I am buying a boat with a 1999 Johnson 90 hp. What compression should I have at the cylinders. What common problems should I look for.
Thx.

Re: 1999 Johnson 90 hp

Id want 110 or more and they should be close to each other...many people say 10%

look for corrosion ...less the better...

look for missing stuff

look for damages props and lower unit parts..ie skegs cav plate ect..
