    best aftermarket impellor for 2000 SUV

    im looking for the best and biggest prop i can get for the SC YAMA-DOO SUV.
    IT A 2000 YAMAHA SUV HULL WITH A STOCK PUMP.
    Ive got approx 240+ hp of SCIC 4tec power and torque so it shouldn't take much to spin something steep.

    we want the steepest pitch i can stuff in that pump.
    whats everyones recomendation for my setup.

    2 options--- a 14/20 concord ( most likely going to have to be repitched higher )
    or since you went through all that work of putting that motor in there, go for the HO PUMP CONVERSION and run the Dynafly ( definately recommend going with the HO pump ) ( probably going to have to go up in pitch also )

    Rapid you would probaby have more responses in the Yamaha performance section, some of the guys have that conversion, here is mostly old school, non power valve.

    Rapid with the weight vs HP your biggest issue will be getting it to move with out cavitating the prop. I have been thinking about this for awhile and I think you might be better off with a Skat 12 or 14 vein pump in it to help with the hook up. Since you are the pioneer in this area I imagine you will have to go through several prop adjustments to find what works best. I would start with the stock pump and a 13/19 see what it does get a baseline and feel for it. then go from there.
