation for you video. I have a tracker boat 175 TF 2014. My boat have 3 batteries and 60 HP Mercury, gear 12 x 22, 1.83:1, Computer 8M0059304 and propeller splitfire 10.1 x 15P. I'm check the small cover red that you show in the video and my motor not have these cover. I'm try too the hydro foil sport SE400 but with this hydro foil I dont feel different. Right now my boat run between 34 to 35 mph. I know my boat can run more because this is my second propeller splitfire 10.1 x 15P and with the first one my boat run around 37. Why now run less fast I dont know. I'm replace my first splitfire because the first one was broken in the lake with a big sofa floating at same level of water. Any way any suggestion that you can bring for me I'm going to appreciate.
*Question: What propeller you use with you motor?
Best Regard
Antonio
Well, let's start simple. What's your current wide open throttle RPM, and what hole is the motor mounted on?
I run a Trophy Sport stainless steel 4 blade. If you used to run slower now than you did before, were you running 3 blade or were you always running 4? If nothing has changed in the Spitfire propeller you have been using and all you did was replace it, then it's possible you got a factory defective unit.
Also, what red cover are you talking about?
*the red cover is the ring of the intake, my motor not have this ring in the intake.
*I'm run 35 mph at 6,000 RPM. This speed is when I continuing moving my motor back until dont hold water.
*My motor base is resting complete in the limit of the transom so I cant lower more the motor.
*I'm going to write to whoever sold me the propeller to see if I can still change it.
@@antonioortega777 the red ring I had was because I had a de-tuned 60. It was a 50 HP version of it.
Your speed and RPM is in line with the speeds that 175's normally see. The Spitfire inherently drops speed due to the extra blade present that 4 blades over their 3 blade counterparts.
Where did you get your ecm? I can’t find it anywhere. Thanks for your help great video
I got mine from a Mercury outboard salvage yard in the Midwest if I recall. I can't remember their name, but you can also try Picclick, as they do deep search of eBay for items that are not represented well on their website. Type in "Mercury 60 HP PCM" or even ECM as a substitute. Worse comes to worse, there is always new which might be a little more expensive, but it's guaranteed to be in working condition.
@@extremeboating7347 I heard that if I buy a new one I can install it on my own it doesn’t need to be programmed
You can always install a new one on your own, I just do not know if initial set up is required at a dealer as Mercury PCMs may be different from your traditional one. You could always give it a try, you got nothing to lose!
What pitch prop are you running
Great video makes me wonder if I could do the same conversion with a 2018 75hp mercury to 115 hp would love to hear your thoughts?
It would require a PCM, throttle body change out, camshaft(s) and maybe even a power head swap out. There is more to the 115's than just a simple tuning change and restrictor removal unfortunately despite the fact the 75 HP and 115 HP use the same 2.1L engine block. Their conversion would be a bit more intricate that our 1.0L block outboard conversions.
Hi mate Gibo Brisbane Australia watching yr flushing vid this arvo was great just put a new 60 merc on my Quintrex hornet so no info from dealer apart from bookI'm not nieve but the book only showed a drawing for flush at teltail I use muffs but spent a lot on motor do I run engine when flushing at the teltail after using muffs I presume thermostat would still be open anyway great stuff u do
Hey there! If you follow the instructions like I did in my video, then there is no reason to run muffs if you're flushing at the tell tale. I also wouldn't run the engine while flushing at the tell tale. As long as you run the flushing sequence from bottom then top you're good to go. Obviously you want to use muffs down below and run the engine. Flushing at the thermostat port is always something I encourage if you want fully clean it out correctly. I hope this makes sense and I hope it helps.
Hi.. bro, Mercury Seapro can follow you advice ? Thanks
You may need something additional for Seapro versions, as those do not fall under the FourStroke lineup. My best advice is to ensure your motor falls under the specs of the 60 HP Seapro.
If you are unable to check that out yourself, I can do it for you, but you need to provide me with your engine information.
@@extremeboating7347 Mercury Seapro 60HP Sir.. Thanks again from Thailand. ;-)
What if you take the 60 hp and put the 60 hp R computer on it. You recon that would work
I see the computer specs are different than the 60. They resemble that to the equivalent of the ProXS series lineup computers which raise the revving RPM to 6300 which should offer a small boost in power. You CAN rev the RPM on the standard 60 PCM to 6300 without issue just so you know.
Thanks for the info..
Very interesting. What happens if you simply remove the restrictor ring? I have a 2006 50hp 4 stroke that's running fine but would like that extra horsepower if it's not too costly. Has anyone tried this on the older models earlier than 2014?
The computer expects to see a certain amount of airflow, it is not capable of adjusting for more like a vehicles computer. If you remove the restrictor alone then you will throw a Guardian code and it will continue to do that until you correct the issue. You can still run it, but it won't let you run on the top end.
@@extremeboating7347 Thanks for responding. It makes sense what you say.
