johnson 150 compression

Can anyone tell me the proper cylinder compression for a 150 johnson ('89).<br />Not scared, just curious.

Howdy, EGT.<br /><br />Each cylinder should compress over 100psi and all should be withing 15psi range. If all cylinders are close to each other, lower psi is acceptable.
