If your Yamaha Boat's engine runs irregularly or stalls, there could be several reasons: * **Fuel issues:** Refill the fuel tank as soon as possible. If the fuel is stale or contaminated, have it serviced by a Yamaha dealer. * **Spark plug problems:** Replace the spark plug if it's faulty or has an incorrect heat range. Adjust the gap if it's incorrect. Ensure the spark plug cap is properly connected. If the cap is cracked, torn, or damaged, have it serviced by a Yamaha dealer. * **Other issues:** For electrical wiring or fuel injection system problems, it's best to have your boat serviced by a Yamaha dealer.