So, because I have an older model, (2006) it turns out that many of the ECU are the same on the 50 hp and the 60 hp. According to my local marine mechanic up in here in Georgian Bay, you can check the serial number on the motor and the ECU and see if this is the case for your model. In my case it was. So, I simply removed the restrictor and have been cruising with and extra 400 rpm and an additional 4 mph. Thus I was able to simply remove the restrictor and with no issues whatsoever. My engine is on a 17 foot restored 1970s solid weld aluminum boat so the engine was a little undersized at 50hp and I only toped out at 31 mph and 5700 rpm. Now with the restrictor removed, I'm getting a better hole shot and it's far more responsive and I'm hitting 6200 rpm and 35 mph which is fast enough for me on the big waters of the Great Lakes. Perhaps those with older models are able to do this as well.
It would be cool if I could pin this to the top of the comment section but YT won't let me do that for some reason. I hope whoever goes into the comment section with an older motor sees this! Good tip from you Brian!
After reading this I just pulled the restriicter ring and took a test trip in my Boston Whaler Dauntless 13 with a 4-cyl 2005 50 HP. Revs we’re limited to 4800 rpm. I’m waiting for an ECM from a 60 hp 2006 to arrive from eBay. Stay “tuned.” for results.
I have a 2001 tracker 175, 75 elpto 2 stroke. Thought mine had the same hull as the new 175s, however it is a few inches shorter, & a few more narrow. Anyway, I know our boats are different. This being said, you seam to know about increasing Hp & props. Mine runs 41mph with stock aluminum prop. My 75hp 2 stroke is the same motor as the 90hp2 stroke, other than the carbs & prop. Question is if I change to a 90hp. What prop do you recommend? Also max hp is a 75hp, however 3 carbs will add zero weight & look no different. How fast do you think I will go. May add a manual jack plate also.
I don't have enough information to be able to get you an accurate recommendation and even then the right prop for someone else's boat may not work the same for yours due to hull age and condition, there are so many factors including motor height which comes into play in the speed factor.
If you do want to improve the output I always recommend a jackplate so your prop is not getting washed out by the hull due to motor proximity to the transom. Be aware that that may change the overall RPM output of the prop which if you are at the ragged edge with a new one will potentially put you over RPM.
As for the prop that you want to replace I need some more information to be able to give you a more accurate recommendation. I have your speed obviously, but I need current RPM as well as the current pitch that it is. The X factor here is going to be the fact that you will be increasing HP and so the RPM you will be at may put you over or under if we over pitch or under prop you.
If you can front the money for a hydro jackplate that will provide you with the most benefit on the fly due to your ability to change adjustability while you are running.
If you have other means of communication or social media, I'd love to tackle this with you actively. Let me know.
I have a 2018 mercury 40hp on a tracker heritage edition. Can i do these mods? Also which hydrofoil is that looking for a better whole shot and maybe top end. Right now I basically have to stay trimmed all the way down to stay on plane.
You should have no problem planning out with a 40 on a BTC Heritage with a 40. That motor is not the bigfoot CT so you cannot do the conversion on it unfortunately. How much weight are you normally carrying on your rig?
This work on a 2023 bass tracker classic xl?
Any tips on what prop I need? And will all the 60hp ECMs work?
Every rig is different so I can recommend you a 15 pitch Vengeance or a 14 pitch Trophy Plus (both stainless) but the jury is out if your hull was built like mine was.
As far as the PCM itself if you find a 60HP PCM that is single plug 2013 or 2014 and up it will work as Mercury is still using the same Motohawk ECM70 that they were in 2020. Nothing has changed as of current and I know that because my 2024 ProXS is using the same single plug PCM that the 50's and 60's do. If you buy a brand new one you will be good to go as well, just plug it in and go. The only thing it will do is reset your hours.
Which diameter for the prop?
The diameter is somewhat redundant as it varies from mfr to mfr. A lot of your pitch will also depend on whether or not you have a jackplate or not as that raises RPM as well so that may change the potential of you being able to run a larger pitch or not.
No jackplate for me.
@LSCHLEGS get one. It's a game changer without a doubt. Add some 2 degree transom wedges to the jackplate before you mount the motor 🤌 4- 4.5 second holeshot with a 3 blade. I have the two degree wedges left over from my Classic XL if you want them. Let me know if you do and we can work that out over email.
Nice GTO by the way. I used to own one and now have a Camaro ZL1.
Prop size recommendations for 13 Foot Whaler?
I wouldn't know. Need more information in order to help you out. Current RPM current speed and current prop size, unless you don't have those?
Where did you get the vented splash cover for the cowling?
Outboardcovers.com they make and ship it from Australia, however, so it would take a while to get to you, but they do a stellar job in their work as I'm sure you can tell.
Can this be done on a 2024 mercury 50hp? If so ,what years ecu is compatible?
I just answered this question 2 or 3 days ago so the following is a copy/ paste of what I wrote the other day:
Every rig is different so I can recommend you a 15 pitch Vengeance or a 14 pitch Trophy Plus (both stainless) but the jury is out if your hull was built like mine was.
