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.

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!

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.

(provided the parts i need are all available. and that damn dog spring will be a beastie). thanks again Stu

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 agree in only replacing the one gear, the tollerances are not tight anyway, and it takes ages to naturally wear the other gear out. Just use quality oil and decent intervals and it will live a long life. Nice purring tohatsu

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. 😉

@Condor1970 6 жыл бұрын

One thing I've learned is that as the dog clutch gets old, it starts chipping and leaving some flakes in the fluid. Especially if you use your boat for tubing and such, where you are constantly shifting into and out of gear through lots of use. These little flakes seem non-ferrous because they don't stick to the drain plug magnet. You can replace the clutch by pulling the prop shaft and not need a whole new outdrive, like a lot of guys will tell you.

@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?

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

@DangarMarine 7 жыл бұрын

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.
