    best impeller for spark

    So I'm looking for the best impeller for my spark. It's the 2up 90hp model and I'm about 190lbs. Looking for best acceleration and pump hookup in rough water. I usually run skat stuff on my other skis, but no experience with sparks yet. I have a Riva impeller housing already also.

    Thanks in advance.

    The solas is very good for the stock 90 spark should have you running 100-200 rpms south of the 8k reve limiter. Does your riva pump housing bolt up to the spark??

    I think he meant a Riva SS wear ring ...

    Brain fart, yes ment wear ring Haha.

    So the Solas is that much better than the skat?

    Oh and would an intake gate or impeller add more to the ski?

    Thanks again!

    If you get a skat for stage 1 tuned, I recommend a 12/13 or 12/12, With stainless wear ring.

    No tuning, not for a few more years tell my warranty is up unfortunately... only way I could get my wife to let me buy one lol.

    Is your vote skat or Solas gasresearch?

    Off the shelf stockers, solas.
    For tuning, skat.

    skat has a completely new 12/14 with an improved blade angle or blade sweep. This new impeller doesn't have any of the cavitation issues the old 12/14 did. this new 12/14 out performs my solas and my old skat.

    Sweet. Do you happen to know if it is designed for stock or with a tune?
