    Will 05-08 GPR1300 Impeller work/fit in 03-04?

    I have a DF 13/19 Impeller from my 07 GPR1300.
    Can this be used to replace stock impeller in a 03 GPR1300 since there are pump differences?
    If it can, will there be any performance gains by doing this?

    Thanks in advance, Ceril

    No. Different size hub

    ?? eh.!

    the prop will fit just fine and will work considerably better than the piece of shit 4 blade impeller that came on the 03-04's

    Yes. the non HO pump stator hub in the 03-04 years is smaller as ctct2118 said.
    it makes little or no difference if the earlier stator is used.

    I've run the stock 05-08 props In 03-04's makes a nice improvement. (the OEM 05-08 props are pretty good stock and repitch well)

    give the dynafly a whirl in your ski. if it's a true 13/19 you'll be happy..

    Thanks guys.
    A little confusing with the two responses. One definite NO, and one YES, I think.

    So sounds like it can be done and there is no downside but only potential upside.
    Now that you mention it I also still have the stock 07 impeller also.
    The DF 13/19 I got as a DF 14/20 pitched to 13/19 by Carl at Island Racing some years ago.
    I have a riding buddy with a stock 03 GP1300R and wanted to offer one of these impellers to him to try out.
    Which one is better choice?

    The Dynafly will work in a non-HO pump well, but with no mods it may be a little hard to turn a 14/20 to correct rpms. The 13/19 may be the ticket

    Sorry for the bad info. I learned something today.

    Another good one is to try the 03/04 stock 4 blade impeller in a mildly modded 1200. Works real well also
