Chances are you will not see anything remotely "accurate" as there is great variation between gauges. Best you can hope for is to have the motor be over 100psi in both cylinders and no more than 10% variance between cylinders. This is why you’re not likely to find published compression readings in any OMC produced shop manuals.

Actually, a brand new motor will likely have LESS compression as the rings are not yet seated in their bores and haven’t gone through any break in period.
