    Why Yamaha Outboard Motor gauge operates unstably?
    • J
      Jason FigueroaSep 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 Outboard Motor trim gauge showing incorrect position?
    • D
      Darrell JenkinsAug 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.

    What causes Yamaha 85AET Outboard Motor fuel management gauge to show incorrect remaining fuel?
    • D
      Dan LeeAug 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.

    • M
      Megan WilsonAug 27, 2025
      If the illumination does not light, it could be due to a lack of electrical power or a damaged gauge. You should try replacing the fuse, connecting the couplers securely, replacing the damaged wire or hub, or replacing the gauge.

      patrick01Aug 26, 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.

    Why Yamaha Outboard Motor PTT unit does not hold the outboard motor up?
    • B
      Bryan MortonAug 25, 2025
      If your Yamaha Outboard Motor's PTT unit isn't holding the motor up, a possible cause is that the manual valve is opened; check the manual valve. Also, there might not be enough PTT fluid, so ensure you add sufficient fluid. Another reason could be PTT fluid leakage; in this case, check the PTT unit for leakage. Finally, the main valves might not be operating, requiring you to disassemble and inspect the PTT unit.
