Thank you. In this video I was running the stock Quicsilver 13P prop. I damaged that one and now have a Solas 13P on it which performs almost identically. I would like to try a 15P on this motor with my light 14 foot boat. I think this motor has more to give than I'm getting woth the 13P on this boat. Thanks for watching!
The "auto" in this case only means that the forward-neutral-reverse and the throttle is all controlled by twisting the tiller grip. It can be converted to remote controls and a wheel with a batch of parts. Thanks for watching!
I guess I’ve had a different experience with the automatic than you have. I believe mine throttles later in the twist than yours, in either direction. You twist mine to shift, and then give it a bit more to get it above idle. On mine it seems very slick, intuitive and modern, yet the old girl is old.
This one isn't bad. It's just a lot more complicated under the cover than a motor with a separate shifter. Mine will shift into gear at idle and then throttle up also. I think my carburetor may be die for a cleaning too. I have never done anything to this motor but change the impeller and gear oil. This one doesn't like to idle real well in gear. Part of the issue also seems to be that it sits a little too low in the water with only myself in the boat. Maybe the added backpressure is what is making it not idle the best and a little harder to start than it should be. One thing that is really nice about it is that you can put a tiller extension on it and still shift without a separate control. Thanks for watching!
Love the Yikes! That crunche gets me too on mine. Sounds like marbles in a blender but goes like stink. Mine is an 1985 25XD hit 40kmh with 500lbs in a 14' spectrum hd so your bang on with 25mph.
Yeah, that clutch dog grinding is a pet peeve of mine. With the auto shift transmission on these, it is difficult at times to get the motor to shift and not either grind or accelerate too rapidly. Rapid acceleration in reverse can equal bad news on a short transom without a splashwell. I think thus motor gas a little more to give on this boat woth a bit more prop pitch. It just screams with the 13P on this motor. I do believe I can still get about 25mph with a passenger and gear with this setup. Thanks for watching!
Mike Stefano Yes, this thing is a screamer. It needs a steeper prop for this light of a boat. 15P should make it borderline scary. Stock prop is 13P. I need to try running this motor on my Alumacraft FD. It makes the Sea Nymph 14R kinda squirrelly. Thanks for watching!
Old JohnnyRude I don’t know much about props but I have a 25xd on my pontoon. It doesn’t seem to wind out as high as this one does. Do you have a prop recommendation?
@@Natter20002 If it’s not revving as high as it should that means it needs a lower pitch prop. Depending on the size of the pontoon boat it may not have enough power to get it moving
It's a screaming powerhouse. That's for sure. It's been a good motor and it's one I won't get rid of. This is one of my newest motors. Most of mine are around 60 years old give or take a few years. Thanks for watching!
Yessir! That is is Ron. I have to keep messing with the trim settings to try to get it right. I think it has a little more speed in it, but that might be prop too. I know just when you think it is tapped out, there's still more twist in the grip.
Dude let it run for at least 40 seconds before you jam it in gear and turn down the idle a bit and you will learn your lesson reversing like that do you live up north?
Frank Bradley This was not a cold start. It had been running for 20-30 minutes before I shut it down to take this video. It was only stopped for a couple minutes before I restarted it. It warmed up for a couple minutes before I took off from the cold start and I didn't take off WOT from a stop. If I were to turn the idle down, it would not start or stay running. The neutral position on the tiller grip is start position of the throttle and it does not idle down as low as a motor with separate throttle and shift controls. When I shifted to reverse, I was trying not to take off too quickly in reverse and take water over the transom in the chop that day. I ended up taking some water anyway once I was moving in reverse. My slow shift resulted in the shift dog banging the reverse gear (that sound you never want to hear). There was no lesson to be learned here that I didn't already know. No I don't live up north. We have a cabin up there. Thanks for watching.
Dude you are trying to school the teacher JohnnyRude forgot more about Outboards,than you would ever know , guy could rebuilt a motor blind folded. Think b4 you add your 2 sense (cents) Lol
I have learned a lot about this one and a few others since this video. They are still not my favorite motors, but they had some very good products. I like this motor a lot, but still don't care for working on it. Thanks for watching!
these was really good outboards these was the best of the Mercury outboards these was really good motors they are really to goo be a really good motor to own they are really a good outboard for the day these was really nice motors as i liked these outboards as i knew these was really good motors now
I have this motor a 1986 25hp mercury but it doesn't say xd on it anywhere. Is mine still an xd model. Trying to find some seals for it. Prop seal went bad.
There should be no difference in any of the seals. My understanding is that the XD stands for eXtra Duty. This 25hp is based on the same powerhead, midsection, and gearcase as the 35hp. The XS motor is a direct drive, short shaft racing motor. The XD is a full gearshift fishing motor which is what this one is. Thanks for watching!
