We have a kawaskai 650ts. Ran fine last summer. This summer it starts great--idles fine---runs at low speeds fine-- but when you go to open it up and plane it out, the rpms increase - but the jetski doesn't move any faster. Any ideas what could be the problem?????

I would check the water intake on the bottom of the boat. If it is clean then check to see if the impellar is damaged or not turning with the motor. If you can get rpms then the problem can only be in the jet pump.
