    What is required to convert XLT over the the newer HO pump?

    Considering converting to the HO pump, what is required. I know the 2" pump extension and the longer shaft, reverse and trim cable extension too. Anything else? Is the stator portion any different?

    Yes, everything fits the same but the center is bigger. I'm pretty sure they both have the same amount of pump veins, not to sure if there is a difference in the shape of the veins. The additional size of the center helps keep the water in the pump longer so it doesn't unload as fast.

    stators are the same... uses different rear cone

    same driveshaft, bearings, seals, nozzle, impeller


    edit: HO pump works best with 85mm nozzle and dynafly

    You do NOT want to run a 2" extension on an XLT hull.

    Yellow, Why wouldn't you want to do that?

    My 1390 XLT that Fercho helped build didn't have one and I was told it was not a good idea. You should ask Jim about because I think he was one of the ones that told me that... can't be sure who told me that though because its been several years now.

    The 2inch spacer works well with the stock xlt shoe for the rough no speed gains.

    Thought the point of the spacer is to prevent over-stuffing?

    So would a pressure-relief in the tunnel help resolve this?
