Friend of mine bought his old boat back from the guy he sold it to. Has a 1984 35hp Johnson on it.
The guy told him the motor would start up and idle great, but wouldn't run under a load.
So, my buddy gets it home and cranks it right up, and notices there's no water coming from pee hole, so he shut it off.
He decides to check compression. He said he got 140 psi on both cylinders, but the pressure dropped down to 60-70 psi almost immediately. Does this mean anything? He has it in his mind, that the guy ran it hot and toasted the cylinders, but I wouldn't think it would fire right up and idle like a champ?
