I own a gprsvho conversion that I take out every weekend and never had a single problem, until yesterday. I went to fill up with fuel and opened the top hatch like I always do to see the tank as Iím fueling and when the tank filled I noticed a good amount of fuel rushing out of the check valve so I immediately went home and washed all of the fuel from my hull and pulled the check valve which seemed pretty loose where it connected to the tank but didnít notice anything abnormal other then that. Turned back around and put the ski in the water and it started and ran smooth as ever but when I got past the no wake zone and began to pull the throttle it seemed as if the ski was in limp mode and wouldnít even go fast enough to plane off. Anyone have any ideas what it could be?
