    Brand new RXP, need advice

    Hello everyone, I just bought my brand new RXP and I would like some advice on the 10-hr "Break-in" period. So far, I have 4 hours done. The first two hours was the engine just running, no extra speed or anything. The 3rd hour was me on the jetski going at 2000~2800 rpm . The 4th hour was me driving at 3000~3200 rpm. Now, I have some questions:
    1. Am I on the right track? or should I be driving slower/faster.
    2. What are the max RPMs I can go on for the 5th~10th hours(please list)
    3. I am doing all this on the Nile, so its fresh water, do I still need to flush?

    Thanks in advance!

    Try doing a search for break in procedures. From the sounds of things you need to vary your RPM's much more, as well as do SHORT bursts of wide open throttle. From the hours you have already logged you will be able to go to longer bursts of WOT quicker. DO NOT USE THE LEARNING KEY FOR BREAK IN!!!
    Varying the RPM's and short WOT runs will seat the rings in and give you a better performing machine.

    Are you sure about the full-throttle bursts? It seems very risky. All I am going to do is keep pushing 500~1000rpm every hour I finnish, is this right?

    I wish someone else would respond, but yes I am sure about the WOT bursts. You need to vary your RPM's, the manual even states not to run at the same RPM for a long period. You are half way through the "break-in" so don't worry about a few bursts at wide open throttle. First few should be 10 seconds or so, then go back to riding and varying RPM's then another burst here and there, increasing the bursts by a second or two.

    It never hurts to flush the ski...remember to turn the water on AFTER the ski is started, then turn the water off BEFORE shutting the ski down.

    Yes!!!! Vary your rpm's. Ride it like you stole it just don't keep it wfo for any longer than a few seconds at a time for the first 10 hours. If you ride in fresh water exclusively,there is absolutely no reason to "flush" the engine whatsoever.65 hours and going strong here.

    Well since I have NOT been varying speeds at all. I will start varying speeds from tomorrow morning, I will still keep it in the 0~4500 rpm, but I will push and let go the throttle like crazy so the engine gets "warmed up". Starting from the 6 ~7th hours, I will then begin the full throttle bursts...

    BY THE WAY: After running the engine for about an hour, and when I lifted to see the actual engine(with it switched off ofcource), it was VERY hot, heat all around. And I realized the glove compartment and the big storage at the front also get really hot, is this normal?

    You only have a small opportunity to get those rings seated properly. Give that thing some short 3/4 throttle bursts for 10-15 seconds each every now and then. Once you get 5 hours on it give it some wide open throttle bursts for 10-15 seconds each.

    What you are doing is hurting your ski more than anything. If you break it in right it will run faster. Those who break it in easy like you are doing tend to have the slower skis.

    You are not going to hurt your ski. Drive it like you stole it!!!

    OH, the reason why it was so hot is because you are going TOOOO SLOW!!! Get up and get moving and get some air moving thru that engine compartment.

    Did you read your manual on the breakin proceedure?

    Vary throttle thru all the RPM ranges. This means the upper RPM ranges too!!!

    Man i know it new but trust us on this . You can run it a little harder than that 2500 barely on a good plane and you probably lugging the motor. The first 2 hour run it thru rpm stages and dont hold it at one rpm. After 2 hour hit some wide open burst . i started riding mine hard at 8 hours and the rpm will increase as you break in. Watch your top rpm before the 10 hour service trust me write it down before you take it in . We will then help you after service because 9 time out of ten it will have lower rpms. We can get you thru this part also
