I have the carburetor model ocean pro I'm putting up for sale. I road in the boat last season (it was on a friends boat and ran good) , it's on my test stand now. The motor seems to run fine barely starts to turn over before it's running and idles smoothly. I took a compression test as a selling point and had a low of 87 and high of 94. I'm getting different answers when I try to find the acceptable compression for this motor. Anywhere from 60 to 120 psi. Your thoughts?