If you find a 60HP PCM that is single plug 2013 or 2014 and up it will work as Mercury is still using the same Motohawk ECM70 that they were in 2020. Nothing has changed as of current and I know that because my 2024 ProXS is using the same single plug PCM that the 50's and 60's do. If you buy a brand new one you will be good to go as well, just plug it in and go. The only thing it will do is reset your hours.
Iam also running the Trophy sport propeller. At what height have you placed the engine in relation to your transom?
Second hole.
HOWEVER, big however, I can jack up my jackplate using the trophy sport prop as high as 2" additional while running at full blast. Giving me a dynamic prop to pad measurement of 2.875" and an extra 2 mph worth of speed.
@@extremeboating7347 any iusses with hole shot or ventilation in turns with lifted engine?
No. If you're too high though you will vent out badly.
What happens if I just remove the restrictor?
You get performance gains but it goes into guardian without warning above 5000 RPM most of the time. The PCM uses speed density tuning (fixed airflow) and is not capable of adjusting itself like a vehicle PCM is capable of doing.
Can i follow these same steps for a 3 cylinder 40/60 conversion?
I saw others mention changing out the carburator as well
That depends what year 40 you have. If you have the newest gen iteration 40 then you cannot. If you are carb'ed then you are good to go.
@@extremeboating7347 I believe it's a 2015. So there's no going up with this unit?
You would be correct. Unfortunately you are 100% locked in with what you currently have and cannot go up any further in horsepower.
Hi, Do you have a 2013 or newer ECM for a Mercury 60hp CT or Bigfoot available? If yes, how much are you asking? TY Chris
I don't sell them bud. That's not the function of this channel. I just give you the information you need in order to upgrade your rig. Try ebay or outboard salvage yards. The BF/ CT PCM is a little harder to come by over the standard EFI version, but if you look hard enough you'll find one.
@@extremeboating7347 The hunt for parts continues. Lol. TYTY
I have a 2007 40hp that I'm changing into a 60hp. When I took the boot off there was no restrictor plug in the air intake. Any thoughts as to why?
That 40 HP is probably sitting on a different engine block than the 50/60 engines so your 40 may be 737cc and the 50/60's are 1.0L. you may be topped out on power for your engine block size.
Question. I'm actually looking to go the other direction. Can you go from a 60 to a 40hp? I have a 2015 command thrust 60hp 4 stroke. I'm trying to keep my kids a little safer.
Great question! Yes you can actually. With that being said, however, you would need to grab a restrictor off a 40 HP version as it chokes down the throttle body opening to appropriately match the airflow that the 40 HP PCM is looking for. You would also need to prop down accordingly and you would also obviously need the PCM.
I have a 2020 mercury ct 40 looking to upgrade ecm to 60. We can trade if interested. Where are you located
I have a 2020 40 HP 4 cylinder Bigfoot. Do you know the correct partnumber of the 60 HP PCM? I think theres just 2 to choose 8M0168149 and 8M0168139 (which got an SP mark, so i think its for Seapro)
I checked into this before for someone else here on the comments section and if I recall correctly I think I landed on the first part number you listed. The 8M0168149. If it has an SP on it, don't get it.
@@extremeboating7347 Okay thanks! I have at the moment a Spitfire 11 rigged. On WOT (40HP) my RPM is around 5200. I wann go down to a 3 blade (with 60HP), do you have any recommandations for the pitch i should take? Maybe 13 or the 15?
The max RPM on that is 6000. You are hurting your engine by lugging it like that and need to decrease pitch. Is your outboard mounted on the correct hole? 5200 is really low by all accounts. The jump from 50 to 60 is a difference of 400 RPM so I can only assume a 20 HP difference will net you a 800 RPM difference all things being equal.
What kind of boat is this on?
@@extremeboating7347 Yes, the engine is on the right hole (bottom of boat is on the same level as the bottom anti-ventilation plate). The boat is like this one: mext-boote.com/index_htm_files/1931.jpg
It's 6,30m long, 2,20m wide and got around 700kg
Do you know if the 2.0L 80hp can be converted to 115hp by swapping the ecm? It is by my understanding the same engine. It is a 2022 model fyi
For that one I don't know about because those are usually overseas engines outside of the US.

Great video bro! Exactly what I've been looking for a while now ☺️ My outboard is an Mercury 100 HP EFI 2010 model. If I get this right, the 75 HP EFI all the way up to 115 HP EFI is the exact same engine; except models LOWER than 115 HP has an restrictor air inlet ring, different ECU programming and smaller prop?? I see that Mercury sell 4 different ECU's for the 115 HP EFI engine, so what is the difference and how do I know which one to purchase? Part number: 8M0083206, 8M0083210, 8M0083207 and 8M0083213. Since my model is 2010, is it posible to softflash the ECU through a special adapter cable => USB?
Thanks a lot in advance and best regards,

Something is off about the 100 HP that you have on yours. Is your model special? Like SeaPro, or something else? I haven't seen a model with straight 100 HP like that and I don't have enough information about that model to be able to tell you one way or another what you can or cannot do to it.
