How about all the reasons a boat could chine walk? Center of gravity off. Over trimmed. Transom angle wrong in the boat design. Loose steering and other issues.
Do i have the motor trimmed all the way down in to 0% when i do the straight edge measurement for motor height. At the boat yard now doing work and im lost help please.
I learn so much from you. Canadìan mechanics are challenged. Charged me $500 for repair ended up fixing it myself. They handed back to me still missing it was an injector.
Hey I want to thank you for sending me the link to this video it helped me a lot I'm still working on replacing the transom on this project boat but just as soon as that is finished I'll be ready to look for a motor and I'm glad I watched this video because now I know what size in length motor I will need
A very well made video ,hats off to the marine mechanics that did the job ,well done also . You definitely want experience techs on the job like these guys were.
I love the way you teach. Even I am not an expert, I can understand. .Thanks to share your skills and keep doing this great job for the nautical community.
Your guideline for cavitation plate is good since it is based on function. I was not aware that a plate running below water level could cause problems but it makes sense especially in a turn. Most boats I see at boat shows have the engines mounted what appears to be low. I look at the cav plate WRT the trailing edge of the hull. Most are below the running surface of the boat so probably end covered. I put jack plates on my twin engine 26’ center console. It took 1.75” to get the cav plates running on the surface. Everything seemed to run so much more smoothly and the fuel consumption really improved. The Yamahas have fuel rate consumption to 2 decimal points. My background is engineering so I watch the abstract stuff just for fun. I’m gonna end up on somebody’s front lawn soon. Good thing the wife has no interest and has a loud scream. She watches where I think I’m going. Perfect relationship.
Thank you! Yeah, those little things do make a big difference. And jack plates really give you the ability to play around with it. Isn't it amazing how the fuel economy goes up after you get rid of that extra drag?! Hahaha that's funny, the perfect partner lol
Hey Greg, Did elevating the cavitation plate help with top speed? My comment from above Recently bought a boat. I'm having issues with top speed being slower than pretty much everyone on any forum. Its a 1995 Grady White Adventure 208 with Yamaha F200. My anticavitation plate is level with the bottom of the hull. It also rides a little more nose high than other boats I've been on when on plane.
I love your videos like this so much advice I watch over and over to absorb all of it. Canada with the 3-month summer there are nobody this experienced I learn so much from you.
Well if you insist on producing videos like these then I must insist on subscribing! Very well put together and a informative. I am not re-powering, I am fitting a pod to a 1978 Haines Hunter (Copy of an old 17 foot Bertram I believe). Thank you again and see you on the next one.
next time, have a place to hang the motors after removal straight from the boat to the hangers then onto the creates after new motors are installed next time cut the bolts off when there's enough space between the bracket and boat so you dont torque damage the transom next time, install hydrophilic or electric jack plates. ( a must ). You need full up, down, forwards, and back adjustability while under way at high speed to get it dialed in perfectly on the go . Seal them up water tight 1st and let them dry......... THEN mount e motors. next time, install motor leashes ( aka seat belts ) Nice boat . great channel .
Nice, interesting channel and I don't even boat or have ever been on a boat lol. This channel has a quality, quality looking look, very real looking WOW! Looks like I'm right next to you in real life lol. Cameras are getting real looking now.
I knew that my yamaha 90hp, 4 stroke was not at the right height on my boat but didn't know how to set it to the proper height until 3:40 in this video. I need to raise my motor approximately 4.5 inches. Thank you.
Very interesting and very useful soo many people. I need one question can you teach me how measure transom in outboard engine single, double, and triple engine, Can you make one video detaily ? And how should be measure tie bar?
Hi there, long time fan...I have a couple of quick questions and hope you dont mind answering.. I have a 1986 restored 26 foot mako with a used 2012 yamaha 250 outboard. Question 1.- is it normal for that year mako to lean to the right when in grear running at around 4k rpms??? Question 2 whe the low oil presure comes on on the tachometer where do i star? To see if it needs oil? Is there a dip stick like on a car ?? Or do ibhave to take it in to a shop ??
Amazing Channel & QUALITY videos. Would you be willing to make a video on mounting jack plates? I’m looking to raise my engine height 3-4 inches but am in the top hole. Thank you!!!
Love the channel and thanks for all the real world tips and techniques. I have a suggestion video. Can you do one on replacing lower damper mounts. I want to tackle this on my Yamaha F250
Hey Andy! Thank you, I dont have any footage of replacing those mounts. I can see what I can do about helping get you the info to do so though. Youre talking about the motor mounts right? Those arent that bad and you should be able to do it yourself for sure. You'll want new nuts and stuff before you start, and you might even need new bolts depending on how the old ones come out. If I remember correctly they are either an 18 or 19 mm. It's been awhile since I've done one, usually only when changing out the mid sections on the 225s that rot out.
