    What to do if my Yamaha Outboard Motor gauge display does not wake up?
    • T
      Troy WeaverAug 18, 2025
      If the gauge display doesn't wake up, it could be due to a lack of electrical power or a damaged gauge. Try these steps: replace the fuse, securely connect the couplers, replace any damaged wires or hubs, or replace the gauge itself.

    Why does my Yamaha F115B fuel management gauge show incorrect fuel consumption?
    • T
      Tara WhiteAug 22, 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.

    How to fix a Yamaha F115B tachometer that shows incorrect engine RPM?
    • J
      Jonathan SmithAug 26, 2025
      If the tachometer shows an incorrect engine RPM, the engine recognition might be wrong. Push the SET button for 10 seconds to default the engine number, and then memorize each engine number again.

    What to do if my Yamaha Outboard Motor speedometer shows the incorrect fuel level?
    • P
      Patricia SosaAug 28, 2025
      If the speedometer shows an incorrect fuel level, the fuel sensor selection is likely wrong. You should set up the fuel sensor to the correct resistance.

    What does it mean when my Yamaha F115B gauge shows “----”?
    • M
      Mr. Michael GomezAug 30, 2025
      If the gauge shows “----”, it indicates that the digital signal is not being received. Make sure the couplers are securely connected and replace any damaged bus wires or hubs.

    Why does my Yamaha Outboard Motor fuel management gauge show incorrect remaining fuel?
    • J
      Jeremiah DavisSep 2, 2025
      If the fuel management gauge shows incorrect remaining fuel, the fuel capacity setting is probably wrong. Fill the tank with fuel, and then set the correct fuel tank capacity.

    Why does my Yamaha F115B trim gauge show the incorrect position?
    • N
      Nathaniel NolanSep 4, 2025
      If the trim gauge shows an incorrect position, the initial position setting might be wrong, or the trim sensor 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 sensor.
  • S
    salvarezSep 6, 2025
    Why is my Yamaha F115B Outboard Motor gauge operating unstably?
    • J
      joseph20Sep 6, 2025
      If the gauge operates unstably, it's likely that the resistor isn't connected to the ending hubs. Connect the gray 6-pin cap to the ending multi-hubs to resolve this.
  • K
    Kristie HawkinsSep 9, 2025
    Why is the Yamaha F115B gauge response poor?
    • T
      Thomas LongSep 9, 2025
      If the gauge response is poor, a market obtainable unit connected to the system may have failed, or the signal volume has exceeded 50% of the capacity. Replace the faulty unit or remove the heavy signal output unit.
