  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.

  If the starter on your Yamaha Outboard Motor isn't working, here are a few things to check: 1. Make sure the battery isn't weak or low. Check its condition and use a battery with the recommended capacity. 2. See if the battery connections are loose or corroded. Tighten the cables and clean the terminals. 3. Check if the fuse for the electric start circuit has blown. If it has, find out what caused the overload and repair it before replacing the fuse with one of the correct amperage. 4. Ensure the engine stop switch lanyard is attached. 5. Confirm the shift lever is in neutral. If these steps don't solve the problem, starter components may be faulty and should be serviced by a Yamaha dealer.