I know this is an older video but I have a project boat I'm working on and I need to know do I need a long Shaft or short shaft motor can you tell me how to determine this
Thanks was just thinking about how to mount a outboard .bought a proline the a Yamaha 200 that when running water roll back up motor in to foot well not sure it mounted right. After this video on how to mount now I can check .thanks.
Very informative! Looked like one of the water pickup holes was above the straight edge, is that acceptable in your view or was this adjusted beyond what was shown in the video?
The water will rise greatly on this particular hull design, and the water pickups are a good distance back. If the back of the boat did not have this much setback from the hull, it wold probably be too high.
Really helpful video as many of yours ! The engine height at water pickup is valid also for a single outboard unit? Mine is placed with anti-ventilation lower face 1in above keel line. I've a stepped hull.
Thank you! Yes, you want that plate above the water but the pickups below the water coming off the back of the boat :) especially on a stepped hull because they aerate the water a lot!
@@BornAgainBoating Many thanks, understood. My feeling is that when the engine is another inch up, the prop will start to ventilate more easily cause also to step water aeration. Am I right ?
In my outboards manual it says to mount the outboards anti ventilation plate slightly LOWER than the boats keel ( 10mm to 30mm ) which is wrong .... glad I didnt follow that advice , good to see the correct advice in this video , ended up mounting my outboards antiventilation plate about 20mm higher than the keel , couldnt go any higher but another 10 or 15mm higher would be ideal .

Have you ever dealt with a first gen cape horn 24? Cape recommends that the engines be mounted on the lowest setting but the boat porpoises bad with no tabs and just sucks fuel. I believe they are too low and others with the same hull and issue do too. Just wondering if youd done it before
Thanks for the informative and interesting rigging video! One question and it has nothing to do with the engine rigging part...@ 2:08 what in the heck is that cobbled-up fiberglass patch job?!!? I thought Yellowfin had better workmanship than what I see in that segment. It was obviously done after the original engines were installed.
You're welcome! Thank you for commenting. Hahaha, it's amazing what you can find deep in the depths of a boat! To be honest, I have no idea what is going on there, some of the boats that we work on get a ton of abuse put on them and you never know what you might find. Yellowfins are a great boat, but they are still made out of wood too. Transoms take such an abuse, especially in heavy heavy seas with all the weight and torque of the engines. I'm not sure who patched that up or if it was just done to give a little more strength to the transom. Thanks for noticing!
Thanks, these instructions can be adapted to help us poor folks too with our little bitty motors. Talk about outa the fryin pan into another? What was wrong with the original “Verados”...not fast enough? Did this guy lose his “truck nuts”?😂
Hull with a straight edge the water pick ups are about 6 or 7 inches lower then the bottom of the straight edge and the out board as high as it can be mounted .Thanks for the info on mounting an outboard .i just bought an older pro line with a 200 Yamaha 2003 check the the bottom of the . Not sure how to fix or I need to add a jack plate to lift motor up higher.
Is propeller ventilation an issue with the engine heights set as described in the video? The trick on powering the engine to adjust trim to match the transom angle is really helpful! Greg
Yup! If you mount it up to high even on a single engine application the anti-ventilation plate will be above the water and you'll suck air around the prop as well as air into the water pick-ups. Causing the engine to overheat and have issues :( Thank you!
Cavitation and ventilation are different. The plate above the propeller is an anti-ventilation plate, prevents air from entering the propeller from above while running. Cavitation is the collapsing of small negative pressure bubbles
I was wondering,..how do you add a power pack to adjust your tilt to the transom on most motors? Or can you just let the pressure off with a screwdriver on the tilt motor and do it manually?
You can do it manually, but you can also just like you said put a power pack on the engine where the power and ground cables go and use the trim. Or like Mercury needs clean power, so you can just pull the wires that go to the trim unit out and disconnect the bullet connectors and then put power to them there to run the trim and get the angle you need.
The best motor/transom match is the one where water flow at speed skims right under the upper small plate, that's under the protruding front lip. Once there prop will work spot on on all water cond ranging from flat calm to choppy, windy water conditions. From there can go straight for a prop maximization to pull wot revs up towards middle to max wot rpm range as usually loaded. Once there and with deck load evenly distributed , combo will achieve a superb fast hole shot plane. To check that spot on height must pull head out transom and visually check what's going on at back of motor, will know if in need to raise or lower a tad the motor as this is not a wild guessing motor installation.
