    modding the HO

    Anyone looked at the reduction gear.. changing it out to yield 8000 rpm max ?

    Any intake /ride plate / hull mods done by anyone?


    don't expect anyone has but wondering...since this might be a good endurance boat i thought maybe someone has..

    Have you considered calling Rius shop and attempting to talk to them? That was a fast ski at last years Hahn300.

    riva rpm kit or [email protected] and there around 62-64mph add [email protected] nozzle and another .5-1mph

    it would be nice if there was a cam and piston kit for them get some more revs out of pump

    25 super charger kits were made and most ran 70mph+

    the kit is no longer available from riva

    think Yamaha have a model soon ready for release with a super charger in a extended gpr or vx hull
