    Thumbs up GPR-SHO Conversion - Handling

    Hey guys,

    The stars have aligned and the parts have become available for me and my buds to build a GPR-SHO. We're anticipating the type of hp and hull-setup we want to be running and a nagging question that keeps surfacing is "How well will this boat handle with all that extra weight up front from the motor"?

    Has any1 setup their GPRXP for handling/twisties and had any handling issues?
    how do these bad boys carve?

    Appreciate ur input......thx

    Hull responds great with the SD motor in it. Close to the same weight only a little futher forward. Some that I have set up handle much better then ones with equal handling mods. Not sure what the SHO motor weighs.

    According to hydrotoys........about 300 lbs. My thinking was that with the extra weight ballast in the front...the ski would dig more in the turns (added downforce)...and if she started to plow.....fix that with a flick of the throttle to swing the azz of the ski around and launch out of the turns like a rocket.....

    Very happy to hear this....thx Duke

    300 pounds!!!!!! A fully loaded 4-tec only weighs a hair over 200.

    there is no more weight "up front."

    What? Are you planning on cutting the engine in half and putting a couple of cylinders up in front of the gas tank?

    All the weight is in the EXACT same spot as the STOCK GPR13R or the GPRXP, or the SHO-GPR.

    The only difference is that the SHO gpr will be 75ish pounds heavier than the STOCK GPRXP. Now if you take that stock gprxp and add in an aftermarket IC, I'd bet your differences are down to 60lbs. Add in the weight from the J-PIPE and your differences are down to 55lbs.

    It's just going to be a tad slower off the line. This is fixable by a different prop setup.
