I cannot thank you enough for your video. After numerous calls, repair quotes, and endless frustration, you explained beautifully what the problem I was running into. Thanks to you, a quoted $1500 repair wound up costing me right at $250 in parts. Thank you so much for this video.
I am so glad you showed the lower end of the shifter rod. I had it turned around BACKWARDS! None of the many videos that I watched explain that the shaft can be 180° out. CAUTION: notice the dog leg shape as you pull the shifter shaft!
Glad someone makes vids for us regular people. you mentioned that sometimes the reverse works out of the water but in the water with the pressure it might slip, what would cause that and how would you fix it? That's my problem.
Thanks for the brilliant video. just drained the leg oil on my 78 evinrude (serves me right I know!) and it was a yellow creamy color (water in there I assume). I have a spare engine so will pull the gear case and prop from that, keep it on the boat and replace the seal on the current one for now. Such a good video! Well done and thanks again.
thank you for posting this. our 98 evinrude ocean pro just stranded my folks . and they told me the boat ran great but they heard a clunk and it was done. and it was been clunking into gear . so I guess need to inspect the gears and that cam .
It got to them and ruined them lol . There are holes by both intakes and oil dripping down them . Luckily we found a used lower unit. So it should be on the water soon.
Brilliant information, my engine wasn’t going forward, just into neutral and reverse, took the gearbox apart n fixed what I thought was the problem but after assembling it back it now goes into neutral and forward but not reverse, I’m starting to think it may be something todo with the shift shaft?
And how do you pull the pinion gear off the drive shaft so that you can change out the drive shaft seals along with the shifter seals to do a complete reseal on the lower unit? What would cause the lower unit to only engage in drive but not reverse?
Dang! This is the closest thing to replacing the shifter cam. Great video. I was taking the lower unit off my 87 40 hp mariner and broke the shaft at the bottom where the roll pin goes in. BONEHEAD MOVE! Still trying to figure out if i want to attempt it or not.
Hi there. Very informative video. I have a small yamaha 8hp and the propeller has 1/2" movement left and right when in gear so is this normal or would it be best to chang the dog. Many thks
Best hands down thanks brother was about to throw back together and just not have reverse.But that could cost a man his sail boat going threw the coral reefs and such..Thanks from sailing catamaran vessel No Problem .Have to start starting these motors more after all this work.Do you have any videos on pulling a power head?Have to replace shift cams Yamaha 25 long shafts..
Hi bud great video , have an older 2 stroke 15 hp goes into forward and reverse but after idle won’t pick up speed but reverse works ? Dog clutch teeth gone or broken ? You’re thoughts cheers
Huge help, thank you! On your last point about ordering new parts: would you dissuade someone with little experience from fixing broken gears in the lower unit? The unit is 75hp and my goal is to restore it, if possible.
If you can find the proper service manual for that unit you will not have a problem, otherwise it can be tough with a few parts that may not make sense
Where did or can I get those parts I live in Alaska a whole lower end basically needs to be replace the whole gears and there’s a exploded Matic is loud which damaged some of the threads I could probably save the threads with a chase
Really helpful vid thanks. Just subscribed. My yam 15 2t is stuck in forward gear. Is it possible the shift cam in lower unit has travelled up 2far and can't travel back downwards?? Many thanks.... jj
Thank you for the great video. I did not catch the kind of motor you were working on. I have a 2015 20hp mercury 4 stroke (rev on the handle). Goes into reverse fine but when I put it under load or rev it up, it comes out of gear. Would you think that it is a dog clutch problem or an adjustment problem? Thank you for any advice you can give me.
I have a 1997 nitro with a 150hp nitro tracker engine , when I shift to go forward it won’t go it go in reverse can you tell me if is the shaft that when bad
Excellent video I was wondering do you have to take the lower part off to replace that Shaft or that reverse mine is real hard to go in reverse and I hear a clicking noise
I have a 1993 4o 2 stroke Tahotsu can I replace the shafts bering below water pump with out taking it to a machine shop ,and can you tell me why my shims wrapped around my bering and ruined it.? have you ever herd of this ,
I am having problems with getting out of Forward back into Neutral. Have you ever come across this. It does seem after the motor warms up and/or if I mess around with the trim. Have you ever seen this issue and if so do you know how it can be fixed?
Thanks, I have a 2006 Mercury F25 EFI and found this video after I recently discovered water in my lower unit oil. While this video is very helpful in showing me how to dis-assembly and reassembly the lower unit, my question has to do more with the seals. If you know, is it normally only the seal on the prop shaft that needs replacing or on the driveshaft as well? I'm doing the work myself and want to do/get it right. Any thoughts or suggestions would be greatly appreciated. Thanks. Great video!
My Yamaha 6hp gear lever is stuck stif and is very hard to shift from neutral. Is this a problem in the lower unit or is that the lever need lubrication at the top handle ? Is has been like 2 month I don’t used it. Just run it today , everything runs good but that
Excellent video. I just replaced the water pump assembly on a 1998 Mercury 9.9 ML kicker. In doing so I had to remove the shift rod to replace the lower pump housing. FYI, I have a remote throttle and shift lever if that makes any difference. After I buttoned everything up it will shift into neutral and forward but not reverse. Also, when in forward, the prop still spins, as if in neutral, but clicks. I obviously didn't get the shift rod back in correctly, but I'm not sure what I did wrong. Any suggestions on how to fix this would be greatly appreciated.
