    Pump Relief

    Hey guys been searching for a few days on the pump extension and pressure relief setup for my GPR. I have everything I need but I am wondering about the 2" extension and modifying the impellar shaft. How has everyone been extending the shaft to support the 2" extension? Or does this even need to be done, maybe I am missing something.


    Thanks in advance for the advise!!

    What year ski do you have? If its a 2000, 2001, 2003-2004 you need to change the Intermediary shaft and you use your stock driveshaft... if its a 2002 you use your stock intermediary shaft but use a 2001 driveshaft.

    if you are slower than that no relief is needed
