What to do if my Yamaha Outboard Motor engine will not start?
- EEmily PenaAug 14, 2025
If your Yamaha Outboard Motor engine won't start but the starter is operating, several factors could be at play. First, ensure the fuel tank isn't empty and that you're using clean, fresh fuel. A clogged fuel filter could also be the culprit, so try cleaning or replacing it. Make sure you are following the correct starting procedure. Other potential issues include fouled or incorrect spark plugs (inspect, clean, or replace them), incorrectly fitted spark plug caps (check and refit), poor ignition wiring connections (check for wear, tighten, or replace wires), a missing engine stop switch lanyard (attach it), or damaged internal engine parts or fuel pump malfunctions, which would require servicing by a Yamaha dealer.