Yea the engine spec is straight "Mercury 100 HP EFI". I'm really sure that this engine is the exact same model as the 115 HP EFI (different programming, restrictor ring and smaller prop), why else should all models from 75 HP EFI up to 115 HP EFI be the same except the 100 HP EFI? In that case, it doesn't make any sense to me! Thank's again 🙋♂️
Too many variables to tell you. I see it on their parts catalog, but without knowing the size engine it is in cc's I really can't help you much. That is a model not offered here in North America.
I thought that if you put smart craft vessel view on your engine that it automatically transforms a 50 hp to 100 hp.
Before I go off on my tangent, there is NO way to convert a 50 to a 100. Smartcraft is just a form of diagnostics information via CANBUS protocol which is limited in the amount of information output it will display to you.
Mercury sucks. They don't let you do anything without paying exorbitant amounts of money. Tuning? "Nope." Upgrade? "Nope." "Oh you got money? Sure thing. That'll be $11,500 please. Thank you come again!"
My next engine will be a Yamaha or a Honda. At least they don't try and corporately bully or strongarm you into their will.
Thanks for the video. Do you know if 60 hp has a intake restrictor motor is lazy out of the hole.
No it does not. If you have a motor that is lazy out of the hole, you have an overprop issue, a motor height issue, or a transom angle issue. I can help you troubleshoot, but you will have to give me the year make and model rig you have, what hole the motor is mounted on, what pitch prop you have, and max RPM at wide open throttle you have as it is all relevant and important to optimizing performance out of the hole.
Also, how fast would you say your holeshot is, seconds wise?
I have a 2019 75hp merc. So specs for the 75/90/115 are identical motors. So if i get a different (115) ecm and remove restrictor ring and re prop im good ?. Parts catalog show a few didn't ecms for the 115. Does it matter which. Thanks for any help.
Do not try the mod. You will not run correctly at all despite doing the mod correctly and will probably throw all sorts of guardian alarms and codes. The 75 HP and 115 HP are two different animals entirely despite having the same power head. The 115 uses different camshafts and I believe may have larger valves than the 75 HP version. So despite sharing the same engine upper and lower blueprints, that's where it ends unless you are willing to pay for a new cylinder head off a 115 HP along with a new PCM and prop I would definitely not do it at all. Check the parts catalog for the PN of the cylinder head assembly and check to see if they have the same PN between the 75 and 115.
Now the 75 to 90 HP... that may be something worth looking into possibly.
The 115 is the same as the 135 and 150. Totally different than the 90
Hi
looking for upgrade of 50hp 2007
have ecm 0704 installed. but for the 60hp i can only find ecm 0401 available. anyone know if that will work?
Ive read on a few tracker forums that you can simply remove the restrictor plate and prop it without changing the ECM. Any feedback from people who have done this successfully? Wanting to do this on 2017 merc 50 running on a 2017 tracker Pro 170.
This may have been a thing on previous gen models using the Motorola 555 PCM with the dual plugs. These new gen PCM's, however, use a speed density tune where they are incapable of adjusting to new airflow or fueling changes if they are made (i.e additional airflow being provided by removing the restrictor ring). I tried removing the restrictor ring myself and running it initially, but would consistently get shut down by the guardian feature. It was only until after I replaced the PCM that it stopped cancelling my runs out.
Hi, are there problems getting dealers to setup a new unit for you?
Not that I know of. It's a pretty standard thing for them to set up new computers for all the new outboards that they get. So it's a fairly regular thing they do.
There is no setup. The ECU is plug & play.
Have you confirmed this already? If so this changes the game as far as buying new vs. used.
Hey. I have Mercury 50 efi four stroke 2006 year. Can I remove this plastic tube? I want to send a computer to increase the power up to 70 hp and also I want to change the prop. What do you think? Greetings
Hey man I got a 05 tracker with a 60 efi with champion ra8hc plugs. Should I be okay running the ngk plugs u specify? I saw that the cross to ngk online is DCPR7E - NGK Spark Plug, 3932. How did you find that thT plug is okay ?
Champion plugs are for 60's and 70's Chevy engines. Why they are being used in modern day EFI equipped engines is beyond me. Yeah man, that's the plug you want to use. They are awesome. Zero issues.
@extremeboating7347 so the ngk bpr6eix-6637. Knot the dcpr7e that ngk cross refrance for the ra8hc , also saw that some people run their motor on the second hole? Mine is on the 1st hole. I work at a mechanic shop, so lifting the motor would be a breeze. Thanks bro 👊🏻
@extremeboating7347 what did you gap the ngk plugs to ?
@chrisfitzsimmons5560 DCPR6EIX is the iridium version of the copper one. That's what you want if you want to go longer intervals between changes.
The second hole mounting is more for when you have a stainless prop as the aluminum won't grab as well and you will likely have a higher chance of blowout while under way and definitely while turning.
I already have a 60 Mercury will it also have a restrictor plate in it?
