    RXT break in and oil level

    Hi,

    I am in the process of breaking in my new RXT, done about 5 hours now. I noticed that my max RPM with yellow key is about 7620rpm on flat water regardless of fuel level. This is in the ocean, water temp 75F and air temp 85F.

    I checked my oil level on the trailer while engine was still warm and it was on the top kink of the dip stick. At this point the ski was out of the water for about 20min. I will do another hot check on the water next time I am out.

    I am pretty certain that there is too much oil in there and I would like to get it out. My question is why do Seadoo put too much oil in the engine? Is this required for the break in period?

    I thought the idea was to use all RPM during break in and at the moment I can not do that. My understanding is that these should be revving to about 7950rpm?

    Cheers.

    I would lower the oil level to between the kinks on the dipstick. Oil level does affect the RPM's on these 4-tecs. Try that first and go from there.

    the computer does limit the rpm for the forst few hrs to less than max rpm, you might still be in that reduction time period.
    however, you should pull a little oil out for best performance during break in.
    also you should not be doing much max rpm, high speed runs. once or twice an hour for the next few hrs still. no more than a few sec of max rpm at a time.
    lots of variation in rpm all around the powerband, and hard accelrations, just not up to max rpm... yet
    at 10 hrs you need a service by the dealer to maintain your warranty.

    very true, but on my wife's 2006 RXP I was seeing higher RPM's than that at 5 hours.

    Yes I have been doing all the suggested break in stuff and not too many max rpm runs for about 5-10 seconds at the most.

    Most of the time the engine is doing about 3000-6500rpm and I constantly vary the rpm up and down and put load on it etc.

    It is going to get a 10 hour service once I get there

    Cheers for the link RX951, great info in there

    One more question. If my oil is at top kink, how much oil should I be taking out to get it down to about 1/3 - 1/2 between the kinks when warm?

    I am all metric too. Would it be 0.2L, 0.3L, 0.4L.....?

    Cheers

    I would say .25 to .50 Liter taken out would
    get you from top of bend at dispstick to
    the bottom of bend at dipstick...
    You should take out about half liter, then ride til
    warm. Shut off. Let sit 30 seconds.. then check.
    You can always add just a tad bit of new it if you
    take out too much.

    my 08 GTX definetly was overfilled when i 1st got it(not by alot though)....make sure the ski is level when you check it....i put a level on the side bumper before checking it....another thing i did was used some steel wool on the dipstick to lighten it up a bit(easier to read)....my rpms were "governed" at 1st as well, but that stopped right around the 5 hr mark for me.

    be sure to read the instructions for checking oil in the owners manual. if you remove some oil, be sure to take some more to the water with you in case you need to add some back to get the level just right.

    If you had 5 hours on it the last time you rode, the RPM's will go up another 100 or so the next time you ride.
