Evinrude Mate 2 HP Driveshaft

[whywhyzee]

I have a 1972 2hp Evinrude Mate. The oil seal below the impeller has worn a groove in the driveshaft. There is also oxidation/surface rust in that area of the shaft. I can't find a speedi sleeve for that small a diameter (10.8 mm). Are there sleeves available for this? Any suggestions? I'd like to keep this motor going.

does water get in the GC...?

maybe best to look for a spare shaft or just change the oil mid season if it does leak
some welding shops can " blast" weld" the groove away $$$$ but not very cost effective on a 50 y old motor.

oil is cheaper

You could try replacing the driveshaft seal, and not seating it all the way, so sealing surface is above the groove.. this has worked for me in the past. Do a quick pressure test before filling.
If really bad, find one at salvage: https://forums.iboats.com/threads/salvage-yards-by-wilde1-verified.428012/
Good luck!

Should be easy to find a good replacement shaft.

I've been keeping my eye out for a parts motor. When they come up for sale they sell really quick. I may take it to a local machine shop to see what they can do. It has some sentimental value to me so I don't mind spending a bit. What I was really hoping for was a speedi sleeve type repair, but I can't find any sleeves for this small of a shaft.

I'm not sure there's room to do that with the impeller right above the seal. I'll have to have another look.

What I have done in the past is use old driveshaft ( have many of different sizes ) and machined my own thin wall sleeves ( 0.010" ) so original seal can be used..----Your location ?

It could be spray welded and turned back down to spec if you can find a good machine shop.

I'm in Ontario, Canada.

I'm thinking this might be my best bet.

Thanks! I'll give them a call Monday.

Evinrudeparts.ca did not have anything. I took the shaft to a local machine shop to get their thoughts on it. He said welding and machining was an option but the welding would warp the shaft, which I didn't want. He ended up polishing that part of the shaft. It came out great. I'll update the thread after testing it in a tank.

Great news.
If by chance it doesn’t work out.
There is a difference between welding and spray welding.
Spray welding is considered a cold process and should not warp the shaft. Hopefully the polishing will work out for you.
Best

Good used driveshafts are not hard to find.----The same shaft was used year after year.
