I'm new to the forum posting wise.. I recently bought a 97 seadoo gti that ran out the water but would die in the water. After looking I noticed gray fuel lines so I changed those and new spark plugs, drained old gas and rebuilt carb. I just put it in the water and it ran rough at first then wouldn't crank back. After I got back to the house I took spark plugs out and noticed water on them. Then I turned motor over and quite a bit of water shot out possibly mixed with a little oil.. am I screw or could someone maybe point me in a direction. Could it b possibly a head gasket? Even when I took the carb off my intake gasket was soaked.. so it my motor done and need rebuilt
