    Exhaust backfire

    I was wondering if the pro runabouts run water boxes. When i was at the World Finals I loved hearing the 4 stroke motors back fire around the bouys.

    I have an RXP-X and would love to have mine sound like that.

    You were probably hearing the 4strk turbo skis bouncing off the limiters. I have heard my own skis do it, but not to the same extent as what we heard at the WF.

    If you remove the waterbox, it will do it...and will be obnoxiously ear-piercing loud. I've heard it up close and personal like.
