    09 fx sho intake grate/impeller

    What would be the best intake grate and impeller to use? The ski is used for Big Wave tow in surfing. Dont need a lot of top speed, looking for bottom end torque and hook up. What are the choices and Why?

    On a stock ski, I doubt a Skat prop will do any better than the stocker. The stock prop is very similar to the Skat...same swirl blade design. For tow surfing, I assume you want the best possible acceleration & low-mid end. The stock prop does this very well. Since cavitation tends to get worse in salt water, especially in foamy surf, you might want to add 1* to the leading edge. The stock pitch is 12/20, so have it repitched to 13/20.

    Also, adding the anti-cavitation cone & pump seal kit will yield better results for your application. I use the Riva grate, but have heard the R&D is a little better in rough water.

    Thanks for the info, will look into that. Do you know where I can get a good used prop, the owner of the boat hit some coral and broke the intake grate, piece of it got stuck in impeller and bent the trailing edges. Would like to start out with a good prop, repitch it a bit and add a intake grate, pump seal, and anti-cavitation cone, to see how this works in BIG waves.
