Having a problem with my 04 3d 787. Hesitates when you give it gas, or doesn't want to take off right away, and if you go into a turn at full speed the rpm's will decrease even if the throttle is fully pressed and the ski slows down. It is not the throttle position sensor, crank position sensor, voltage regulator,or spark plug wires. All these items which the seadoo dealers said were the problem, but clearly weren't, have already been replaced.l Any help here would be greatly appreciated. Thanks
