What to do if my Yamaha Outboard Motor engine will not start?
- JJared SheltonAug 6, 2025
If your Yamaha Outboard Motor engine won't start, possible causes include an empty or contaminated fuel tank (fill with clean, fresh fuel), a clogged fuel filter (clean or replace it), incorrect starting procedure (consult the 'STARTING ENGINE' section), malfunctioning fuel pump, fouled or incorrect spark plugs (inspect, clean, or replace), incorrectly fitted spark plug caps (check and refit), poor ignition wiring (check for wear, tighten connections, replace if needed), faulty ignition parts, unattached engine stop switch lanyard (attach it), or damaged engine inner parts. For fuel pump malfunctions, faulty ignition parts, or damaged engine inner parts, have your motor serviced by a Yamaha dealer.
