Why Yamaha 75AET Outboard Motor PTT unit does not hold the outboard motor up?
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.
What to do if the Yamaha 75AET 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, if necessary, replace the gauge itself.

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.
How to fix Yamaha 75AET 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.
Why does my Yamaha 75AET Outboard Motor fuel management gauge show incorrect fuel consumption?
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.
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.
Why is the illumination not lighting on my Yamaha 75AET gauge?