"Water Pressure Gauges"; By now, most outboard manufacturers have adopted the "exhaust out the prop" dump. For all the Merc Lovers, please always "Keep and Eye On" those water pressure gauges. Whether. Nylon or Plastic, the impellers that drive cold water from beneath the Cavitation Plate up and into the engine block, will melt down in seconds, if sufficient water pressure Isn't consistently maintained, especially if you like to Trim the engine out creating less hull contact with lake or ocean water. (don't ask how I discovered this) I ran a 3 blade Cleaver (on an outboard?) a Cleaver tends to "Pick the transom area Up and Out" of the water And so; Trimming raises the front of the hull out of the water and then, the cleaver raises the back! Mucho airborne with a slight "walking to the right from time to time". Got 86mph on a 21 Challenger with One 300 Black Max. (one hand on the wheel) My mistake was (to cheap to) go for the ModVP 270hp EFI! 13 grand for the 300 Black Max/18 grand for the VP! doy. Always had to; "go lay down for an hour", after a great boating day! Sincerely your Retired Salvation Army Major
Hat is the difference in fuel consumption between running one 40 horse as to two 20 horse kickers? And what is the reason that anyone goes for 3 or more? They just dont make engines bigger?
Hi Born Again, If is only two engines on a mono hull they have to tilt sligtly outside as the video shows or turn them sligtly facing the front keel? Thank you for the videos, all the way from Moçambique! The best channel
@@BornAgainBoating On the video at minut 5'.54ss you mention that if is desire the boat to go straingh, the engines must " toe in slightly " but on the diagram you showed, the engines exactly are toe out!???
@@BornAgainBoating I got it now, 🤙🏾🤙🏾🤙🏾keep the engines straight and compensate slightly on the tild bar by extending abit, this of course will reflect in the propeller, and keeping the bow stright and balanced, top top. Best channel for sure. Hugs from Mozambique
Ive got a question about cav plate height. So for every foot back from the transom it should be one inch above the hull? If to low would it cause the boat to porpoise?
Generally between 1/2-1" for every foot yes. If it is to low, then the anti-ventilation plate will get pulled under the water and yes it can cause porpoising. You can have someone with you and run the boat and just go back to the transom and look down, you'll be able to see if it is sunk under the water or riding just on top of the water! :)
@@BornAgainBoating I have a friend that just hung a set of new Yamaha 200s on his 25.5 Stamas and I keep telling him the motors are mounting way to low, I'll show him this video to support my case. 👍
Yup, Yamaha & Mercury have that same issue. You can buy a Suzuki all day though! Both the Merc & Yami's some aren't available until the second quarter of next year!
Question. New to me boat that had motor mounted to deep and I installed trim tabs. The through hull drains and live well fitting caused me to mount tabs closer to motor and now wake from tabs are hitting motor and giving better hole shot. Should this be corrected? If so then what.
Hi, I have a Yamaha 9.9 kicker that I want to install on my 23 Grady closed transom. What would be the proper height for the motor once it is in the down position? Once again your videos are awesome. Keep up the great work!!
honestly - it doesn't matter. the motor is never going to plane the boat. planing , top speed and fuel efficiency is out the window. you have more directional control and more bite on the prop when the motor is deep.
Great video. Thanks for sharing, Just curious is there a big improvement with the 350s also what would that cost, I am guessing somewhere in the 100k range?
To a point, the 350's are pretty well dialed in with minimal issues! For trips, yeah its about in the 100K range, depends on what all you are changing. If just the engines, I want to say it's a bit under 100
As per 3 engine outboards; I'm pretty sue that With Two Outboards, the Propellers swing in forward gear (and reverse) in Opposite directions. In essence, each individual gear case to the propeller would be configured Specifically to do this. How do you manage 3 propellers? In my mind, two of them would be swinging in the same direction. thanks a great video.
@@davidjessee7701 nope, you're right, there's only two control handles. They do what mercury calls "shadow mode". Which just means that when both handles are in the same position whether forward or reverse. The center engine will mimick the two outside engines and go into that gear. Now if you put port in forward and starboard in reverse. The center engine will stay in neutral!
Hey buddy what's that bolt called that's torch down into the top of the flywheel use for removing or installing an outboard on the back of a boat. What is the correct way a motor onto a boat or off of a boat transom
I just installed twin outboard and my boat seems to veer left and right.. the toein is a 1/4” and pulling tape measure on the transom my port engine is 3/16” different center of the motor bolts.. not sure if that’s too much?? Please help!!😢
No, that's not a silly question at all. It depends on the owners and the engines. Some engines arent worth any money, so they get sold to a wholesale that parts then out and scraps the engine. Other engines are sold to a different wholesaler that then repowers boats and sells them. Sometimes the owners have someone that they want to give the engines too or sell them too and then sometimes the owners want any too much money for them and so no one buys them and they sit until they are worth even less that they would have if they would have been sold. I guess it really depends on the owner! Great question, thank you for asking :)
Thank you! I think you are talking about the leak down tester. That's used to put compressed air into the engine cylinder and see how much of it leaks out. Leaking past the rings and the valves.
