1987 Force 125 Low Compression 65#s

[WILL23]

I have recently took my boat to our local repair shop to have some minor repairs done. The mechanic called me and said that I've got low compression on my #4 cylinder. He said the only thing I can do to save my motor is to re-ring (@$1500). My question - is this correct? Does anyone have any other suggestions? This is the only major problem I've had since i've owned it!

What are the #'s on the rest of the cylinders? I would try a decarb, as you have nothng to lose by giving it a shot. Mercury makes an aerosol product called Power Tune that I like. It may not be the answer, but it couldn't hurt. Good luck!

Thanks for the reply. They said the compression on the other cylinders were 131-135 #s EA. Where can I get this decarb?

Try NAPA they carry the de-carb you are looking for Deep Creep Sea Foam

unfortunatly im gonna agree with the advice of you mechanic.there are other reasons that would cause this but they will or should be repaired during the re-ring.such as a blown gasket.dont mess around with a sudden drop in compression.may quickly lead to other more expensive problems.you can do a re-ring yourself.not that difficult if you have a manuel.just takes a bit of time and patients.good luck.
