Hello, I just bought a 1999 GSX RFI seadoo and i think theres a problem with it. Today i was riding at the beach for a good 4 hours to test drive it for the first time. I noticed when i accelerate it takes time before it catches speed.. And when i put someone on my jet ski me... It barley as power.. i would accelerate fully it was smoking alot and it would stuggle to even go 15... And when i was alone it went maybe 55 But it should be faster cause my friend has the same stock jet ski and motor .. And there was 2 person on the jet ski and it was going faster then mines, me being alone on it. Is there something broken that i have to repair on the motor? to give it more power? At take off and maybe at top end. Hope you guys could help me out.
