This is my first post...have a 1965 raw water cooled engine that runs great....however.....
I sail in Georgian bay...cold and fresh...and have always had some steam or white smoke / coming from the exhaust....however the boat had an older straight double walled exhaust pipe so in order to ensure that there were no pin-hole leaks, this spring I put in a brand new MM stainless water lift, all new hot pipes, and new exhaust hose....it all works perfectly.....but....the engine still steams. New impeller, no clogs in the intake, and the engine does not overheat...around 120-130 with a new 140 thermostat installed.
So the question is......does this sound like a leak in the manifold? Or something else?...A cracked head??
I read the threads whenever I can....great info source!!/
