    Why does my Yamaha 50HET Outboard Motor fuel management gauge show incorrect fuel consumption?
    • H
      Hannah MccoySep 10, 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.

    What to do if Yamaha Outboard Motor trim gauge always shows fully tilted up position?
    • Z
      Zachary OconnorSep 3, 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 50HET gauge response to be poor or down?
    • J
      James PerezSep 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 Outboard Motor gauge operates unstably?
    • T
      Thomas MorganSep 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 50HET trim gauge showing incorrect position?
    • P
      Philip BradyAug 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 50HET Outboard Motor Speedometer or Comb. Speedometer & Fuel mgt gauge shows incorrect fuel level?
    • S
      Stephen PachecoAug 29, 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.
