I think compression should be in 90-110 range and CONSISTENT across all cylinders w/in 5 psi....look at the overall cleanliness...hose rot...check lower unit oil for color (milky AINT good...indicates water intrusion)...too BLACK means too long since last change...clear amber is what ya want it to be...trim & tilt unit...take a hot battery to check that out...was it on a bass boat?...if so those guys generally run 'em WOT all the time, in fresh water, so that's the good and the bad there...hours??...controls??
