    Only 52 MPH on RXT X

    I am only getting to 52 mph on my RXT X. When I called the person I purchased it from, they told me to check the green billet impeller cone on the after market impeller. It was loose. I have not put the boat back in the water yet, but i am curious to if this could cause a 20 mph difference???!!!!

    Doubt it...First check all your hoses and make sure they are snug and that you don't have a boost leak..if all looks ok, then pull off your intake hose to the SC and see if the SC blade spins freely..The RXT-X's have metal clutch washers but they are still prone to breaking up.. If neither one is off or missing check your fuel and plugs..

    If it's not any of the above, find someone on the forum that is close to you and let them have a closer look.. I don't know where your from because I didn't look but if it's close to Ft. Lauderdale, bring her by.

    Was the green nose cone loose or completely unscrewed and moved up shaft?

    Check:
    1) intercooler hoses - besure hoses are still connected with clamps still tight
    2) exhaust hose (4.5 inch black hose that connects to exhaust pipe)
    3) check super charger slip (I had to shim my X sc on T-X at 40 hours)
    4) be sure are using yellow key and not white
    5) oil - check oil level to be in between markings when warm
    6) be sure there is nothing sucked up into pump and that your nose cone has not moved up shaft.

    Someone else chime in if I missed something

    The cone was loose. I will check everything else when I get back to my house.

    What you said about what you had to do at 40 hrs, is that covered under warranty?

    I don't think this is your problem but make sure you're using the yellow dess key and not the white one.
