I have an old ski twin that I have recentley fixed up, was running full throttle yesterday and engine cut out. Smoke was comming out around plugs and head gasket area. I took off the head and checked cyl. black soot everywhere but no damage. rubbed oil on cyl. and put everything back together and seems to maintian compression. Took off lower unit and checked impeller, looks fine and water was comming out pee hole when it was running, one of the fist things i check before taking off. Any idea's on why its Overheating?
