Hey everyone need some help from some guys that have been through a few older ski boats. to cut a long story short got water in both back pots in brand new 350 only done 22 hours, which i thought was strange to do both sides but took it home compression checked it all were perfect, so i pulled exhaust manifolds off and inlet manifold pressure tested them no leaks, so put it all back together new gaskets checking everthing as i went hooked it up to the water at home and fired it up did the timing running like a dream turned it off an on a few times all good, took it to the river did a couple wakeboard runs then turned it off in the middle to swap boards went to start it agein an hydrolock pot 1 and 2 only, pulled plugs out turned it over empty it out and started it agein running perfect HELP ....
