All my books are for older engines and I can’t seem to find the info. 1996 15 Johnson 4 stroke. Just a good ballpark number as it was overheated a bit.

Good question for sure, don’t know if OMC posted numbers for the four strokes. I don’t think I have a four stroke book, but will check when I get back home…

As far as I know, only Chrysler published compression figures. . . 😀

Balance is a good starting point. What are your numbers?
