How to fix Yamaha 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 E40JMH 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 Outboard Motor 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.
What to do if my Yamaha Outboard Motor speedometer shows the incorrect fuel level?

Why Yamaha E40JMH boat speed and/or coolant pressure gauge does not show?
If the boat speed and/or coolant pressure gauge does not show, it is likely that the optional sensor has not been installed. Install the optional sensor.
What causes Yamaha E40JMH Outboard Motor gauge response to be poor or down?
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.
What to do if Yamaha Outboard Motor trim gauge always shows fully tilted up position?
