check your gauge on anything over 150. 150 is a new motor with 9.4:1 compression (and is what is in the manual)

with the serial number of your motor you can get the volvo manual specifically for your motor

or you can look on http://boatinfo.no/lib/library.html

Wow almost a year since i posted! I found rot when installing the motor spent the spring and summer fixing that and reinstalling the motor. it's been in the water once for a short cruise. It's so worth the effort. A couple of issues still. The starter is dragging. I had to use the original starter due to flywheel size. would love to use the small diameter starter that came with the 5.7. does anyone know if there is an offset bolt nose for the small starter?

Yes they make PMGR starters for both 153 and 168 tooth flywheels. About $75
