you may already know this, but if you don't it may be some help to you. the motor needs to be warmed up, for a true reading. let it run for about 10 minutes. make sure you have water to it, so it don't get hot. I just rebuilt a 90 hp, and it had 127 psi on all cylinders. I think 75 psi would be low.