Where the shift rod joins together in the middle is just probably a little out of adjustment. Undo that long brass "sleeve" bolt and try adjusting with a few threads inbetween the rod ends. This will allow the shift rod to travel down farther, put the gear case into reverse.
Thank you for the quick response. However, my shift rod is a one piece unit. The cam/shoe that engages the dog is threaded on and that is how you adjust the length. I thought I got it threaded on in the same position that it was prior to installing the new water pump, but maybe I didn't. Question, which way does the angles portion of the cam/shoe face? Does the angled portion face the dog or does it face the front of the gear housing?
Good morning I have a quick question I took mine out this same piece and when im trying to put it back is not going in all the way im missing like a 1/4 to go in all way and this is in every gear i even remove that front piece that looks like a bullet to see if it was hitting something and same thing the whole thing is not going in all the way in gear i hear the ratcheting i even did it in neutral and nothing play with it a million times and dont understand what im i doing wrong i dont see anything else to this i was hoping you guys have some tips or some tricks to this thanks
When i bolt the propeller housing/seal back on, it l leaks. It didn’t leak before, but now some lube drops out the bottom bolt. I made sure to torque the bolts down little by little back and forth to insure even tightening; any thing i could do differently?
I have purchased a bass boat with a Johnson 150 fast strike and it will not Engadge into gear from my under standings it seems like you could deffinitley replace it pretty inexpesively instead of purchasing a brand new lower unit thank you very much !!!
Thanks for the awesome video. I have a 1995 Mercury black max. Oil is coming out of the lower unit. The gear oil plugs are on tight and no leak from there. Do you think oil is getting passed the seal and how you I replace the seal?
I changed my lower unit oil this week due to a unusual sound coming from my 1996 40hp merc.Almost the same as a lifter tick in a car engine.After draining the gear box my drain plug had a couple pieces small but chucks of metal more than the usual wear and tare shavings.Does it require any special tools to rebuild a lower unit?
ıt s a great video help a lot my problem is after ı put back evirithing if ı do forvat and turn the propela it s make click tun and clik is this normal ? thanks
hello, i need help hopefully you can assist. i took of my lower unit but i dont remember if i had it in forward gear or neutral when i took it off. now, i reinstalled the lower unit connected all the wires but now its like the battery is dead but i tried it with three fully charges batteries and it still wont start. i turn the key and nothing not even a noise at all or makes an attempt to start. any suggestions
Nice video. When we were driving our outboard the other day in forward the engine started making loud noises. It only happens in forward, reverse seems fine. I am thinking it is the forward gear or dog attachment for forward. How would I go about getting the forward gear out? Do I have to take the whole lower unit off to do that? Thank you
Hi, nice video! Been searching for an instruction video how to dis-assembly an older lower-unit (like 1985 for example) that has been running in salt water many years. These bearing carriers can be really stuck to the lower unit and will not easily come out... I have not found any video on how to do the job...
Maybe the prop ,iwas using an aftermarket prop on 9.9 4 stroke yamaha an it was making a nocking noise on full speed only,and dit not know what it was till i replace the propeller for an original,cost more but that solve the problem,may want to try that good luck.....
I have a 2018 Mercury 150hp and hit a rock bar. The whole thing shakes when shifting into F or R. I was hoping a new prop would fix it but no. Most likely prop shaft?
Thanks for good explaination vid. I have a 75hp merc outboard....I just tried to get my pontoon boat ready to launch finally! Noticed I made a fatal error not being familiar with outboard engines (new to this game). I left my engine in the travel position (prop pointing towards sky) all winter. Water got into the lower unit and froze of course, expanded and broke off the bolt flanges on the lower unit prop shaft bearing unit. So I ordered a new one from my marina. When I install the new one, I assume I should grease the prop splines. I will get new seals for the new unit. Anything I should be aware of when reassembling?
How did u turn out with this was it pretty straight forward? My stepdad has done the exact same thing to his pontoon boat I'm going to tear I down today for him
Had my boat out going up river and forward stopped working sounded like some rattling but reverse worked fine that’s how we got back home, any one know where I should start
Anyone know of a video or would like to make a video on how to fix a 1996 Yamaha 25 horse 25Elhu Lower unit. Basically have to rebuild mine after a sheer pin fell/broke (somehow bought the motor with out reverse and thought there was something wrong with the linkage only) in between gears and chewed up and destroyed all the splicing on the gears. Thanks for the help.
I have a question. I'm trying to fix this myself because it's really expensive to take to shop I have a 90 hp Mercury year is 2000 and I was running it on the lake one day and it just stopped and went really slow. I thought i had spun the hub but it was fine once I removed it to check it and so I think the problem might be inside the lower unit. Should I just buy the whole thing or what. Plz reply thxs
What would be the reason for the gear/ drive to be going counter clockwise in forward position after changing the impeller? Its a hand driven Mercury 18xd outboard (1986) approx. So turning the hand shift to forward it's going in reverse. Frustrating. Right hand propeller.
I cannot thank you enough for your video. After numerous calls, repair quotes, and endless frustration, you explained beautifully what the problem I was running into. Thanks to you, a quoted $1500 repair wound up costing me right at $250 in parts. Thank you so much for this video.

