what could cause water to get in bottom cylinder on my 2001 70 hp 2 stroke. It runs good until it gets warm then it loses power at wide open the throttle. I had a friend of mine that works on outboards look at it he took the bottom plug out and said that it looked like a new one, and he spun the motor over and water came out. He said that it could be a head gasket, cracked head or a cracked sleeve,an help would be appreciated