No sir. You are maxed out as a default.
Have you ran this setup without the Jack plate? If so, what speed were you getting out of it then?
Yeah I did actually. I was seeing about 1.5-2 mph less consistently.
@@extremeboating7347 what was your setup prior to putting the Jack plate on it? 60 conversion, 15 pitch vengence ss prop and cavitation plate?
@@kennethbolton5647 it was a standard 50 HP, Blackmax 14 pitch aluminum prop and, no hydrofoil or jack plate, copper spark plugs. Very basic setup.
The reason I ask, I've converted my engine and a friend had a 15 pitch black Max aluminum prop. I stuck it on there to be sure not to turn it to many rpm and it turns it well. Of course, with the direct mount on second hole from the top, I'm still gaining rpm but blowing out at around 5850 rpm running 35.6 gps.
@@kennethbolton5647 that's because aluminum props do not have the biting capabilities that stainless props do to the water, so when you run a 60 with an aluminum prop you HAVE to run it on the very top hole otherwise you will blow out like you are indicating despite being at an ideal RPM. So either bring your motor back down to the first hole if you want to keep the aluminum prop or go stainless if you want to be on the 2nd hole.
Did you convert because you watched my video or was this something you did on your own?
Can u mod a 2001 50 horse? I have it on same boat with a Jack and set back, No hydrofoil, 14 p 3 blade and get about 35
I'm not sure about that. You would have to know what kind of PCM it is first and then we can kind of go from there. I'm thinking it is the Motorola 555 style PCM, but I could be wrong.
Where did you get that motor cover ?

I have mercury 60 HP bought 2020. But RPM when full throttle only 3800. Speed of boat around 8-10 knots. Can you give me advice How to increase RPM to 4500-5000 RPM for boat can go faster
The RPM spec on these outboards are 5500 - 6000 RPM. You are way off on your operating speed. You are going to need to change out your propeller, you may also not be trimming properly.
So I can do this the 40hp on my 21' classic xl?
Your 40 is exempt from this mod because your 40 is a 747cc standalone engine and does not share engines with larger horsepower outboards.

Where did you get the motor cover?
Check the description. It's in there at the bottom.
I have a 2009 40 3 cylinder, would I be able to convert to a 60?
Most likely not. You would have to check the displacement on yours and compare it to the 60's of that year/generation.
Can you remove the air restrictor ring without upgrading the PCM?
Well yes you can. Should you? Absolutely not. The PCM is looking for a specific amount of airflow. By removing that ring you change the airflow the PCM wants to see and you'll piss off it off then it'll throw you into guardian mode at random. It'll happen more frequently in higher RPM ranges, but it can happen at any given point. Even at cruise.
@@extremeboating7347 its interesting they don't allow the ECU to increase fuel when it senses more airflow
Normally I'd say it is odd, yes, but these PCM's are tuned in Speed Density so it's not actually odd in any way at all. These are not like vehicle computers which have a wide range of compensations adjustments and strategies available within them to get the engine back into optimal running ranges. It is not designed to make airflow or fueling adjustments outside of its designed parameters. If at any point either are tampered with or modified at any given point it will throw guardian codes/ sound the alarm at the console/ and make every attempt it has designed within it to slow you down to prevent damage to the powerhead.
I bought a boat with a 2017 mercury 40 pro. As i looked in the engine i saw that he has already changed the mainboard to a 60hp version and has a vengeance prop.

A 50 on a 175? I would almost say you need to be down to a 12. Maybe even 11 pitch. It depends on if you have a stainless or not. I think 13 is going to be too much prop for your size rig.
Thanks for your help, I plan on doing the conversion in the future. I have heard ECU can be flashed,is that true and what company does it?
That used to be true. Now you have to replace the PCM to a 60 in order to get it's power. I got a video on it. Check my channel as it gives more info about the 60 conversion.
Where can you get the cumputer module? do you have part number for the 60?
There are various part numbers for the 60 PCM and all vary through the years despite all of them being the same with the exception of CT/ Bigfoot models. If there is any doubt, I recommend using the Mercury/Mariner parts catalog.
The PCM is obtainable either brand new via Mercury or Quicksilver brand (you have to get these initially set up at an authorized Mercury dealer, however) or you can buy them used via a salvage yard if you can locate one. I would check eBay as well. They pop up on there relatively regularly. You just have to ensure they are single plug models as there is a variant from earlier years which has two plugs. For one lucky person who doesn't want to do much searching at all, I have access to a used 60 HP computer and can reach out to my connection if someone or yourself wants to buy it from them for relatively cheap.
@@extremeboating7347 I would definitely be interested in talking with them and purchasing if it's available still.....

I’m new to this conversion stuff so don’t judge… I had a 2000 pro team 175 with a 40hp 3carb set up. At 5800 rpm had a top speed fully loaded at 28 mph. I recently had a 2014 60hp put on the back with a lot higher expectations for speed. At 5800 rpm wot my new top speed is 32 mph and is currently do so with a 13p prop. Do you feel this is an accurate speed for this boat type or is there more to be had out of the 60hp motor simply by changing the prop.
