    08 Fx- sho loss of top speed

    buddy has a 08 fx-sho. It started to lose top speed towards the end of the summer. Tops out now at 62 mph at 9,800 rpm's. I checked the pump as best I could and it seems clear. The ski has about 130hrs on it. I read somewhere that the superchargers need to sometimes be rebuilt. Top speed at beginning of summer was about 70-71 on the stock guage. Thanks for your help!

    I bet the prop is all banged up and/or the wear ring needs to be replaced
