Hi i have had my ski for about a year now and haven't had any problems other than i cant gas it off the line it will just bog down so you have to feather the throttle then it will go but i have no idea what it could be? I also flipped it for the first time and i got on and started it and instantly new there was a problem just by the sound. i checked the pressure and the front is now 80 Psi and the back is 115 checked it the day before and it was normal so somehow the water damaged it i think.