Thanks
One more thing… what do you feel is a same RPM to rev this particular motor to?
*Safe
Ouch. That's fairly low speed. Your motor is most likely buried or the prop pitch for it is not correct. What hole are you mounted at the transom and what pitch prop are you running on it?
There is another factor which comes into play here and that is the shape of your hull and/ or the age of the hull may not be allowing for good speed, that in which case there is nothing you can do about that. Does the bottom of your hull have any dents or issues with it at all?
You probably could gain another 3-4 mph, but I'd have to know the answer to all of the questions above. You may very well be topped out due to your hull efficiency. It just depends what you got going on.
The prop says 13p on it and the motor is mounted all the way down.
The bottom of the boat is perfect aside from just needing some polishing but it’s never left in the water and has no dents
Hi is it possible to make this kind of conversion with a 2004 3cyl fourstroke efi 30hp to 40hp?

Unless you want to pay over $12,000 and STILL be limited to what you can do because you have to report to them any changes you made, unfortunately, no.
What this is, is corporate bullying at its finest and it pisses me off to no wits end. Needless to say, this is my first AND LAST Mercury outboard, because I refuse to be told what I can and cannot do to my boats outboard after already paying an exorbitant amount of overpriced money on it.
@@extremeboating7347 can you replace the ecu for like a megasquirt?

Nice man! Welcome to the club!
Do you want a 3 or 4 blade? If 3 blade stainless you can run a 15 pitch Vengeance. If 4 blade stainless the biggest you'll find unfortunately is a 14 pitch Trophy Sport, as Mercury discontinued their 15 pitch 4 blade Trophy Sport props. I had to get my 14 pitch modified to a 15 because it was slightly hot, but it's still not a true 15.
If you want to go aluminum then a 3 blade 16 pitch Blackmax works, if not you can get a Spitfire in 15 pitch, and that's the largest pitch size they have for them, but you may be slightly hot if you go with one of those.
Where can I find that engine cover?
That's not an engine cover. It's a cowl splash guard and I have a video on it. Search my channel and you'll find it.

Hi, I got the exact boat and engine. I did the conversion to 60hp and need to prop it correctly. I want to get a 4 blade. I'm thinking a 15 pitch but not sure if there is a trophy sport 15 pitch. Can you help?
The 15 pitch has been discontinued unfortunately. They only have the Trophy Sport 14 pitch but you can always buy the 14 and get it re- pitched to a 15.
That being said, a 14 may be suffice for you. Do you have a jackplate on it or is the motor directly attached to the transom?
@@extremeboating7347 I have a jackplate on it too.
Is it a hydraulic or is it manual?
@@extremeboating7347 it is a 4 inch hydraulic
Awesome! Okay so, ideally you would be better off with a 15 pitch Trophy Sport indeed and a dynamic prop to pad (PTP) of roughly 2.875", HOWEVER, you have a smaller setback than I do so I can't say that will be your final dynamic measurement for sure. Your static prop to pad prior to plane out should be about 5.625" (ie on the jackplate your motor should be mounted on the 2nd hole).
You will need to pick up a 14 pitch and prior to any hydraulic jack plate lift you should see an RPM of about 6150 - 6200 at WOT prior to any prop re- workings done. If you need recommendations on where to send it I'd be happy to refer you to the place that did my work.

Thank you so much for quick reply’s, you’re the man!
Will changing the ecu throw off the engine hours?
It may. I have not checked my hours on the new PCM. Nothing an hour meter won't solve mounted inside the engine compartment won't solve if you are worried about the hours.
@@extremeboating7347 I've ran the 50 on my pro 170 with out the restrictor just to see the difference and it's huge, until the guardian kicked in.. 60 ecu is on the way
@@jerrettlorton7437 yeah the engine will run without the 60 PCM after you take the restrictor out, but Guardian will definitely kick in by WOT due to the increase of airflow that the 50 HP computer sees as a "lean" condition from the airflow allowed without that restrictor being in that the computer cannot compensate for.
Do you what should to convert a mercury 90hp/100hp 4 strokes to a 115hp?
You may need to investigate if the head is different on the 90 like it is on the 75 HP 2.1L class because if it is it's not as easy as upping the HP and would require you perform a reflash on your current PCM in order to compensate for the lack of airflow (at least this is the case on the 75HP model). That cannot be done now due to Merc's cease and desist on all major tuners out there, so you would have to know someone who is capable of performing it. IF the head design and setup is the same on the 90/115 HP models, however, it would be as easy as removing the restrictor, replacing the PCM with a 115 HP version and then replacing your prop according to the RPM you need to be.
@@extremeboating7347old thread I know but the gearing on the 75 is lower than the 90 and 115 therefore needs a more aggressive prop than a factory 90 or 115 to control the rpm’s when the hp is upped. I’ve seen mid 20’s on the pitch
Oh you know what, you're right because I've seen 75's with flashed PCM's running the equivalent to 115 HP via the flash turning 24 pitch props whereas a 115 couldn't handle that.

