    Old school gp1200 conversion

    To build or not to build is the first question.
    Wanting a good winter project and want it to be something different. So here is the idea
    Gp1200 with the RXP 215hp 1500 supercharged motor.
    As far as I have read this has not been done yet. I read the build on here about an attempt that went cold from fraud and it really looked like it is possible.
    Few things I would really like some advise on are
    -Best options and tips as to how to get it to hook up? lotta power in front of the ol pump design
    -stability concerns are a big one. What tips,thoughts,ideas to make this as stable as possible?

    I am a huge fan of big numbers on the GPS but at the same time I am not a complete fool, I do understand that this hull was not ment to go 100mph. I think it would make a great toy, fun project and a monster of a bottom and mid range ski. Plus the fact that to what I can tell it would be the first. Just wanna try something different

    did you click the link? somebody was able to make a GPR pump conversion work in a GP...and apparently there is are people who have made a Seadoo pump conversion work on a GPR...so theoretically there should be a way to make a Seadoo pump work in a GP. I guess what I'm getting at is, if the ol GP pump doesn't cut it for your RXP conversion...there are other options to explore.

    i was the one who put a gpr pump in a raider/gp with a dyna fly prop just have to send it to skat trak to machine to fit our driveshaft. i think i still have pics somewhere-personally i think the stock pump would work fine i used the stock pump in the blue angel raider and it put out well over 200hp

    My 99 is running 70 mph with a ported motor and the stock pump I might have 165-170 hp 215 hp might get you close to 90 mph.Aint no handling problems at 70 mph I dont think there would be at 90 either.If you had 250-300 hp I would think 100 mph would be easy.
    I would call it a GP1500S
    GP1500(swap)
