    13-19 DF

    Does anyone have first hand experience of a repitched dynafly on a stock 08 gpr?
    What should I expect?

    run a 14/19 on my jump boat from time to time,same engine as your 08 with a few tweeks

    you wont look back once you have one in conjuction with your free flow,

    people say the stock prop is good for 70mph and i would tent to agree in most cases but as a all round package the 13/19 better as it gives a real hard puch in the mid range where i think the stock prop lacks a little

    Hopefully Riva will include these new props in their Stage 1 kits now so people can actually turn the correct rpm's

    Will it hit as hard as the stock prop off the mark and low down?

    Most people will say no but you will have a better mid-range and top-end.

    i found the stock 12/17 got hit too hard out the hole with a few mods and with a free flow the 12 was too low for my skis and just spun up tooo fast and the water could not be processed or enter quick enough


    i found my 15/19 is mega out the hole but gives a few rpms away on top due to the 15 loading up the pump to much

    ohh this is true also...I was thinking about a thread a while back but that was saying switchin to a 13/19 with basically a stock motor. Hydro's right

    Well I have a freeflow so I am looking for a bit of punch and also a wee bit on top.

    Forget deptiching. Save your pennies and do 150lb compression and a EFI controller.
