    Why does my Yamaha 85AET fuel management gauge show incorrect fuel consumption?

      Michael HardySep 12, 2025
      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.

      If the PTT motor on your Yamaha Outboard Motor isn't working, start by checking the battery terminal for loose connections. Also, ensure the battery isn't discharged. Inspect the fuse (20A) to see if it has blown. Then, check the PTT motor lead and ground circuit for any shorts, opens, or loose connections. Finally, if none of those are the cause, you may need to disassemble and check the PTT motor itself for a malfunction.
