Compression low?

Post by fish2keel »

Hey guys. Found a 70hp evenrude from 1987. Commission check says 115-105-115. It does run. Should I be concerned?

I'd pull the head an investigate.. might just be a head gasket.. if the cylinder looks good, I'd put a new head gasket and run it.. but before doing that I'd go over all 3 carbs, the center one might be running lean.
It's on the borderline of being concerned
