water in the top cylinder

[mr crankypants]

Hey every one. I have a 96 challenger I know its a boat and not a pwc but its a single 787 last time was out on the lake it started missing limped back to the dock and the top plug was milky. At home I have treating it like a hydro lock seems like a endless supply of water comes out dont know where common leaks are in this case.where the exhaust meets the head it dose have a leak on the out side right below the rave valve.should I just get a complete gasket kit and do them all.or this a bigger problem.when docking last time the reverse cable bent and I only want to make 1 trip to the dealer for parts please help. Theres nothing like putting your boat in reverse and flooring it only to go full speed forward at the dock.

never mind pulled the head off today and found out the last owner or his mechanic was an idiot.the rubber seal around the piston was not there. now I'm dealing with the water in the crank case because this means its been leaking all 3 times on the water and will need a motor soon.whats seems weird to me is that it had 140 psi on both sides.
