    Ported and / or Big Bore ski's

    Just curious who all on this forum in running ported and/or big bore skis? How about a list, CC's, who did the port / bore work, best top speed, any regrets. If you don't wish to post your info I can respect that. Just curious how all the different ported skis fair amongst each other! I'll start..

    1300 cc's
    Ported by Kerry Hibdon
    Best top speed 77.7 mph
    Any regrets- None, due to how much I learned about my ski.

    Got some driveshaft issues, and some crankshaft height questions.

    After that.... it's no big deal.

    that is interesting,,no offense but if i were going to go to the trouble of putting a sc engine in a gpr hull it would most definately of been the kawasaki 15f sc engine ,,but then again i dont know the details that engine might not fit in the gpr hull.

    No offense taken Jeff. It's all about seeing if it can be done. I have no regrets. If it fails, then I won't worry too much about it. It's just something I've wanted to do since 2004.

    The kawi engine would surely have been easier, but I like the higher torque numbers coming off the Rotax plant. It might just push a big prop at 8000rpms plus.

    well if it dont work and you want to get rid of that engine,,i know a guy looking for a good used one,,his suffered water ingestion (total loss)and warranty already ran out,,,dealer told him $5500 or find a used one that was 6 months ago hes had no luck finding a used one.hope it works though i would love to see what that gpr hull would do with that much hp,,by the way what is the weight difference between the gpr and rxp engines? and also if it works you better wear all of your protective gear when testing.
