I bought this 2002 GTX RFI a couple weeks ago, first time in the water today. It has a lot of cavitation and the engine revs really high while accelerating from slow speed. It gets up on step ok but it just seems to me it is a little slow accelerating. Tops out about 48, according to my wife on her wave runner. I suspect it is probably the wear ring, an I on the right track? Also, when first accelerating the speedometer will work to about 30 then drops to 0, any suggestions?
