    2007 STX-15 108 hours Pump Shot?

    Suspected Pump failure...
    2005 STX-15 with 108 hours freshwater use.
    So I went for an extended ride on my 2005 STX-15 with my kid on my 2006 STX-12. We were about 2 hours out when I first noticed that the vibration was getting worse and louder so we headed for home. About 1 hour after turning back the STX-15 started to vibrate badly and lost some of it's power. I was still an hour from the ramp so I slowed down and limped home at a smooth and continuous speed. It used to do 92km/hr but by the time I got it back to the ramp it was doing 40 km/hr on reduced throttle. There was never an overheat and the check engine did not light. The tattle tail ran steady so I don't think I did any engine damage due to heat.

    The STX-15 has always had a slightly different pump noise and vibration than the STX-12. I had been meaning to get into the pump to check for contamination but now it looks like I am into a complete rebuild. I can see the impeller has excessive clearance to the wear ring from the pump nozzle.

    There are no foreign articles or damage otherwise.

    I have done plastic wear rings on Seadoo but this looks a lot different.

    Advice?
