    RXP-X cavitation

    I have an RXP-X that just turned 24 hours old. I was riding this morning and was doing some hole shots and there was suddenly noticible cavitation on the launch to the point were it would run up to 8160 then catch and start to take off. I thought I had picked up some debris in the pump but it would only happen on takeoff and smooth out completely once you were cruising. This had never happened before. It didn't know what was happening so I took it out of the water and took it home. At home I looked at what I could see and noticed that a rubber boot thing on the drive shaft on the intake grate side of the impeller was all distorted and looked like it had gone goofy and distorted. Is this likely the cause of the cavitation and is this a "problem" that other people have had. Is this something that should be covered by warranty?
    Any feedback would be greatly appreciated.

    what do you mean by goofy and distorted. I think we might need some pics.

    That's the cone for the junction between the drive shaft & the impeller. Yes, it can cause cavitation at take-off. When I put the Solas on mine I noticed the leading lip on the stock cone was folded under. It only had about 5 hours at the time, but I'm sure very soon it would have ended up like yours.

    Should be a warranty item.

    Cavitation on holeshot

    I managed to get a picture through the intake grate. It looks like the rubber boot on the shaft has split or something. Would this do it? Anybody got any ideas?

    Some members on the board run without the impeller boot. If it's cracked, I would take a razor knife and cut it off... Ron

    RXP-X Cavitation

    Okay next question. What is the purpose of the boot it must be there for a reason. Should I get it replaced at the dealership under warranty or surgically remove it as suggested.

    The cone is used to help seal water from getting into the prop and driveshaft splines..If you ride in fresh water conditions it will not hurt to remove it entirely from your machine..IF you run in salt water conditions though i would replace it either with a new OEM one or see if a board member has a metal one laying aound they dont want or need..


    And yes that will cause your cavitation...

    Cavitation

    Thanks. Appreciate the feedback.
    Is the metal boot a seadoo part or aftermarket.
    Do you have a part number for it or manufacturer info?
