Thread: 6500 rpm?

  1. #1

    6500 rpm?

    I bought a 2005 rxp with 20 hrs. I had a seadoo dealer give it a look over and hook it up to the "BUDS" it all said nothing and everything was good, I took it out it was a windy day, pretty choppy. Could only get it to top out at 6500 rpm with trim one above middle. I've heard I should get somewhere near 8000rpm's?

    I think 6500 rpm is the "Uh-Oh" number. Ceramic washers bit it!
    Pull the sc & check them out.

    Oh yeah It had a full tank of gas from last year before it was stored?
    How high of an octane can safetly run I'm shooting for 110. That is after the rpm issue of course.

    make sure your not running bad/old gas too. 6400 is not a good number, but it seems to be indicative of SC'er washers gone OR fuel/spark plug issues. lots of guys are seeing big performance loss from fouling plugs on bad gas. though, the caveat: you don't want to run the engine incase the washers are toast, so pulling the SC'er and having a look is a good idea too! did you hear the SC'er while it was running?

    Pull the hose off that goes from the S/C to the throttle body. stick your finger in the S/C and see if you can spin the wheel easily. IF you can, your S/C ate the clutches...

    all you need is 93octane. running 110 on a stock motor is not necessary.

    Well I've worked on cars alot, actually just got out of racing asphalt modifieds so I think I'd be able to handle it, but I don't see a whole lot of room to do anything? Realisticly how hard is it and is it worth paying someone else to do it(seadoo dealer)?

    since you have wrenching experience, you'd definately kick yourself in the nutz to pay a dealer WAY too much to do a job you can do in less than 30 minutes. visit the "How To" section. there is a SC'er removal write-up and just about anything else you'll want to know. You'll just need basic hand tools to remove the SC'er, but you'll need a couple specialty tools to change out the washers.

    a couple hose clamps and 3 bolts and your SC'er is in you hands.
