    Thumbs up What Impeller To Use?

    I have done a few mods to my '95 SL750 and am looking to add an impeller to gain some top end speed. I have no idea what prop to go with or how to determine which prop would get me the most speed. The following are the basic mods I have done:

    Already done:
    Ocean Pro Ride Plate
    R&D Intake Grate
    Hot Seat Water Box

    I have the follwoing to add this summer:
    V-Force Reeds
    6° wedge (will this really do anything since this ski has trim?)

    Looking for:
    Flame Arrestors

    Are ther other bolt ons that I can get to add to this without having to do any major motor work?

    Thanks

    Thanks Beerdart,

    I have seen this chart before, the problem is that I don't really know what the numbers mean and how they translate into speed or torque. I guess this is really what I am asking for help on.

    I would recommend a NuJet 5.0

    The biggest mod gain for the money is higher compression heads...around 150-155psi. If you get the heads, then I would recommend a NuJet 5.5

    If speed is what you're looking for, don't get the Skat Trak swirl impeller. They give good bottom end, but robs from the top end. Now remember, if top speed is all you want, you will lose out of the hole acceleration.

    You should go with the 13/18 skat-trak swirl. There is a list your mods post where you can see what others have done to their skis. It will give you an idea on what you may want to do. There is a lot that can be done to the 750. If you look at my ski above it has the 14/19 because the nozzle is bored. I just thought I should point that out so you don't get confused.

    Yes 6 is good for top speed, 4 might be better for rough water. I like the 6.

    Are ther other bolt ons that I can get to add to this without having to do any major motor work?

    Depends on what you consider major work, see link to my 750. Swaping the fitting on the top of your exhaust to that of a 780 is simple and about 100 rpms.