Nice video I have a question I check my 30 Donzi with twins 250s yamaha trim all the way in and the line goes like 1/2 inch over the top of the water pick up the are 2 feet back from the bottom of the hull they are set now on the second from the top hole so I guess I need to go up at least one more hole what you guy’s think thanks and i will appreciate you’re help
where should the anti-ventilation plate sit in a single motor application? I have a single 130 E-TEC on my 17'7'' Pionner Sportfish and have always thought it sat too low.
Hello, sorry for the confusion. No I can't because every boat is different. That is why you have to measure between the steering arm and the propshaft. Compare the two distances and turn the propshafts in about a 1/4 more than the steering arms.
Measuring mounting height- question. Does it matter if it’s Suzuki vs mercury using the straight edge water pickup method? I’m considering one hole up bc the motor looks buried. But will try and see where I land with the straight edge. Thank you
Certainly! You'll probably notice that on all boats that have triples or quads that the two outside engines are either mounted higher or they are a shorter driveshaft length than the center engine or engines. That is just simply to form to the hull of the boat. As the water comes off of the bottom of the hull, the only thing you want in the water is the lower unit. So that the water doesn't go over the anti-cavitation plate and suck the back of the boat down and make it perform poorly in the water. Most of the time the center engine is a 30 inch driveshaft and the outsides are 25 inch. On quads the center engines are still 30's but depending on the hull, the outsides will be 20 inch driveshaft's! Hopefully this helps out, let me know if you want to know something else! Thank you for commenting!
Nice vid, when i was working in a marine shop 13yrs ago in fit-outs we were told never lay a change over engine (re-power) flat on its side always use an engine stand so as not to get water run back in the bores i couldnt work out that theory cause all engines arrive from the manufacturer run and tested in a water tank on a cradle layed face down although not on its side nearly all were 2 strokes re-powered to 4 strokes would that have been why i never bothered to query it just obeyed their directions
Lol yeah probably. To be honest we prefer to put them on stands too. Just right now there are literally no stands left! Tons of people transport them on their side on pallets all the time though, so, sounds like it was probably a personal preference of the business.
Thanks for the great video, I check my Suzuki’s 300 on the HydraSport 28 and found out that the water pick up is 2” below the bottom hull at 33” out ,I always thought they were low when they repower my boat .please let me know if this is done with the engine in all way or level with the bottom hull, thanks again
Thank you! That does sound to be a little low. The main thing is that you don't want that cavitation plate to be under the water coming off of the bottom of the hull when you are running. Generally you check this with the engine tilted all the way down or all of the way in! What are you planning on repowering with?
Thanks again Sorry for the delay a wanted to check it out before it turns out that I get the same results 2” from the bottom of the hull to the top of the water pick up engine level to the hull and 2” from the bottom of the hull to the top of anti cavitation plate with the engine down all the way . So because of your great video I learned that I have to lift the engine 2 holes I’m in the middle now so I have to go to the bottom holes I’ll be 1”1/2 up . I was doing 55mph at 6250 Rpm with 2 economy, I got the 300 last year but I would’ve gone to you guys you show that you know you’re work well thanks
my 1997 xr6 EFI 2stroke 150hp tops at 60mph at that speed I have to struggle keeping the steering straight. After watching this video, you mentioned toeing in the engine to keep it straight. Is this still a possibility for me. If so, how??
Well, the toeing in only works for twins and above, but for singles, it might just be because so much of the boat is out of the water, you do lose some steering there because of the speed. Otherwise you might have a little bit of slop in the helm or the steering cylinder :)
My transom is 20in. So do I need a 20in shaft motor? Right now on the boat it’s a 25in shaft. Seems run fine. But I’m going to repower and want to go with the right size.
Every transom is different, if its running fine, you probably don't need to change it. Depends on how the engine sits when its mounted. Make sure the plate isn't buried in the water
my Yamaha F150XB single motor rubs on the mount when I trim it down, can I adjust that? It's the little wings that stick off the motor that fit between the wings on the transom motor mount, slows my trim down when it comes in contact. Maybe a topic on how to adjust that? Looks like one big bolt.
Sounds like the engine has twisted a little bit, youll have to look around it and figure out how to adjust it by experimenting lol thats not an everyday problem or adjustment
Why 4200 and not 5200 i have to do my power trim pump replacement on 150 verado on boston Whaler outrage and it is turning into a nightmare! can you cut 4200 off easier?
So i have a center console with a single verado 300 on a 28" bracket. I noticed cruising at 3800 rpm... Trimmed up... My cav plate is fully submerged... Cant see it at all. So i pulled the boat and measured as shown in the video here and it is set up almost exact as show. The top of the straight edge to the bottom of cav plate is 2.5"... Should i raise it a couple more inches?
