I'm changing my impeller on my 15 hp 2 stroke evinrude. I also noticed that where the shift rod goes into the gear case, there is a small amt of water that escapes through there. Being fairly new to outboards I didn't know if that was normal or not. I thought it was not normal. If not, how do I fix this problem. I figure it would be something easy to fix, like a bushing, or o ring that I can replace when I replace the impeller. See attached video to see what I'm talking about.
I was thinking that replacing parts 25, 26, 27 from the following schematic would fix the problem. Any suggestions. Where is the best place to buy these parts?
