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:

what rpm is it turning at wide open.

Good question. I'm not seeing the RPM on the display. Just speed. Not sure how to check RPM...

After riding yesterday, looks like I'm running about 6,000 RPM's full throttle.

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.

Thanks for replying. I'll check it out and post the results.
