After Fueling Your Boat
After fueling:
- Put the fill cap on tightly to prevent vapors from escaping.
 - Open all windows, ports, doors, and other openings.
 - If your boat is equipped with a power ventilation system (exhaust blower), turn it on for at least four minutes before starting your engine. This will help eliminate fuel vapors in the bilge.
 - Before starting the engine, sniff the bilge and engine compartment for fuel vapors. Continue ventilating until you cannot smell any fuel vapors. Consider installing a gas vapor detection and alarm device.
 - Start the engine and then reload your passengers.
