  • yamaha fuel management system

    I have a Century 300 with twin yamaha 250's and the dual engine fuel managemnet system. The P 9Port) and S (starboard) indicators only appear in the beginging and it is only provining information on one engine. Does anyone know where I should start and what the dip switches control.

    you should be able, while running to toggle between the 2 .
    take out the non reading sensor, blow thru it with gauges on and see if you get a reading as they clog easily.

      The issue is I can't toggle between the two and that's not even an option because the PS indicators are not visible and pressing the set button doesn't do anything.

              The boat is new to me and has not worked right yet.
