The head gasket was changed and mechanic says there still is water in one cylinder. There is a fued going on between the lady owner and the shop. The engine is a 1986 OMC 5 Liter 4 valve, (305 c.i.). After the repair was thought to be a failure, the mec. followed the boat on the water to observe the exhaust. He then repaired something on dry land, but the problem still exists. Thus the FUED started.