Raise it up one hole on the bracket and see what that does, but take into consideration at wide open throttle the set up might be perfect :/ sounds like a heavier boat, so at cruising speed like 3800 the boat is sitting deeper in the water and so the water is able to flow over the top of the plate
Sounds good! Thanks for the reply! The motor right now is as high as it can go. The boat is a 25 Proline center console. I ordered a static jackplate to lift it up another couple inchs. I will run it WOT and check again before installing the jack plate. Thanks again for the reply!
Hey i got a question. Im building a rc boat with outboard electric motor. I have a single and have my prop jus a little below the bottom of my boat. It seems to drag and not get on plane and sucks air and makes prop spin free till it grabs more water. Can you help with advise?

My anticavitation plate is level with the bottom of the hull. It also rides a little more nose high than other boats I've been on when on plane.
Are you propped out correctly and what kind of prop are you using?
Also is the bottom of boat clean? Also check for trapped water in hull.
Also are you sure your motor is running properly?
What is your rpm at full throttle with about half trim?
I always use dielectric at all electrical connections
Man this was a great video🤘🤘🤘👍👍👍
Thank you so much! I hope they are becoming more informational:)
Have you ever dealt with a first gen cape horn 24? Cape recommends that the engines be mounted on the lowest setting but the boat porpoises bad with no tabs and just sucks fuel. I believe they are too low and others with the same hull and issue do too. Just wondering if youd done it before
Thanks for the informative and interesting rigging video! One question and it has nothing to do with the engine rigging part...@ 2:08 what in the heck is that cobbled-up fiberglass patch job?!!? I thought Yellowfin had better workmanship than what I see in that segment. It was obviously done after the original engines were installed.
You're welcome! Thank you for commenting. Hahaha, it's amazing what you can find deep in the depths of a boat! To be honest, I have no idea what is going on there, some of the boats that we work on get a ton of abuse put on them and you never know what you might find. Yellowfins are a great boat, but they are still made out of wood too.
Transoms take such an abuse, especially in heavy heavy seas with all the weight and torque of the engines. I'm not sure who patched that up or if it was just done to give a little more strength to the transom. Thanks for noticing!
Yes And i have think abaut bay o boat from USA. Now ?????
What should be the minimum gap between 2 OBMs or while installing multiple OBMs
Thanks, these instructions can be adapted to help us poor folks too with our little bitty motors.
Talk about outa the fryin pan into another? What was wrong with the original “Verados”...not fast enough?
Did this guy lose his “truck nuts”?😂
You said you drill the holes to remove the 5200. Then you said you use 4200 to install the motor bolts. Confused on this question. 3M 4200 or 5200?
Hull with a straight edge the water pick ups are about 6 or 7 inches lower then the bottom of the straight edge and the out board as high as it can be mounted .Thanks for the info on mounting an outboard .i just bought an older pro line with a 200 Yamaha 2003 check the the bottom of the . Not sure how to fix or I need to add a jack plate to lift motor up higher.
Is propeller ventilation an issue with the engine heights set as described in the video? The trick on powering the engine to adjust trim to match the transom angle is really helpful! Greg
Yup! If you mount it up to high even on a single engine application the anti-ventilation plate will be above the water and you'll suck air around the prop as well as air into the water pick-ups. Causing the engine to overheat and have issues :( Thank you!
Cavitation and ventilation are different. The plate above the propeller is an anti-ventilation plate, prevents air from entering the propeller from above while running. Cavitation is the collapsing of small negative pressure bubbles
Thank you! ruclips.net/video/KbFa1fmlAXg/видео.html
I was wondering,..how do you add a power pack to adjust your tilt to the transom on most motors? Or can you just let the pressure off with a screwdriver on the tilt motor and do it manually?
You can do it manually, but you can also just like you said put a power pack on the engine where the power and ground cables go and use the trim. Or like Mercury needs clean power, so you can just pull the wires that go to the trim unit out and disconnect the bullet connectors and then put power to them there to run the trim and get the angle you need.
@BornAgainBoating that's awesome because I have recently started rigging boats...thanks a bunch man!
Nice job guys!
Fish On Forte! Thank you!
The best motor/transom match is the one where water flow at speed skims right under the upper small plate, that's under the protruding front lip. Once there prop will work spot on on all water cond ranging from flat calm to choppy, windy water conditions. From there can go straight for a prop maximization to pull wot revs up towards middle to max wot rpm range as usually loaded. Once there and with deck load evenly distributed , combo will achieve a superb fast hole shot plane.
To check that spot on height must pull head out transom and visually check what's going on at back of motor, will know if in need to raise or lower a tad the motor as this is not a wild guessing motor installation.
