      If the starter on your Yamaha Outboard Motor won't operate, here are some things to check: * The battery capacity might be weak or low – check the battery condition and use a battery of the recommended capacity. * Battery connections could be loose or corroded – tighten the battery cables and clean the battery terminals. * The fuse for the electric start circuit might be blown – check for the cause of the electric overload and repair it, then replace the fuse with one of the correct amperage. * Make sure the engine stop switch lanyard is attached and the shift lever is in neutral. If these steps don't resolve the issue, the starter components may be faulty, requiring service by a Yamaha dealer.
