I just had the head gasket replaced on my 1996 112 Johnson by my mechanic. Reason being is I had found some water in the #4 cylinder. The mechanic said he ran the motor after replacing the head gasket and did not see any indication of any more moisture. He told me to put the boat back in the water and run it. <br /><br />If the moisture comes back to that cylinder what could the problem be?<br /><br />Thanks
