I just bought a 1973 Johnson 65 hp that had being sitting for a couple of years on a boat. I bought it for $400 but the control box was all tore to hell and back! So I have no control box for it.... By the way it says it is a powershift 2, but has 2 cables running to the motor and a red plug at the end of the wire harness coming from the motor so I should be able to use any omc- Johnson control box and wire harness for this motor right? Anyway the compression was 120 psi on all 3 cylinders. Was just wondering if this is good compression for this motor. My Evinrude 60 horse 2 cylinder had 150 psi on both cylinders. So is 120 psi good enough for this motor? Thanks
