    So what mods do you have that would be considered the Riva Stage III?

    I would start with a YS-DF-15/22 and bend it from there to get RPM's you want. You also need a tach. You also didn't mention anything about a ride plate. Are you running the stock SHO plate?

    Ride plate is stock, I do not have budget for it yet, in my country is almost impossible to mod a prop.
    Thx

    You could pitch the prop yourself, if you're up for it. You'll need a prop gauge and take a look at this thread: http://www.greenhulk.net/forums/showthread.php?t=20995

    You do not want a 155mm impeller with a Stage 3. With the mods on your ski you will want this 160mm impeller in 13/19 pitch

    160mm wear ring

    and don't forget the Lucky 13 adjustable pump cone
