1995 Johnson 90HP

[MannyC]

Hey guys, I'm new here. I have a 1995 Johnson 90HP (J90TLEOR) on the left side I have 110 PSI on the cylinders and on the right side I have 90PSI on the cylinders. I'm not too familiar with this engine. Is this normal for this engine or does the PSI on the heads need to be more?

Thank you.

90PSI is low, all cylinders should be over 100PSI and within 15% of each other.
