    Stock Class boats

    If you had to build a boat legal for the stock class. A closed course or enduro boat what parts would you put on it. Impeller pitch ,air filter etc

    For a rxp I'd use Stock Class ECU, Riva air filter, Riva sponsons, Riva intake grate, Solas prop a 14/19 i think, mod the ride plate, Riva or Rotax thermo stat, Riva opas block offs, and I think thats about it. Friend of mine has a stock class RXP that runs 73-74mph in perfect conditions.

    Has anyone tried the stock class ecu in a stock boat. If so did you notice a difference.

    I heard those stock class ECU's make alot of difference. Not to mention you benefit from the higher rev limit.

    The full blown Rotax Racing ECU has a more aggressive timing/fuel map creating more horsepower. I have never tested them back to back to get any real world numbers on them.
