How long should blower be on after fueling boat?

After fueling a boat, the blower should typically be run for at least 4-5 minutes to ensure that any vapors have been cleared from the engine compartment. This helps to prevent potential fire hazards from gasoline fumes. Always refer to the manufacturer’s guidelines for specific recommendations regarding the blower operation. Additionally, it's important to check for any visible signs of fuel leaks before starting the engine.
