I am going with my brother to look a his potential next boat this afternoon. The boat is powered by a 1999 Johnson 250hp V6 outboard.
I am going to give it a quick inspection and compression test. I am wonderiong what I should be looking for as far as conssidering this motor to be healthy.
I know that all cylinders should be relative to each other but should it be in the 120-150 psi range? I only ask as I looked at a 225hp last year that was a good runner at about 95 psi on each cylinder. I passed on that one because I thought those #'s were low.
