seadoo GTX260 top speed low rpm 

i made some progress on mine. had the same issue. My ski had a solas prop in it that was the recommended pitch. i switched it to a stock prop and gained about 500 rpm. I then swapped injectors with a good ski I had and gained some more and now I'm running 64 mph at 7780 7800 rpm. I recommend taking your injectors to an automotive performance shop and having them test them then clean them and test them again. should be about 20 bucks a piece. My ski still does not feel completely there but it is better.

Did you fix this issue? I'm having the same.

any luck on this. mine is doing the same
