    RXP 215 w/X Charger Cavitating

    I just purchased a 2004 RXP with 145 hours. The previous owner installed a 2010 X charger in it at 120 hours along with 42 lb injectors. Everything else is stock. Coming out of the hole, the ski is cavitating for a few seconds before it finally grabs and goes (hits 8100 or so RPM). Do I need to look into a different/new prop or should I be looking at the carbon ring as the issue? The previous owner purchased a Solas prop for it but never put it on and I didn't feel like dropping down the extra cash on it when I purchased it.
    Also from the reading I have been doing on the forums, should I look into replacing the washers on the X charger too?

    Yes, the wear ring is stock. Why would stainless make any difference?

    The stock ones dont hold up for very long at all. Plus with the power. The SS wear ring has tighter tolerances. And it stays tight. By tight I mean I had to file the edge of a blade or two just so it would fit. Search it some. That would be my guess. My wear ring setup is still stock and not messed with and I have no issues with the SS ring. I even tried a RAD4 thinking it was the carbon ring. Still had the stock wear ring at that time. The RAD 4 made no difference. Ended up being my wear ring. like 45 hours on the ski.

    I had the same problem...., it was like if i were burning tires before i went out, but if push it gradually it would not cavitate, 15/20 Solas impeller solved it.... (and if you add an external Intercooler you will feel a hole different power).
    2010 X charger came with new washers..... dont need too...

    I posted about this same problem. I fought mine for about 3 months. Just replace the carbon seal and boot and now she is great. Hard to believe, but that was the problem.
