I'm brand new to pwc's.bought a 99tigerskark ts770l. First time out the power was very weakafter10minutes. The engine compartment was filling up with water.obviously the bilge pump want working.after I got it home and ran it with the hose the exhaust was dripping water and it appears to be leaking water from a flange on what I am guessing is the exhaust manifold to some sort of expansion chamber.this can't be normal but I know very little of engines.any thoughts?
