Why does my Yamaha Outboard Motor fuel management gauge show incorrect remaining fuel?
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 doesn't my Yamaha Outboard Motor boat speed gauge show?
If the boat speed and/or coolant pressure gauge isn't showing, it means the optional sensor hasn't been installed. Install the optional sensor to fix this.
How to setup Yamaha 20DMH Outboard Motor tachometer to show the oil pressure?
Select the oil press. display.
How to fix Yamaha 20DMH Outboard Motor tachometer showing incorrect engine RPM?
If the tachometer shows an incorrect engine RPM, the engine recognition might be wrong (especially for multi-applications). To correct this, push the 'SET' button for 10 seconds to default the engine number, then memorize each engine number again.
What causes Yamaha 20DMH Outboard Motor fuel management gauge to show incorrect remaining fuel?
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.
What to do if Yamaha 20DMH gauge shows “----”?
If the gauge displays '----', it indicates that the digital signal is not being received. Check that the couplers are securely connected and replace any damaged bus wires or hubs.
Why Yamaha Outboard Motor Speedometer or Comb. Speedometer & Fuel mgt gauge shows incorrect fuel level?
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.
Why is my Yamaha Outboard Motor gauge operating unstably?
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.
Why does my Yamaha 20DMH Outboard Motor trim gauge show the incorrect position?
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.
What to do if my Yamaha Outboard Motor gauge display does not wake up?
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.
