Ok guys here is what I have. I bought a 1973 Mercury 500 50hp outboard motor for 50.00 bucks that came with controls also. I panned on putting this motor on my bass tracker next spring. The motor has been setting a long time from the looks of it. I have the motor stripped down and got around to checking compression. The number 1 cylinder has 110 psi number 2 has 111 psi number 3 has 90 psi and number 4 has 110 psi. I know the number 3 cylinder is low but im thinking its not from damage of the piston or cylinder but just stuck rings maybe. I can put a little oil in the cylinder and it will shoot up to 110 psi fast. What do you think about this? I need all your opinons on this one please.
