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.

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
gps 52.3mph before
gps 53.1 after
but it was 12degrees cooler on the second test day, my speedometer reeds 57mph and 58 after

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
