    Question Horse power

    Hey guys, i was talking to a friend of mine about my recent modifications and he asked me: How much horsepower do you now have? i could not answer because i have no way of measuring or estimating.. do we know the accurate stock motor HP output, did yama ever release it?
    with my mods, how would you estimate my HP?

    Not arguing the hp numbers but how is the FZR/FZS just as fast at the Sea-Doo's with much less hp?

    Same as the Kawi has 300 hp and still runs close to the same speed stock....hull design,wetted surface,weight.....etc

    I'll take a guess and say 250 hp depending on how high you are spinning the motor

    Agree with Aquaholic, the Kawi 300 weighs something like 400-450kg compared to FZR's 350kg
