[diesel1960]

Have inboard GM 350 (Volvo Penta AQ290A)
Did run compression test on this engine ,not sure if results are satisfied :
cyl #1-150psi
#2-150
#3-150
#4-140
#5-130
#6-150
#7-148
#8-135
repeated test twice to confirm,need to run one or two seasons of this engine before rebuild.

Nothing wrong with those numbers... High enough to be happy, and only 20psi variation, within spec.
