1990 evinrude 150 HP compression ratings

[crestlinermusky]

Hey there, thinking of upgrading the boat to a 1990 aluminium 18' Crestliner V180
The boat has a 150 hp with the VRO disconnected and I'm told it runs fine.
What are the compression ratings for this motor. I know they are lower than a V4.
I am planning on seeing the boat this weekend and would like to know what the ratings are.

The following is what I have always encountered, right out of the box, or years old but in excellent condition.
Brand new.... Starboard bank = 95 psi...... Port = 90 psi
