Re: More Mercury 110 questions

So, I am getting through this lower unit a piece at a time. A lot different than OMC’s, that is for sure. I can see why these things go like they do with all the extra bearings as opposed to bushings. It has to make a difference in the HP that makes it to the prop.

Anyhoo, as Frank would say, I have a question about the shift shaft in the lower unit. The upper part of the shaft that resides in the exhaust tube has quite a bit of rust/pitting, etc on it. This extends right down to about where the shaft seal rides. I don’t think it will leak, but want to prevent it if possible. I can build up the bad area with JB Weld or something, but it appears that I could just flip it end for end and put the "bad" end down, and the good end would be up. The only reason I ask before I do this is that the splines are cut a bit longer on the end that goes in the upper shift shaft coupler, than those that go to the shift dog thingy in the gearcase. The snap-ring is exactly in the center of the shaft.

Anybody ever switch one of these around?

Thanks for listening.
