I have a 120hp IB Mercruiser motor. I see that 2 of the 4 plugs are leaking water around them when the motor is running. No water is getting in the oil nor the cylinder head. I am being told that it could be a water jacket problem. If this is so do I have to replace the head or is there a water jacket gasket that needs to be replace. This motor is on a 1977 Renken boat. Any advise would be helpfully.
