No power down low

[Tkovac86]

Hi I'm new to jet skis and first forum post ever
I recently purchased a rxdi seadoo.
No issue just lacked a bit of power and bogging down when whipping it around
Changed out the wear ring as it was a bit worn and also rebuilt the rave valves
This was a huge power increase and gained close to 15 km/h
The next time I took it out it ran half the day then started cavitating around 10km/h with the trim down it wouldn't go anywhere
Worked out if trim was up it would get past the cavitation and be fine no power lose issues
I found the wear ring was toast.
This has since been replaced along with pump rebuild and a solas 15/20 impeller and still same issues.

Please help wife's gonna cacerate me soon

You could have a carbon seal sucking air around the driveshaft.

It is also possible you need to reseal your pump and/or rideplate and intake grate with silicone.

Any place that can suck air into the pump can cause your symptoms. If your ski keeps eating wear rings you have another issue.

Thanks
I was going to do the carbon seal as this was my thought on the cause.

i didn't think cavitation would be the cause of the wear ring damage. Any suged

Any suggestions on what would be the cause