Just put new reeds and tuned the carb on my 1980 25, it starts first pull and idles nicely in the tub, can't wait to get it out this coming weekend. I have a great running 1990 15 hp I've been using but it won't get my heavy jon boat up on plane.
Nice! They're nice strong motors. If the '90 15 won't plane your jon boat, it must be a heavy beast. I just ran a '90 Merc 9.9 on my Alumacraft K this past weekend and it was very strong. The K is about 205lbs or so empty and 15'10" long. A fairly fast hull for its size, but I was impressed with the 9.9. I just got a 13P stainless prop for this motor. It is lightly cupped so it should be a good match to the motor. Thanks for watching!
Yes, these are very well built and reliable outboards from my experience and others' accounts that I have read. Good strong runners and mine has been very trouble-free. Thanks for watching!
Those 5.5 OMCs are great little fishing motors. I have a 64 Fisherman also. It is the fastest 5.5 I own.i got 11mph out of this same boat with that motor. Quite impressive for a 5.5hp on a 14ft mod V. Thanks for watching!
Mine is a Solas aftermarket prop, but same dimensions as the stocker at 10 3/8 x 13P. On my might boat running solo, I'm quite sure this motor will swing a 15P prop. Marineengine.com has them for sale. Thanks for watching!
I just spent some time tuning one up, carb was gummed up pretty bad, biggest downfall to that "automatic" is there is no way to rev the engine in neutral, if the motor floods its almost impossible to start without opening the throttle. I ended up removing the interlock that prevents the motor from being pull started while in gear, that helped tremendously. FYI
Yes, you are 100% correct about the inability to advance the throttle beyond the start / idle position while in neutral being the biggest downside to this "automatic" arrangement. The upside is you have full directional control of the motor from a tiller extension. It's a screamer when it's in good tune. I still enjoy running my old 1950s Johnson RDs and Evinrude Big Twins more because I find the ergonomics to be more comfortable. This is a nice motor, though, and I do enjoy running it sometimes. Thanks for watching!
Are you near Manistee Lake or are you in SE Michigan? I do have a couple of motors for sale. Right now a '55 Johnson 10hp, and a '58 Johnson 5.5hp. There will be a few more this year as well.
Awesome. Congratulations on your new motor. This thing is a powerhouse. It is a blast to run. I don't care for the straightness of the tiller, but it has loads of power. Have fun and be safe. Thanks for watching!
I have this same moter. I need to replace the kill switch that is located in the tiller handle. I need to know how to remove the old one before I replace it. How do I do this? Does the rubber grip come off or do I need to remove the tiller handle?
Steven Shimek I have never replaced one of these switches and do not have a manual for this motor. By looking at the replacement switch assembly it appears that it would be unplugged from the harness under the cowl, the tiller grip would have to be removed (the rubber part), and it would be unscrewed from the end of the tiller handle. The wires of the new one would need to be fished thru the tiller and plugged in where the old ones came out, the new switch threaded in and tightened, and the rubber grip replaced. I'd suggest consulting a manual before attempting this, however. Thus is merely speculation on my part.
Either of these for sale? I just refurbished a 1990 amateur race boat/ski/hydroplane thing haha. It's dying to have a fast 25hp merc hanging off the back!
I'm doing well, Bill. I hope you are doing well also. This motor weighs 118 lbs. Its a heavy beast to swap on and off the boat, but it is a screamer! Thanks for watching!
I have the exact same motor 1986 25hp xd. I lost power at w.o.t. yesterday. Was ripping around the river sat just fine, now no power at w.o.t. 5mph tops. Limped it back to the ramp. Still passing water fine, brand new scepter tank, brand new fuel line(black line not gray), and clean fuel filters. Not sure if it's a hi speed jet that plugged or if something else is going on. Any hints?
The first thing I would check is the linkages under the cowl. Make sure the stator plate is moving and the throttle is being opened as the timing is advanced. If all that works, do you know it is still running on both cylinders? If one cylinder dropped, it would drastically reduce the power output. If it is still running on both cylinders, it seems like it may be a fuel delivery problem like a blocked main jet, carburetor flooding, etc. If the engine rpms are coming up, but you cannot get much forward speed, it could be a spun prop hub. I hope this helps, thanks for watching!
@@oldjohnnyrude8404 def not a spun prop as I can't get high rpm out of the motor. Inkages look and function as i believe they should. Can twist to w.o.t. and watch the stator plate move. It's like a fast troll and that's all I get. I did lengthen the fuel line to 14ft in an attempt to put weight forward and added an inline fuel filter when I rebuilt the line. I will try to run it tonight with a short line and no inline filter to try to remove a couple variables. Ill check soark plugs&wiresn check for spark, and after I do that I am thinking if the problem persists I'll tear into the carb to rebuild/clean it out. After I built the new fuel line everything worked just fine one day, then upon start up the next day just a boggy sluggish motor. Definitely seems like a fuel issue as 90% of outboards suffer from them and I can't stand to pay a marine mechanic to do something I can fumble my way through with a little time and education.
