Why Yamaha 50G starter will not operate?
- A
  Alison HaleAug 1, 2025
  If your Yamaha Outboard Motor's starter won't operate, several factors could be at play. The battery capacity might be weak or low, requiring you to check its condition and potentially use a battery with the recommended capacity. The battery connections could be loose or corroded; ensure you tighten the battery cables and clean the terminals. A blown fuse in the electric start circuit could also be the culprit, so check for any electric overload, repair it, and replace the fuse with one of the correct amperage. Other potential causes include faulty starter components (have these serviced by a Yamaha dealer), the engine stop switch lanyard not being attached (attach the lanyard), or the shift lever being in gear (shift to neutral).