It was my first prop on the engine actually. I would only see a max of 42.7 MPH very inconsistently and two times I saw 43.7 MPH. I wanted consistency, better holeshot and cruise so I opted for the one I have now. My 4 blade actually has more speed in it and I can go to a 15, but they don't exist in a 15 so I'll have to get it custom pitched, which I'm probably going to do here really soon.

Have you checked for fuel and spark to the engine? Also, when you turn the key to engine on position, do you get a solid beep from the ignition before the engine is on?
It has fuel and spark. It will run just fine if I put the 40 ecu back in. No beep on key with 60 ecu.
I hate to say it Chuck, but you got sold a bad PCM. The key beep is indicative of a total systems check, an audible "check engine light" if you will. If it doesn't do that, the engine will not start, and it doesn't matter how strong spark and fuel going into the engine is.
Do you know how to test if the ecu is bad?
There is no test to my knowledge, but I do know for certain that if a beep is not present at ignition to the on position, the PCM is HIGHLY suspect of being defective and a new/ different one should be tried.
Do you know what ecm model number I would need for a 2010 efi 50?
I do not know personally. That year outboard uses the previous gen 555 two plug PCM. It shouldn't be too hard to source one, but if you don't find anything I can always try to look for you.
@@extremeboating7347does it matter what year it is or as long as it’s the 2 plug it’ll work?
@@extremeboating7347like would an ecm from a 2006 work on a 2010?
As long as it is a 2 plug style Motorola 555 generation PCM you are good to go.
@@extremeboating7347what about 2 style plug and Motorola ecm0401?
Can you do this to a 2015
Absolutely!
Do you know if there actually is a restrictor ring in the 60hp efi? Is it not only in the 40 and 50 hp.
Yes I do, and no there is not. The 60's are the maxed out version of that engine block from the factory. There are no further power mods you can do to the 60 HP to make it be more powerful, however, depending on the rig you have, there are certain other things you can do to optimize the power the 60 delivers and really fine tune the overall performance of it to make it have really stellar holeshot times, and overall optimal utilization of HP it has.
What is the part number of that 3 blade vengeance you showed in the video and would that work on a 2019 50ph merc ?
No it wouldn't work. It's too much prop for the 50 HP. You would be over pitched and under revving it. Essentially lugging the engine.
Hows It going I have a 2013 Mercury 40hp 4 stroke. Does the year of PCM matter?
The year of the PCM does not matter as long as it is within your generation motor. The 2013's may be the cutoff year for the two plug PCM's. You'll have to physically look at yours to determine if it is, or if it is a 1 plug PCM.
You will also need to make sure that your 40 HP is a 995cc model and not a 747cc model because the smaller 747cc models are not upgradeable to a 50/60 HP.
Those ECM’s are not cheap..
They are like fruit. Sometimes you get a plentiful amount of them and so the cost declines. Sometimes you get a lack of, and when that is the case, the cost rises. Sort of like the used vehicle market.
Unfortunately, I know this video doesn't help the situation...
Salut je suis français ,j ai un semi rigide bombard 500 explorer avec un 50 CV efi de 2014 avec une helice black max pas de 12 ,vitesse max 58 km/h a 6000 tr/min ,j ai trouvé un ecm de 40 CV de 2021 neuf version Europe sur eBay pour 150€ que je vais faire reprogrammer en 60 a 65 CV en Italie pour 350€ ,me conseil tu de rester en 3 pales ou passer en 4 pales le bateau n'est pas une barque alu , et quel pas d helice d après toi
Super vidéo !!! Merci pour ta réponse
Hello! I'm sorry but I don't speak French and RUclips does not have an option to translate, so I have no way to help you.
@@extremeboating7347 mon anglais est pas bon mais j utilise Google Lens pour la traduction 😉
hello, I had an ecm box reprogrammed to 65 hp at a preparer in Italy, on my rib I get 37 mph at 6400 rpm with a black max 73134a45p12 propeller whether I am alone or with 2 adults and a child on board. sailing on a river I have not yet tried at sea, what advice can you give me on the step knowing I want to stay in 3 blades and lower the rpm a little and approach 40 mph thank you
From what I can see, that is a 12 pitch prop. You need at least a 14 pitch to bring you down to 5950-6000 RPM. You may even be able to get away with a 15 pitch
thank you for the info, a propeller pitch lowers how many rpm. knowing that on the Mercury configurator there are different propeller diameters for the 13/14/15
Has anyone used Megasquirt on these engines?
Some people have done full on aftermarket PCM retrofits but that requires a whole new engine harness as well.
@@extremeboating7347 Thanks for the reply.
What aftermarket management systems are they using?
I know little about these boat engines, but based on what I've personally done with MSEFI on a few cars and a motorcycle, you can more often than not use the factory wiring harness and sensors. You need to take a huge leap of faith and snip off the factory ECU plug and splice in the MSEFI plug, and as far as the sensors and injectors go, you just have to adjust the volt/resistance ranges of the sensors in the software so the MSEFI unit knows what it needs to see.
