Here ya go, first time I've ever checked the compression on this engine.
Port
112/3
110
107/8
Starboard
108/9
110
115
The compression gauge is in 5# increments, I estimated when between the lines. 112/3 is right between the 110 and 115. Yeah, I was surprised with the numbers. One of the wholesalers told me anything at or below 90 is a no-no.