"Water Pressure Gauges"; By now, most outboard manufacturers have adopted the "exhaust out the prop" dump.
For all the Merc Lovers, please always "Keep and Eye On" those water pressure gauges.
Whether. Nylon or Plastic, the impellers that drive cold water from beneath the Cavitation Plate up and into the engine block, will melt down in seconds, if sufficient water pressure Isn't consistently maintained, especially if you like to Trim the engine out creating less hull contact with lake or ocean water.
(don't ask how I discovered this)
I ran a 3 blade Cleaver (on an outboard?) a Cleaver tends to "Pick the transom area Up and Out" of the water
And so; Trimming raises the front of the hull out of the water and then, the cleaver raises the back!
Mucho airborne with a slight "walking to the right from time to time".
Got 86mph on a 21 Challenger with One 300 Black Max. (one hand on the wheel)
My mistake was (to cheap to) go for the ModVP 270hp EFI!
13 grand for the 300 Black Max/18 grand for the VP! doy.
Always had to; "go lay down for an hour", after a great boating day!
Sincerely your Retired Salvation Army Major
This is great.. do u use the straightedge with the outboard fully trimmed down?
Any videos on how to clean up an old console and make it look good?
Detailing isn't my best talent lol we might show something like that on the Ocean Master Project before the end of it!
Born Again Boating ok cool, I’ll keep an eye out for it
Where can I get this done in Texas
good stuff. suggest topic " " intermitent overheating engine in fresh water"

Hat is the difference in fuel consumption between running one 40 horse as to two 20 horse kickers? And what is the reason that anyone goes for 3 or more? They just dont make engines bigger?
Hi Born Again,
If is only two engines on a mono hull they have to tilt sligtly outside as the video shows or turn them sligtly facing the front keel?
Thank you for the videos, all the way from Moçambique!
The best channel
Thank you! You shouldn't have to "tilt" either of the engines, they should be straight up and down on the transom :/
@@BornAgainBoating
On the video at minut 5'.54ss you mention that if is desire the boat to go straingh, the engines must " toe in slightly " but on the diagram you showed, the engines exactly are toe out!???
@@BornAgainBoating I got it now, 🤙🏾🤙🏾🤙🏾keep the engines straight and compensate slightly on the tild bar by extending abit, this of course will reflect in the propeller, and keeping the bow stright and balanced, top top.
Best channel for sure.
Hugs from Mozambique
Ive got a question about cav plate height. So for every foot back from the transom it should be one inch above the hull? If to low would it cause the boat to porpoise?
Generally between 1/2-1" for every foot yes. If it is to low, then the anti-ventilation plate will get pulled under the water and yes it can cause porpoising. You can have someone with you and run the boat and just go back to the transom and look down, you'll be able to see if it is sunk under the water or riding just on top of the water! :)
How do you setup the toe-out for triples motors?
Damn nice video. Thanks again
Thank you!
Where does one buy those used engines?
Thank you for this video!! My questions have been answered.
That's great! Thank you for commenting :)
@@BornAgainBoating I have a friend that just hung a set of new Yamaha 200s on his 25.5 Stamas and I keep telling him the motors are mounting way to low, I'll show him this video to support my case. 👍
Hahahha awesome! Stamas is a good boat and those 200's are great too. Was he able to get the DEC's or the regular's?
Regulars, I guess people are having trouble getting the DECs too much demand and not enough Supply...
Yup, Yamaha & Mercury have that same issue. You can buy a Suzuki all day though! Both the Merc & Yami's some aren't available until the second quarter of next year!
Question. New to me boat that had motor mounted to deep and I installed trim tabs. The through hull drains and live well fitting caused me to mount tabs closer to motor and now wake from tabs are hitting motor and giving better hole shot. Should this be corrected? If so then what.
Hi, I have a Yamaha 9.9 kicker that I want to install on my 23 Grady closed transom. What would be the proper height for the motor once it is in the down position? Once again your videos are awesome. Keep up the great work!!
honestly - it doesn't matter. the motor is never going to plane the boat. planing , top speed and fuel efficiency is out the window.
you have more directional control and more bite on the prop when the motor is deep.
Great video. Thanks for sharing, Just curious is there a big improvement with the 350s also what would that cost, I am guessing somewhere in the 100k range?
To a point, the 350's are pretty well dialed in with minimal issues! For trips, yeah its about in the 100K range, depends on what all you are changing. If just the engines, I want to say it's a bit under 100
As per 3 engine outboards; I'm pretty sue that With Two Outboards, the Propellers swing in forward gear (and reverse) in Opposite directions.
In essence, each individual gear case to the propeller would be configured Specifically to do this.
How do you manage 3 propellers?
In my mind, two of them would be swinging in the same direction.
thanks a great video.
