Help Needed on Boat Purchase: Compression

[Zara Spook]

I'm taking a look today at a 2002 V115. Any idea what compression numbers I should be getting for that engine?

I'm sorry it's actually a 2002 V130.

The readings may be in the 110 to 140 range, but what is most important is that each cylinder's reading should be similar within 10% of the others....if they were about 120 except for one cylinder about 70 or 80 then it could indicate a problem in the low cylinder....
