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 r@d and there around 62-64mph add r@d 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
