Why is the warning buzzer sounding on my Yamaha F50C Outboard Motor?
- D
  David SmithAug 12, 2025
  If the warning buzzer sounds or the indicator lamp lights on your Yamaha Outboard Motor, it could be due to several reasons. Check the water intake for any restrictions, as the cooling system might be clogged. Ensure the engine oil level is adequate and that you're using the specified engine oil. Also, the spark plug's heat range might be incorrect, so inspect and replace it if necessary. Other potential causes include contaminated or deteriorated engine oil (replace it), a clogged oil filter, or improperly distributed load on the boat (distribute the load evenly). For issues like a faulty water pump/thermostat or oil feed/injection pump malfunctions, it's best to have it serviced by a Yamaha dealer.

How to fix a Yamaha F50C when the starter will not operate?
- A
  Angela JonesAug 18, 2025
  If your Yamaha Outboard Motor's starter won't operate, begin by checking the battery condition and ensuring it has the recommended capacity. Weak or low battery capacity can prevent the starter from functioning. Next, inspect the battery connections for looseness or corrosion; tighten the cables and clean the terminals if needed. Also, verify if the fuse for the electric start circuit is blown and replace it with the correct amperage after identifying and fixing the cause of the overload. Ensure 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.

Alternatively, the propeller shaft could be damaged, requiring service by a Yamaha dealer. Check for weeds or foreign matter tangled on the propeller and remove them. Ensure the motor mounting bolts are tightened. If the steering pivot is loose or damaged, tighten it or have it serviced by a Yamaha dealer.
