    07 gtx 155 Info?

    How'd, A mate of mine just purchased a 07 gtx 155, I rode it yesterday and it felt very slow! Can anyone tell me what the max rpm's should be? The most I saw was around 7200-7300. The ski has 39hrs.

    Thanks ED

    mate

    yo man
    youv jumped from a 150hp 2 stroke, a 215hp supercharged 2 and 3 seater 4 stroke, to a 155hp 4stroke,
    i have a 130hp gti and i cant imagine the power differnce.
    yeah mine only gets about 7300 before the limiter lets in. i think thats what restricts the power.ok let me know if you find anything

    06 gti 130

    I haven't juumped anywhere! Read the post- "a mate just purchased". I've only ever owned 2 seaters, and my current ride is a RXP X with some mods.

    I have a 03 GTX with the 155hp NA engine. I had it out at the lake yesterday and the max RPM's I can hit on the Seadoo gauge is 7300-7400. I thought I had seen someone else post in another discussion that this engine should get to 7600, but not sure??? I also would like to get another 200rpm out of my ski.

    I have a 07 GTX155. 7400 sounds about right as far as my max rpm. Mine is totally stock the fastest I have ever got it is 59, my friend (who happens to be about 40 or 50 lbs lighter) got it up to 61.

    Thanks for the help, I think the rpm's are about right, but the speed is way down, the speedo was only showing about 85km/h (just over 50mph) and I checked it with my ski side by side. I think we better have a look at the wear ring?
    Thanks again ED