You are exactly right! The middle engine is another right-hand gear case. Then the port is still a left-handed case.
Thank you!
@@BornAgainBoating sub'd
Thank you!
Kinda on the same subject.. How is the 3 motors controlled with two controls? Or did I miss something?
@@davidjessee7701 nope, you're right, there's only two control handles.
They do what mercury calls "shadow mode". Which just means that when both handles are in the same position whether forward or reverse.
The center engine will mimick the two outside engines and go into that gear. Now if you put port in forward and starboard in reverse. The center engine will stay in neutral!
I don't want no Mercury. What is the top speed difference
Hey buddy what's that bolt called that's torch down into the top of the flywheel use for removing or installing an outboard on the back of a boat. What is the correct way a motor onto a boat or off of a boat transom
Uriu.....think I was half asleep when I typed this.
I just installed twin outboard and my boat seems to veer left and right.. the toein is a 1/4” and pulling tape measure on the transom my port engine is 3/16” different center of the motor bolts.. not sure if that’s too much?? Please help!!😢
Best left to the pros but good video
You use 304 or 316 SS bolts on transom?
what is that glass and putty mess at the 2:09 mark?
Thanks for the great video, and what offset measurements would be good for twin 200 on a 25’?
Might seem like a silly question but when someone repowers a boat, what do they usually do with the old engines? Are they traded in on the spot?
No, that's not a silly question at all.
It depends on the owners and the engines. Some engines arent worth any money, so they get sold to a wholesale that parts then out and scraps the engine.
Other engines are sold to a different wholesaler that then repowers boats and sells them.
Sometimes the owners have someone that they want to give the engines too or sell them too and then sometimes the owners want any too much money for them and so no one buys them and they sit until they are worth even less that they would have if they would have been sold.
I guess it really depends on the owner! Great question, thank you for asking :)
Thanks!! I always imagined the owner hauled the boat plus the old engines home after the install - which would be a major pain I'm sure
You're welcome! Thank you for commenting! Yeah, most people don't want to have an outboard laying on a pallet in their front yard :) lol
Thanks sir, finally what are using snap on equipment , this one compression equipment ? Can you explain
Thank you! I think you are talking about the leak down tester.
That's used to put compressed air into the engine cylinder and see how much of it leaks out.
Leaking past the rings and the valves.
Nice video I have a question I check my 30 Donzi with twins 250s yamaha trim all the way in and the line goes like 1/2 inch over the top of the water pick up the are 2 feet back from the bottom of the hull they are set now on the second from the top hole so I guess I need to go up at least one more hole what you guy’s think thanks and i will appreciate you’re help
where should the anti-ventilation plate sit in a single motor application? I have a single 130 E-TEC on my 17'7'' Pionner Sportfish and have always thought it sat too low.
You'll want to take a yard stick and check to make sure it's sitting like the video shows :)
Can I get used engines
How much does that process cost?
I don't understand tie bar
Can you please tell me exactly how much distance should be
Hello, sorry for the confusion. No I can't because every boat is different. That is why you have to measure between the steering arm and the propshaft. Compare the two distances and turn the propshafts in about a 1/4 more than the steering arms.
good day . I am interested in a bolk of cylinders with spores and a crankshaft of mercury 150 fore stock. if so how much can he
Does the height adjustment work for aluminum boats also?
Yes!
Measuring mounting height- question. Does it matter if it’s Suzuki vs mercury using the straight edge water pickup method? I’m considering one hole up bc the motor looks buried. But will try and see where I land with the straight edge. Thank you
Nope, brand manufacturer doesn't matter, height is gauged on the plate and water pick is
Transom bracket on a small boat
I used to build the in board mercury engine's in Stillwater Oklahoma
That's awesome, we don't see a lot of those down here
Why the outboards at the extremity are always mounted higher than the one at the center ? Can you explain that ?
Certainly! You'll probably notice that on all boats that have triples or quads that the two outside engines are either mounted higher or they are a shorter driveshaft length than the center engine or engines.
That is just simply to form to the hull of the boat. As the water comes off of the bottom of the hull, the only thing you want in the water is the lower unit. So that the water doesn't go over the anti-cavitation plate and suck the back of the boat down and make it perform poorly in the water.
Most of the time the center engine is a 30 inch driveshaft and the outsides are 25 inch. On quads the center engines are still 30's but depending on the hull, the outsides will be 20 inch driveshaft's!
Hopefully this helps out, let me know if you want to know something else! Thank you for commenting!
