    what's the trick? hehe. I have the Riva waterbox and it's a bit too loud. I would like to just have the stock one with a little more sound.

    I ran mine yesterday out of the water and mine does the same thing. probably just that safety steering system that kawi has I guess.

    remember their is no load on the output shaft to help bring the rpms back down, unlike when the prop is in the water creating the resistanace.

    my yamaha get to the rev limiter for 1-2 sec out of the water and when i let go throttle it idlesd like a baby . i think it does it becouse the steering is to the right in that vid. if you rev it with it in the center it doesnt do it so it is the kss system .
