    engines are running different RPM's at the same throttle positions

    Is it normal to have to play with the two throttle levers to get the RPMS to match or should they be the same as you push both of them up together? My RPMS will be off a good 500RPMS while cruising, enough to steer the boat. I have to push the other throttle lever up an inch or so to level out the RPMS. It's an '05 370hp Speedster 200. Only mods are 4" intake and resonators removed.

    I have an 04 speedster200 with 310hp and both engines are perfectly in tune, RPM's on both engines are identical throughout the throttle range. Sounds like one of your engines needs to be setup or tuned up.

    don't think you have the same problem since you only have one engine compared to two!! lol

    Just adjust the throttle cable linkage at the throttle body to even it out.
