    Question What Impeller should I run?

    I need some help with what impeller I should be running with the following combo.

    Ski is an 07 RXT with the following mods;
    - Riva free flow exhaust
    - 4" air intake
    - Green wheel
    - XS Cooler
    - 42 injectors
    - Worx grate

    What impeller should I start with and tweak it if need be to stay around the 8100rpm mark?

    Also what is the difference between a Solas 14/19 and 14/19R??

    Cheers

    i'm running a GTX (same ski) with same mods except i have riva 3" intake. I use a 13/19 and it keeps me right at 8100-8150 (57L, 51 air). I beleive R means that it has been pitch blocked by the manufacturer for pitch accuracy. With the 4" intake you may be pushing a bit more RPMs, but i would suggest starting at 13/19, although some would say go 15/20.

    I'm sure someone else will chime in

    I have the exact same setup in an RXP I had to go to a 15/20R with the 2 seater you may need less prop with your 3 I dunno. I have a 14/19R that is untouched and I will sell off cheap since I cannot use it with my Stage II craft.

    R means the Prop was pitch blocked to ensure accuracy when leaving manufacturing.

    Does it make any difference if I run a 14/19R 4 blade (assuming all Solas are 4 blade) or a 14/19 3 blade?

    I understand that the 3 blade is supposed to have a lot better bottom end (hotshot?) while the 4 blade will give better top end. Riding 100% in the ocean would a 3 blade be a better option?

    Cheers.

    That is the word, 3 blade=better hole shot for the ocean.....

    if you really tweak it right you shouldn't lose more than 1 MPH boat for boat,,,,Hole shot and head start will win unless your doing the 1.5 Mile drag race...

    OR

    going for top end...
