    Why does my Yamaha Outboard Motor fuel management gauge show incorrect fuel consumption?
    • S
      Sean PetersenSep 9, 2025
      If the fuel management gauge shows incorrect fuel consumption, the engine recognition may be wrong. To resolve this, default the engine number. Then, turn the key switch on in order from the portside engine to re-memorize each engine number.

    Why is the illumination not lighting on my Yamaha FL115AET gauge?
    • M
      Michael RobinsonSep 8, 2025
      If the illumination isn't lighting, it could be because of a power issue or a damaged gauge. You should try replacing the fuse, ensuring the couplers are securely connected, replacing any damaged wires or hubs, or replacing the gauge.

      If the fuel management gauge shows incorrect fuel consumption, the engine recognition might be wrong (especially for multi-applications). To fix this, default the engine number and turn the key switch on in order from the portside engine to re-memorize each engine number.

    Why Yamaha Outboard Motor boat speed and/or coolant pressure gauge does not show?
    • J
      James JacobsSep 5, 2025
      If the boat speed and/or coolant pressure gauge does not show, it is likely that the optional sensor has not been installed. Install the optional sensor.

    What to do if Yamaha FL115AET trim gauge always shows fully tilted up position?
    • E
      Ethan YoungSep 4, 2025
      If the trim gauge always shows a fully tilted-up position, the trim sender signal is not being received. Connect the pink lead connectors to each other.

    What causes Yamaha FL115AET Outboard Motor gauge response to be poor or down?
    • A
      Adam SullivanSep 2, 2025
      If the gauge response is poor or down, a market obtainable unit connected to the system may have failed, or the signal volume has exceeded 50% of the capacity. Try replacing the unit or removing the heavy signal output unit.

    Why Yamaha FL115AET Outboard Motor gauge operates unstably?
    • B
      bmasonSep 1, 2025
      If the gauge operates unstably, it could be because a resistor is not connected to the ending hubs. Connect the gray 6-pin cap to the ending multi-hubs.

    How to fix Yamaha FL115AET trim gauge showing incorrect position?
    • B
      Bryan DouglasAug 31, 2025
      If the trim gauge shows an incorrect position, the initial position setting might be wrong, or the trim sender could be damaged. Put the motor in the fully trimmed-in position and reset the initial (zero) trim angle. If that doesn't work, replace the trim sender.

    Why Yamaha FL115AET Speedometer or Comb. Speedometer & Fuel mgt gauge shows incorrect fuel level?
    • R
      rodriguezmaryAug 30, 2025
      If the speedometer or combination speedometer & fuel management gauge shows an incorrect fuel level, the fuel sensor selection is likely wrong. Set up the fuel sensor to the correct resistance.
