Re: 1973 Evinrude Mate 2HP Issues

quote Fisherman6:

By chance was there an issue with the lower crank bearing / seal was leaking on the original case? I have a 1976 Evinrude 2hp with a bad lower bearing unit. It has decent compression, but it won’t even fart on a prime charge through the intake due to insufficient crankcase compression. It will pop a little and give a little smoke with a charge through the spark plug hole but that is all. Just curious if this was ever checked.

Hi Ben, actually I used the same lower bearing unit from the original motor as the parts motor was missing both crank bearings. But that thought had crossed my mind. I ran it in a barrel for awhile under varying speeds and then compression tested again. And now its testing around the 110psi mark. At this point i’m pleased. Just about double what I started with.