@@oldjohnnyrude8404 pretty much start with fuel issues. I haven't worked on an outboard before but I've tinkered with kids mini bikes, go karts etc so it's pretty similar I hope.
fredtflail They're good strong runners. This one has given me no trouble since I have owned it. It's just a pain to drop the LU because the shift rod connection is very difficult to get at.
Johnny Path Does it shift into gear and turn the prop at all? If it is shifting into gear, but it won't get much past trolling speed and then the engine over revs the prop hub is probably spun. The other thing that I can think of is if you have a 20" transom and a short shaft motor, the prop may be ventilating and losing thrust as the boat starts to plane off. I may be able to help, but I may need some more detail or a video.
Your throttle gears inside the motor. Take the hood off n move the throttle n on the left side of the motor you’ll see your connections aren’t together
theeasybeats This one is something different than the automatic transmission that was used in the Mark series auto trans motors. This one has a conventional shifting drive dog in the gearcase. It has a series of cam driven linkages that control the shifting at the same time as the throttle. It is more like the mechanism in a single lever remote shift box under the cover. It is indeed a completely different system than the original Merc auto trans.
OK, I loved the 60's mercs best looking motors of the time but always found OMC motors to be a lot less trouble and easier to work on, love the 2 cycle torque can't beat it thanks
theeasybeats Agree that the 60s Mercs had the looks. They are much more tedious to work on than OMC motor. I have a definite preference for OMC, but I like a little challenge too sometimes. This motor is not a lot of fun to.work.on, but it's a screamer on the boat.
joe cote hey joe. I have the same problem. Idk if the choke works at all. It has a really hard time firing up. Takes lots of pulls n hard to keep running. So a rag helps?
The choke doesnt actually "choke" it like a typical engine, when you pull the lever to full choke it actually depresses a plunger which injects a shot of fuel into the carb, at the same time it pulls a lever which advances the timing to increase the idle rpms. The timing advance is also held in the half choke position...kinda a mess
Hashirama Senju with the stock prop which I'm running in this video, I'm going just over 25mph on GPS. I'm sure it can take more pitch and go faster. It has no problem reaching full rpm.
@@cmj2956 I have Champion surface gap plugs in it now, but I may be changing them to conventional plugs. I'm not really happy with the surface gap plugs. Thanks for watching!
Which tick? The clattering rattle while its running? That is strange. I really cant find anything loose but it still rattles like that. It runs great and has lots of power but it is rattly. The clicking when I went onto reverse was because I changed gears too slowly. I really prefer a separate shift lever to having the gearshift built into the turning of the tiller grip. I still like this motor though. It is a screamer. Thanks for watching!
@@oldjohnnyrude8404 it runs great awesome little motor. There is a coat hanger looking thing that runs from the power head to the leg. I believe that is the rattle. Mine does same thing
That thing flies. Looks like a new Speed record.

joe cote hey joe. I have the same problem. Idk if the choke works at all. It has a really hard time firing up. Takes lots of pulls n hard to keep running. So a rag helps?
The choke doesnt actually "choke" it like a typical engine, when you pull the lever to full choke it actually depresses a plunger which injects a shot of fuel into the carb, at the same time it pulls a lever which advances the timing to increase the idle rpms. The timing advance is also held in the half choke position...kinda a mess
@@Nicky_Pin_It aka a primer
How fast do you GPS on that 14 footer with that?
Hashirama Senju with the stock prop which I'm running in this video, I'm going just over 25mph on GPS. I'm sure it can take more pitch and go faster. It has no problem reaching full rpm.
@@oldjohnnyrude8404 what spark plugs do you use in it ?
@@cmj2956 I have Champion surface gap plugs in it now, but I may be changing them to conventional plugs. I'm not really happy with the surface gap plugs. Thanks for watching!
I have the same motor. And they all have that weird tick like something's lose in then
Which tick? The clattering rattle while its running? That is strange. I really cant find anything loose but it still rattles like that. It runs great and has lots of power but it is rattly. The clicking when I went onto reverse was because I changed gears too slowly. I really prefer a separate shift lever to having the gearshift built into the turning of the tiller grip. I still like this motor though. It is a screamer. Thanks for watching!
@@oldjohnnyrude8404 it runs great awesome little motor. There is a coat hanger looking thing that runs from the power head to the leg. I believe that is the rattle. Mine does same thing
