    Anyone tried new riva 12/14 impeller

    Hello I have a 110hp spark and Solas 12/17 impeller, also have exhaust, intake ribbon delete, stainless wear ring, r&d intake grate and pump seal. I'm not running any faster top end then then a 110hp tuned spark with nothing else done. My revs are also only 7700 which is pushing me toward an impeller swap.
    Thanks!

    I just sent my 12/14 in to IMPROS to bend to 12/15. This seems to be a good bend for non Turbos. Double check the RD intake, mine was not flush with hull and that will scrub speed.

    BTW my 12/14 spun with similar mods.

    As far as I know the 12/14 is nothing but a repitched 12/17 anyway so just go ahead and get yours pitched. I have also heard 12/15 is the way to go.

    I have also noticed this about my intake grate. Should I ditch it for the factory or a riva or maybe try to adjust it? I'm also in Canada and not really sure how to go about a repitch on my 12/17

    I'm currently running a 8350 tune, would this tune still be okay with the impeller repitched to 12/15?

    I have same situation 110hp 8500 tune and only see 7800 on the rpm with solas 12/17 I was thinking try the stock prop and see if it picks up any revs and top end.
    But totally happy with bottom hols shot and mid range

    Xdrian I tried that rpms were hitting 8200 however holes hot wasn't as good. I'd rather lower rpms and better holeshot . Top speed wasn't much different.

    Xdrian,

    When I put my stock prop back on I gained about 200 RPM...

    It looks like the stock prop still better all round
