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

      Christian WrightSep 7, 2025
      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.
