I just picked up a starcraft fm 160 with a 1982 50 hp merc. I did a compression check on it and all cyl. read at 70 lbs psi. I know this is low but why would all 4 cyls read the same? Should I be worried or do you think putting oil in the cyls would help. The boat did sit about 2 years. What I'm thinking if the the motor was no good I'd have a couple cyls high and 1 or 2 low.Thanks
