What to do if my Yamaha 25A starter will not operate?
- AAshley TaylorAug 14, 2025
If the starter on your Yamaha Outboard Motor isn't working, several factors could be the cause. First, check the battery condition and ensure it has the recommended capacity. Weak or low battery capacity can prevent the starter from operating. Also, inspect the battery connections for looseness or corrosion; tighten the cables and clean the terminals if needed. A blown fuse in the electric start circuit could also be the culprit; check for any electric overload, repair it, and replace the fuse with one of the correct amperage. Other potential issues include faulty starter components (have it 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).
