Evinrude 4425 interchange help

Postby twostroke » Sun Nov 12, 2017 1:24 pm

I'm restoring an Evinrude 4425 Sportsman, and I just finished disassembly of the foot of the lower unit and I found a broken part.

It's the Prop Shaft Bearing Assy, P/N 276321. I may be able to use a friend's TIG welder and repair it, but I also have a Evinrude Model 3012 that I'd be perfectly comfy with cannibalizing. Does anyone have the resoures to tell me if they're the same part?

As usual, any input would be greatly appreciated.

Thanks!
Jim

It doesn't look like it would work Jim. I just pulled the manual from Garry's Drop Box.

Thanks,Steve... I'll cross my fingers and see if I can weld it. Where it's broken, I can weld it with the shaft in it, so it's no problem keeping exactly in position.

Thanks again!

The 44223 Sportwin uses the same prop shaft bearing . . . :)

For what its worth - I've seen two other 4425's with the same problem. That casting is kinda thin in spots and seems prone to fracturing. My Dad's 4425 had this problem, he found it that way in the 1960's. at the time he just put it back together the way it was and ran the thing. It ran for years like that. In fact, it still is that way, I've never fixed it either, and I've known about it since 1991. Finding a second motor with exactly the same break on the same part made me think it could be a chronic problem. Now that you're reporting the same type of failure, I'm migrating from thinking to believing. I didn't fix the second one either.... and not because the part is not available, because I've got an NOS bearing carrier sitting on my desk not a foot and a half away..... just don't feel like using it.... yet
