    not yet. Feed all the info you have done about the ski, changes, mods, set up and let the tuners and gurus help you bro before you bail. It could be something as small as a setup change...let the forum peeps help you first

    Hey Jeff, ever live in Oklahoma?


    Anyways, list off your mods and settings and we will help you out. It is all about the tuning.

    2001 GPR 52 hours total, (9 on engine and drive train)
    Kerry hibdon 1456 BB,
    crank works t&w crank
    48mm carbs (buchshots all billet aluminum)
    v-force 2`s
    2006 Pump,transom plate,pump shoe All new
    solas dynafly 14-25 (7300 rpm)
    Jims ff plate
    R&D 1200 grate
    beach house stepped sponsons.(kerrys spec)
    carbon fiber pump reinforcement
    im sure its somthing in the handling set up but i just cant find it,i have shimmed,unshimmed, sanded every which way you can do it and the results are always the same 75.4,75.8 everytime,i did get a 77.3 one time today but couldnt duplicate it.this engine is making huge horse power and torque so i know its not the motor,and i know my prop is a li`l under pitched but i think i should be 5 to 7 mph faster than i am.the other problem is im working 5 and 6 days a week 12 hours a day and i dont have time to mess with it that much and when im not working on saturdays im at the bracket races,leaving out in the morning for races and want get to fool with the ski for 2 weeks.

    Well depending on the person that bent the prop you should be close or over 80 with those RPMs.

    Can you take some pics of the shoe and rideplate?? What kinda tabs and are they shimmed?

    Hello Jeff, If you have used every avenue and you are tired trying to figure it out. Then maybe if you like bring the ski down to Florida and i will take care of it, I'll find the problem.
