My boys are out on a trip this week and ran into some problems. They were on a flawless 4 hour trip when they arrived at their destination they noticed a hissing or helicopter like sound from the engine. When they made it to the dock the engine was running rough. Upon trying to restart the engine at the dock it tried to crank, tried to turn, but could not. Oil dipstick was not like a milkshake. Diagnosis being done now as I am not with them. Thinking manifolds (5 years old) What would make the hissing noise? Water in the cylinders?
