Fueling your boat is different that filling up your car. It is common for fuel to splash out of the deck fill, for one thing. Plus, boats usually have a fuel tank vent that can send fuel straight into the water. Avoid these small drops and drips, and save money and the enviroment.
Put out all smoking materials and secure your boat to the dock. Know how much fuel your boat holds and how much you need. Turn off engines and electronics, and extinguish all open flames. Send passengers ashore and close hatches, ports and doors. Remove portable fuel tanks from the boat and fill on the dock. Check that the fuel will be going into the proper fill entry.
Use an absorbent pad or donut around the deck fill to catch spills.Catch spills from the fuel vent with a device such as a “nospill”. Maintain contact between the nozzle and deck fill to prevent sparking. Hold nozzle when refueling; do not use a hands-free clip. Fuel slowly, and listen for a change in tone as the tank gets full. Don’t rely on the automatic shutoff device. Resist topping off. As the temperature rises, fuel expands, so you should actually fill tanks to only 90%. It is dangerous to turn on any electronics while fueling, such as a fuel gauge.
Wipe up all spills and drips and dispose of pads properly. Open ports, hatches, and doors to ventilate. Smell bilges and engines compartment for gas fumes. Operate blower for three to five minutes before starting the engine.
