I have a 98 Yamaha 1200gp. It runs great. Besides the fuel gauge is stuck. I was riding today and i started to take off from a stop and it almost seemed like it was slipping. Wouldn't get about 10 mph at full throttle. Turned it off to check under the seat and couldn't see anything. Started right back up and took off just fine for a while. Then it happened again but I could slowly get the jet ski up to speed by just barely rolling on the throttle to about 45 mph at 7000 rpm. Turned it off and started it right back up and it was fine. Started hitting the normal 65 mph again.
