just purchased a used 2002 gtx di had it out on the lake, and only getting a top speed of 50 mph. would have expected closer to 60. does anyone know what should be the top speed.
I am not really sure what the factory rated top speed is supposed to be. For the new 255 HP ski's max top speed is 68 MPH which is electronically governed due to this being the Coast Guards max allowable speed for a PWC that is not a race ski.
