    go for it

    pump wil be great

    you will need an impeller pitvhed at 13/19, Skat impellers have a great holeshot but they are slow on top

    I'd suggest you try the skat pump with a Dynafly impeller that has been repitched to 13/19

    skat trak

    the prop pitch that is on it. I do not know what it is.it has a 15/23 which i can not use with my set up unless i do some major mods.it also has a 14/20 with it. I might be able to use that in the future.the prop that is on it might be a 12/18 or a 13/19.i currently have a 13/20 setback concord on my ski.the skat trak is also setback with the long shaft. Also the teeth look worn.

    if in good condition I have always felt that is the best pump to have for a GPR, better than the HO pump

    but be aware if the teeth on the shaft are worn and the shaft needs replacing they are expensive from skat, something like $350 I think

    i run a blue printed 03 pump, with a 13/19 skat trak 155 type R swirl impellor..

    holeshot is amazing

    , top speed is pretty good, well it is better than a stock prop

    spline

    this is a setback pump. A replacement driveshaft is over 500.00