Thank you! Very informative!
Informative, and well presented
Good explanation.
Good video , made sense and concise .
Awesome video
Well explained sir 👌
Can you do a full video showing the complete teardown and reassembly including shimming the gears and water pump and measuring the gear backlash?
These are great videos
knows about boats too what a pilot
Thankyou. Probably saved me 3k.
Thanks...this video was a big help.
Glad it helped!
You should do a video on how to put the pin in if it falls out
complete explaination.greet fr Malaysia.thanks
Excellent video! Go Buckeyes!
thank you for posting this. our 98 evinrude ocean pro just stranded my folks . and they told me the boat ran great but they heard a clunk and it was done. and it was been clunking into gear . so I guess need to inspect the gears and that cam .
Sounds right, probably water intrusion has gotten to the gears
It got to them and ruined them lol . There are holes by both intakes and oil dripping down them . Luckily we found a used lower unit. So it should be on the water soon.
Thank you for the video. helped me a lot

hi great vid i have 2002 johnson 35 hp what would cause it to stick in reverse? thanks for any advice
And how do you pull the pinion gear off the drive shaft so that you can change out the drive shaft seals along with the shifter seals to do a complete reseal on the lower unit? What would cause the lower unit to only engage in drive but not reverse?

Hi so nice thanks for your help is this same to bigger engine like 250 hp
Taking out the drain screw is very important! It will not come apart otherwise.
Be nice if you reply to some of these questions
Thank you for the great video. I did not catch the kind of motor you were working on. I have a 2015 20hp mercury 4 stroke (rev on the handle).

What causes oil leak from weep hole in lower unit
thanxs
if the bearings are bad can you tell by how the prop spins? how can you tell?
Does it lack the power it once had?

Hi I have a Honda 40hp .I have a problem which when I turn the gear to neutral the prop does not turn .can you help pls?
nice🎥 i hve a 96 115 evinrude, rev wrks fine, frwd revs before engaging. Gears or hub? and are the lower unit removals the same in some way, thks
That doesn't sound like a lower unit prob. sounds like your control box is out of adjustment. take a look at adjusting control cables
I did this exactly on my Tohatsu 20hp 2013, now I dont have nuetral or reverse. What did I do wrong ?
My Mercury 9.9 Propeller still rotate CW in forward with the engine off. Is this normal.
Would the procedure for replacing the prop shaft on a 2012 Evinrude 115 ETEC be significantly different from what you show here?

How do you change the lower unit on a 7.5 mercury 2 stroke
Ive never did it b4
Nice video. When we were driving our outboard the other day in forward the engine started making loud noises. It only happens in forward, reverse seems fine. I am thinking it is the forward gear or dog attachment for forward. How would I go about getting the forward gear out? Do I have to take the whole lower unit off to do that? Thank you
Could be as simple as adjusting the shift cables or shift rod, otherwise yes, time to drop the foot and have a look inside.
01:00 Yeah... RIGHT!!
why would my forward skip? no damage to gears or pinion
what is a scutter, scuffer ? And what does it do?

Hey what could cause a knocking noise on the lower unit?
Maybe the prop ,iwas using an aftermarket prop on 9.9 4 stroke yamaha an it was making a nocking noise on full speed only,and dit not know what it was till i replace the propeller for an original,cost more but that solve the problem,may want to try that good luck.....
I did this and when I get to the lake the boat only forward, no neutral or reverse. Im no getting it to fit in right, can you help me?
I have a 2018 Mercury 150hp and hit a rock bar. The whole thing shakes when shifting into F or R. I was hoping a new prop would fix it but no. Most likely prop shaft?
Sounds like it.. how much did that set you back if you don't mind me asking
Thanks for good explaination vid. I have a 75hp merc outboard....I just tried to get my pontoon boat ready to launch finally!