Born Again Boating Thank’s a lot for this rewarding answer 😊

Nice vid, when i was working in a marine shop 13yrs ago in fit-outs we were told never lay a change over engine (re-power) flat on its side always use an engine stand so as not to get water run back in the bores i couldnt work out that theory cause all engines arrive from the manufacturer run and tested in a water tank on a cradle layed face down although not on its side nearly all were 2 strokes re-powered to 4 strokes would that have been why i never bothered to query it just obeyed their directions
Lol yeah probably. To be honest we prefer to put them on stands too. Just right now there are literally no stands left!
Tons of people transport them on their side on pallets all the time though, so, sounds like it was probably a personal preference of the business.
@@BornAgainBoating Cheers.
@@Ken-fisho cheers!
Thanks for the great video, I check my Suzuki’s 300 on the HydraSport 28 and found out that the water pick up is 2” below the bottom hull at 33” out ,I always thought they were low when they repower my boat .please let me know if this is done with the engine in all way or level with the bottom hull, thanks again
Thank you! That does sound to be a little low. The main thing is that you don't want that cavitation plate to be under the water coming off of the bottom of the hull when you are running.
Generally you check this with the engine tilted all the way down or all of the way in! What are you planning on repowering with?
Thanks again Sorry for the delay a wanted to check it out before it turns out that I get the same results 2” from the bottom of the hull to the top of the water pick up engine level to the hull and 2” from the bottom of the hull to the top of anti cavitation plate with the engine down all the way . So because of your great video I learned that I have to lift the engine 2 holes I’m in the middle now so I have to go to the bottom holes I’ll be 1”1/2 up . I was doing 55mph at 6250 Rpm with 2 economy, I got the 300 last year but I would’ve gone to you guys you show that you know you’re work well thanks
That's awesome! Congrats on the repower! Thank you so much for your comment :)
my 1997 xr6 EFI 2stroke 150hp tops at 60mph at that speed I have to struggle keeping the steering straight. After watching this video, you mentioned toeing in the engine to keep it straight. Is this still a possibility for me. If so, how??
and, I do have power steering. Several of my fishing buddies have the same problem. Is this an older people problem, or older boat problem?
Well, the toeing in only works for twins and above, but for singles, it might just be because so much of the boat is out of the water, you do lose some steering there because of the speed. Otherwise you might have a little bit of slop in the helm or the steering cylinder :)
That works. I have twins and was getting a steering "kick" feel in the wheel. I towed the props in 3 turns on the tie bar threads and problem solved.
hi can anyone please help me on the right outboard height on my step up hull please i believe its to low but need professional advice tia
My transom is 20in. So do I need a 20in shaft motor? Right now on the boat it’s a 25in shaft. Seems run fine. But I’m going to repower and want to go with the right size.
Every transom is different, if its running fine, you probably don't need to change it. Depends on how the engine sits when its mounted. Make sure the plate isn't buried in the water
my Yamaha F150XB single motor rubs on the mount when I trim it down, can I adjust that? It's the little wings that stick off the motor that fit between the wings on the transom motor mount, slows my trim down when it comes in contact.
Maybe a topic on how to adjust that? Looks like one big bolt.
Sounds like the engine has twisted a little bit, youll have to look around it and figure out how to adjust it by experimenting lol thats not an everyday problem or adjustment
@@BornAgainBoating Well the whole boat burned the other day so now I'll just buy a new one with the insurance.
Why 4200 and not 5200 i have to do my power trim pump replacement on 150 verado on boston Whaler outrage and it is turning into a nightmare! can you cut 4200 off easier?
Mainly because 4200 doesnt run like 5200 does, so it's easier to work with :)
So i have a center console with a single verado 300 on a 28" bracket. I noticed cruising at 3800 rpm... Trimmed up... My cav plate is fully submerged... Cant see it at all. So i pulled the boat and measured as shown in the video here and it is set up almost exact as show. The top of the straight edge to the bottom of cav plate is 2.5"... Should i raise it a couple more inches?
Raise it up one hole on the bracket and see what that does, but take into consideration at wide open throttle the set up might be perfect :/ sounds like a heavier boat, so at cruising speed like 3800 the boat is sitting deeper in the water and so the water is able to flow over the top of the plate
Sounds good! Thanks for the reply! The motor right now is as high as it can go. The boat is a 25 Proline center console. I ordered a static jackplate to lift it up another couple inchs. I will run it WOT and check again before installing the jack plate. Thanks again for the reply!

Hey i got a question. Im building a rc boat with outboard electric motor. I have a single and have my prop jus a little below the bottom of my boat. It seems to drag and not get on plane and sucks air and makes prop spin free till it grabs more water. Can you help with advise?
Try and lower the engine a little bit :) or weight down the boat a little bit
Ventilation plate. Cavitation is at the prop blades.
Anti ventilation plate
what distance apart do the motors have to be ? for optimum performance? cheers ben]
That can vary, most of them start at around 26 inches center to center. Mostly depends on the transom of the boat.
