Hi everyone. I just purchased a checkmate boat with a 1990 115hp mercury outboard. I am new to boating and I would like some information and tips on how to keep this motor running top notch. What should the compression be? top rpm? Anyone that has some tips please post them. Also what kind of prop works good on this motor? I am mainly going to use it for skiing. I did a search and didnt quite find what I was looking for. Thanks in advance!
