    ok mate tks for the reply
    my ski has gone as fast as 76mph (obviously i have a few tweaks done)

    what other pitched impellers have you tried and able to compare to?

    im still on the 14/21 solas but considering im going to be making mroe power i thought i may benefit from it

    how much did you make above scom only?

    120 is still decent
    out of the hold pull should have been stronger for you also im assuming?

    the fellas who went for the skat 16/21 lost considerable top end but gained alot of holeshot. but they didnt really have their skis set up so interested to see comparitively

    thanks mate

    I had 14/21 in got 119.3 km's at 7850 rpm's. with stock prop and scom I think it was doing around the 115 mark at same revs. I have given up trying to catch my mates seadoo. I have been told these ski's are not designed to go fast on flat water. his S,DOO is doing 128 km's on flat water, can't wait to get out in the bay with him where the conditions will suit the 300 better. good luck with your ski. cheers red

    15/21 is way to steep your wont spin it properly. Buy a 14/21 and pitch from there if needed. I'm betting you need over 375 hp to spin the 15/21 properly.

    Yep. I know a guy here that tried it to and it was too big. He has even tweaked the 14/21 a bit to get the revs back up a touch.

    I'd wait and see what 3 PSI does to your revs and then decide. I'm guessing only 200 rpm. What is Lauri say it will do?

    Cheers, Mal.
