    What to do if Yamaha 115CETO fuel management gauge shows incorrect fuel consumption?
    • T
      Tiffany TaylorAug 19, 2025
      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.

      Stacy CarrollAug 21, 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, if necessary, replace the gauge itself.

    • G
      guzmanlaurieAug 28, 2025
      If the fuel management gauge shows incorrect remaining fuel, the fuel capacity setting may be wrong (specifically for SQR Fuel mgt Gauge). Fill the tank with fuel, and set the correct fuel tank capacity.

    Why Yamaha Outboard Motor Speedometer or Comb. Speedometer & Fuel mgt gauge shows incorrect fuel level?
    • S
      sandysimpsonSep 2, 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.

    How to fix Yamaha 115CETO trim gauge showing incorrect position?
    • A
      Adriana PerezSep 4, 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 Outboard Motor gauge operates unstably?
    • K
      kristopher85Sep 6, 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.

    What causes Yamaha Outboard Motor gauge response to be poor or down?
    • D
      dennisjeremySep 9, 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.
