    yes the GPR nozzle will just bolt up

    you will need to drill and tap 4 holes that are used to mount the reverse bucket

    My ski has adjustable trim control on the handle bars that moves the nozzle up and down so would it make sense to change it to a gpr nozzle that is stationery and if I did would I get more speed ? Thanks

    the gpr has the same ajustable trim
    i think the fx skis have a 5deg exit nozzle as well and will have the holes for the reverse bucket already drilled

    They are talking about the pump reduction nozzle, this is what your trim system bolts to. XLT's come out of the pump at a 3* angle GPR's come out of the pump at a 5* angle. The adjustable trim system bolts on this and both skis have them. The XLT has reverse and the mechanism bolts on to the reduction nozzle. The gpr reduction nozzle is not drilled and tapped for this, so it is necessary to do this if you upgrade.

    gpr nozzle

    once I change the nozzle in what area will I see a change low end or top end ?

    Does the nozzle have to be from a gpr 12 or 1300 or does it even matter and what kind of change can I expect from this modification.

    Greater angle on the nozzle (GPR) allows for less of the ski to be in the water on plane, meaning less drag. Less angle on the nozzle (XLT) keeps the ski more planted in rough water, but it also means less speed in flat, smooth water because there's more drag. It works on the same principle as angling the rideplate.

    so does this mean my ski can benefit from a pump reduction nozzle off of a gpr even if I have trim control? Thanks
