    2004 RXP Performance is this normal?

    Hey guys I need some opinions on this:

    Today I tested a 2004 RXP for sale that my Dad is interested in buying. This ski is totally stock including the supercharger with only 26 hrs. The ski seemed pretty lame compared to my friends 05 stock RXP and other friends stock 08 rxpx. It only turned 7250-7300 on the tach and GPsd at 61.7 on the buzzer. I checked the oil and being unfamiliar with seadoos I'm not certain but it seemed way overfilled.

    I called my friend who was also on the water to see what rpms he was turning. He reported 7600 and later I loaned him my gps and his only ran 62.2.

    What RPMs should a good condition 04-06 RXP run and at what speed should it run?

    If these are abnormally slow speeds (both of my skis ran good on gps today) what could be the cause? Could the superchargers be slipping since they haven't had them upgraded? Or could simply overfilling the oil account for that poor performance? To add I think my friends ski has about 80 hrs on it and thought it was more like a 65 mph boat.

    Thanks

    Pull the S/C and check the washers! Are they still there! The 04 RXP has an aggressive stock cam and that boat should be between 67-68 GPS in stock form! The oil should be half way between the bends when the motor is warm!

    Another note... RPM's should be around 7800-7900 minimum on a stock machine.

    To much oil will lower your rpm's,but i doubt that's the only problem.

    Rpm's should be around 8000 minimum,8100 is better,depending on a hot or cold climate.

    I would check the supercharger,to be safe!

    Normally the 215 hp gives a massive holeshot,and speed around 67 mph as mentioned earlier.

    I'd bet money that both the ski you're looking at and your friend's ski need the knock sensor update, see below. The ski you're looking at is prob. a combo of needing the knock sensor update and overfilled oil.

    I doubt it's supercharger failure, rpms and speed are too high.

    I agree! You will need to install the knock sensor piggy back harness. See the link posted above.

    Let us know how it goes!

    Knock sensor

    Thanks for all the input I'll definitely look into the knock sensor. I forgot to add that the ski I tested for my Dad was only running regular gas.

    Thanks for looking this up HighVelocity, I am placing an order with GreenHulk this afternoon.

    $35 for the Harness and $65 for the handlebar pad that the cat shredded, oh well