If it was originally a carbed engine, that's a whole other story, of course.
I can't remember what they use. I believe some have used GM hardware as a lot of the plugs and stuff used are based off of GM/ Bosch style connectors.
It's honestly a lot of work that is really not worth the results unless you are talking about a full on engine build involving replacement of cams by doing custom grind jobs and doing major porting of the cylinder heads/ stronger valve springs etc.
Even then, the amount of $$$ you are talking will add up quick, since there really isn't a huge market for power adders, especially on an engine this size.
@@extremeboating7347 GM stuff is cheap and plentiful and that's what most use on the car side of things, especially when they do a carb->EFI swap.
The main reason I asked about MSEFI is because I took a quick peek on eBay and the ECU you show us is $650, and I think a Microsquirt setup is about half that. It was just out of curiosity more than anything.
Re: engine build... That's a whole other ball of wax and unless the weight gain isn't acceptable, you know the logical answer- just get a bigger engine. That said, I think a TVS R410 would go quite well with that 1.0L Merc if one were motivated to blaze that trail.
@@Prototheria throwing on a TVS R410 would definitely require post tuning and that would be no easy task unless you had access to something like HP Tuners or a standalone EMS for sure. Even then, it would be difficult to gauge what sort of power you are making off of it unless you had access to some sort of outboard Dyno or hub adapter that you can bolt the prop shaft to in order to get a good reading off of it. Really this stuff just depends on how far you are willing to go with things and how deep your pocketbook is. Nothing is impossible with money.
As for the GM stuff, I would comb the forums because I know this stuff has been talked about and I have read about it firsthand. The thing for me was that I was just looking to make some cheap and quick pony power out of what I already had, and is an easy to do and perform swap for anyone else.
The other factor you have to consider which is a limiting factor is the size of the throttle body. It would become a bottleneck if you make power past 70 HP, as these are based off of the 70HP Yamaha powerhead.
Had a question hopefully you can answer. I have a 40 HP 2020 Merc. 4 stroke CT, I watched ur video on conversion to 60 Hp. I picked up used ECM from 2010, 60hp 4 stroke non CT. Should that work on my application. I'm now turning bout 5500 rpm @ bout 20 mph( full throttle)on back of 16' pontoon boat ? Like to get another 5+ mph?? Prop. Is huge cause is a CT thruster lower unit stock prop. 854342A33 14x10p. Any help can render is greatly appreciated. Ur videos R GREAT! Tyty
PS. This motor is the 1 litre, 4 cylinder model , everyone I asked says that power head is exactly same on all 40, 50,& 60hp 1 litre models & only thing different on CT model is a beefier lower unit, is true? & do you have any further contact info. Where might be able to contact you in person? Thank you again for all your help!
Your PCM needs to be a 2013 or newer, and since you have a CT the PCM needs to be specifically a CT/ BF computer with that label on it. Someone else just posted about this recently inquiring about it, they did the retrofit and it worked REALLY well. I would scan the comments and you'll find the part # you need.
Actually, it was in a different video that I made. Either way, I have the PN you need: 8M0114324
It may be difficult to find but when and if you do, I promise you it will be worth the trouble.
Additionally, you can always opt for a brand new PCM, but that route will be more expensive and require initial setup at an authorized Mercury dealer on top of the initial purchase.
If you need more help I'd be happy to check out the parts catalog for you if you wind up needing to go new, but I'll definitely need your serial # to do that. I also have other sources you can check for it as well. If traditional searches for it do not pan out. Let me know!
Hey there, preciate the response, sooo, the 2010 60 Hp ECM non CT , will definitely not work with my 2020 40 HP CT? & What would happen if I did hook it up? Would I burn anything up? Also do u have a source to any proper 60hp. ECM that would work for my 2020 yr motor? Don't need new. Would be interested in price &/or could trade + $ for prooer ECM if 2010 one I have for sure won't work. Any help or contact info You could render is GREATLY appreciated! By the way ur videos are fantastic & sincerely game changer's for me, as well as, I'm sure many people out there! Sincerely, much thanks Again!
A 2010 60 non CT would ABSOLUTELY not fit on a 2020. Even if you wanted to try and hook it up there is no way you could physically mate one giant plug into the two slots the PCM has.
I currently do not have any leads or sources for CT version PCM's outside of new. They are a bit harder to come by for some reason. I have some links to some places you can check, message me on IG, or on FB. My name on FB is Rob Boatin.
I appreciate the good words. Just trying to help out the community in the best way I can! 😊
Is there a difference with a 2017 40hp bigfoot?
Those are 995cc just like the 60 HP Bigfoot. Feel free to perform the mod!
Will this work for a 2004 40hp 3cyl 4stroke?
If it reads 995/996 cc it will but I don't think many of the 40HP models minus Bigfoot/ CT models will be eligible for this.
