Do you have an exhaust tube sticking out the back of your ski or is it flush with the hull?well, I pressure tested the cooling and no leaks... so it's got to be the exhaust... I rejetted from 120 to 80 in sprayer, turned waterbox around (i had it it backwards but backwards made the most sense when you look inside. I also raised the box up about 2" off the bottom. I have considered a flapper and may still do that as this is a silly thing to deal with. This is my first lay down pipe and I had not even thought about it backing up. anyone got pics of their flapper? Im sure I can just buy one from an old Kawi but would like to see what yall did
