Hi everyone. I recently purchased the above referenced used ski, and took it out on the water for the first time yesterday. I could only get a top speed of 35 MPH, however, the engine is 120 HP. Shouldn't I be able to approach speeds in the 50+ MPH range? Otherwise, the ski runs great. Any ideas on what the cause could be? Could the speedo be wrong, or might there be a speed limiter set on the ski's computer, or some other mechanical issue? I'm a newbie here, so any thoughts / ideas would be appreciated! Thanks! :dunno:

sounds like a jetpump issue, you are turning good rpm but your getting any speed. check the impeller and wear ring for damage or blockage in the pump.
