    Bone stock RXT-X speeds

    I got out on a nice flat surface and it topped at
    67-68(stock speedo) at 7820 RPM
    Does this sound right for a factory ski with 4 hours on it?
    Thanks

    with 7,800 rpms i would say your speed is right. get some more hours on it and see what rpms are at 10 hours. If below 8,000 then a slight pitch in prop will fine tune it.

    67 to 68mph and 8000 rpm is what all T-X boat run, stock. They have tested about 10 of them around here, and all run the same. If somebody is getting 70mph then they got an extremely good running ski, or they weigh 130lbs...and/or the temp is 60deg and they are at sea level running in salt water on a river with a 3mph current.

    Your RPM should pick up after about 8hours. But I never noticed it on my T-X. It would run 7980 to 8000 from zero hours, all the way to past 10 hours. Supposedly the ECU limits top RPMs until 8 hours.
