    Angry My $3,500 screw.....

    At the end of last month my '06 RXP with 140 hours experienced an engine failure on Lake Mead which required a 20 mile tow back to the launch.

    When I inspected the ski I noticed that the front oil pump housing was cracked and that's what allowed the oil to spill into the hull shutting the ski down. I pulled the supercharger and spark plugs - they were all perfect.

    At that point I decided the repair was going to be more than I was willing to tackle and I sold the ski for $3,000. (About $3,500 less than it would have sold for before the failure. )

    I just received an e-mail from the guy I sold the ski to and he included a picture of the "root cause" of the problem.

    Any guesses where the screw came from?

    I sent him an e-mail asking for more information, but right now the only clue I have is the picture he sent.

    hard to tell from the pic but is the head rounded and is it a 5mm allen head bolt? If so it looks like a cam sprocket bolt but looks too long for that.....

    What about the 2 bolts that go facing down beneath the chain below the cam sprocket. I dont remember what there called.

    No, that's the part that's killing me. The ski was perfect, never had a problem and had an easy life.

    I should note that the ski had a vibration about two minutes before it shut down. I'm pretty sure I had something caught in the pump and the vibrations caused the screw to come loose.

    Ironically, the vibration went away about 30 seconds before the front oil pump housing cracked.

    It almost looks like a self tapping screw of some sort by what the bottom of the screw looks like.

    Any chance of someone tossing a screw in the oil fill, just to ruin someone elses day?

    It looks like one of the ones that hold the sc on but I cant imagine how it would have wound up in the engine unless it was dropped.
