In this video I replace the dog clutch on a Tohatsu 40C. This involves removing the prop shaft and replacing all the springs and selectors as well as the dog clutch itself.

I believe you are wrong. the dog clutch was in correctly with the deeper dogs toward the forward gear. On the OMC dog clutches it is marked PROP SIDE, and those dogs are the shallower ones.

No problem with my dog clutch, just couldn't figure out how to remove the "doggone" thing to install on my new propeller shaft. Yours was the only video that actually explained in simple detail, actual removal and reinstallation. The spring's function as a pin retainer never occurred to me. I just saw a spring sitting there that seemed to serve no purpose. With your instructions, I swapped out the dog clutch from my broken prop shaft in mere minutes, saving me big bucks for sure! Can't thank you enough! Thumbs up, and subscribed!

@Danger marine, I have a 2001 25 hp Tohatsu. I recently did a seal replacement on the prop shaft oil seal. Reinstalled the prop shaft and housing along with everything else. I then took it out on the water to test and when I would go full throttle then eased down to put the engine in neutral; it would get stuck around idle speed. When I would try to knock it out of gear it seems the clutch dawg would try and bounce in reverse. Just wondering if you’ve ever experienced this or have any tips on what went wrong? maybe something with the plunger or clutch dog came loose?

you saids that the "natural position the gearbox wants to be is in forward". that made me curious as to how I should store the motor. When not in use, would putting it in forward gear increase the longevity of the spring? Im assuming it really doesn't matter.
@DangarMarine
@DangarMarine 7 жыл бұрын
It's a good point you make. Having it forward would allow the spring to relax a little but I wouldn't lose any sleep over it, I doubt it would shorted it's life much.

Just wodering about the slight play on the gear selector cable and also the play the cables' plastic shaft (motor end) has within the bracket the shaft sits in. Having trouble with the cable pushing fully into reverse gear and also the adjustments. Wondering if this motor has the connecting nut between top and lower unit gear selector and could i get the more adjustment there? TIA..

Great video Stu. I used to be intimidated by the mysterious inner workings of a lower unit. Now I see it's not all that bad. I might have to do this job on my Yamaha 150 eventually. The idle was set at about 1500 RPM when I got it. It would clunk loudly into gear until I lowered the idle. Who knows how long it was previously run like this. Probably have some wear on these same parts. Btw, I think the clock above your workbench needs a new battery. Second hand seems stuck. 😉

Used this video to help me replace the prop shaft on my 15hp yammi. Previous owner neglected to tell me about hitting something, I tried to bend and wack it back in round but a new shaft was cheaper than lower end. A prop nut and two 10m bolts the shaft came out with bearing gear assembly, did not to drop lower end. Used your video as guide on how it functions for assembly, fastest repair so far. I think a lot of owners are afraid of this task, maybe put a video together off an old lower end showing this sequence. Thanks again, I'll share your vids with my dad in Fiji next time I visit.

Hi Stu Awesome guide - how to - Video once again i applaud you. Keep them coming. Question for you. How can i check a lower unit is working when it is not connected the power head. All i have is the lower section ie gear box selector shaft and drive shaft. I was told it was working but is there a way to make sure it is before i go and fit it.The unit is an old Suzuki DT40 2 stroke. Hope you can point me in the right direction or maybe do a video on the subject. Cheers again mate from bonnie scotland Andy

Hey Andy, the trick with gearboxes is to select each gear and then rotate the driveshaft while trying to stop the prop from turning (be careful not to cut yourself on it) What I find with gearboxes is that you can select a gear, turn the drive shaft and the prop will turn, but as soon as there is a bit of water pressure on the prop the dog clutch will start to skip because it is only barely engaging. I would also drain the oil to look for water or metal fragments and do a pressure test on the box to makes sure all the seals are good.

Great video! The engine on our 2006 15hp Honda was revved really high then put into the forward gear. A few seconds later we heard the gears grinding and crunching together. I have a feeling I will need to perform the same type of service on my motor. Big thanks for putting this video together.

Excellent video that explains the shift mechanism and how the fwd/rev gears engage (or not) on the prop shaft. I am working thru a similar issue now on a Force 120HP motor. Broken shift cam and stuck in reverse. Plan today is to remove the pinion nut to get at the shift cam. Since the motor is 20 yrs old, I have decided to replace the clutch dog and pins, etc rather than both fwd/rev gears even though they show some wear on the contact faces.Wish me luck.

I have a Honda at the workshop at the moment with a similar problem, I'll wish us both luck. :)

Quick question - is there a method to prevent scratching the drive shaft while removing the pinion nut? I was planning to use a pipe wrench but concerned about gouging the shaft. Also, are pinion buts standard thread or reverse threaded?

My 96 M25C2 was jumping out of gear at high speed forward so I decided to change the clutch dog. Got all new parts just like in the video. Put it together just like the video. But can’t get it to shift into reverse now. Yes. I put the dog clutch in with the long end towards the propeller end. This model has a ball between the push rod and the clutch spring plunger. I tried it without the ball and it then shifted into reverse and neutral but not forward. Any chance the push rid is wrong? Part 3C8642331

Hey Dangar, I am having trouble getting the prop shaft out. I have removed the bearing housing and lined up the gear selector in neutral and it just wont budge. It is a 90hp yamaha 2 stroke. Love your videos by the way. Cheers Alex

Hey Stu, first time I’ve taken bottom end apart on a 2011 Yamaha 30 4 stroke. I cannot find which is neutral on the shif slope and putting prop shaft back in. I looked at you’re other vid, but didn’t show the spot to put the shifter in neutral. Appreciate the help. I see indents but can’t figure which one to use. Thought something went wrong inside, turns out it’s prop chatter. Ugh

Neutral is the midpoint on the wedge, halfway between forward and reverse.
