Boating Basics: Before Going Out on Your Vessel

Fueling a Vessel

Here are some safe fueling procedures to follow:

• Check the entire fuel system for leaks. Tighten connections frequently. Engine vibration can loosen them.
• Turn off all engines and electrical equipment; shut off all fuel valves; and close all windows, doors and openings.
• Try to fuel in daylight. If light is required, use a flashlight or a light that is spark-proof.
• Never smoke or strike a match while fueling.
• When filling a tank or gas can, follow these guidelines:
  • Remove portable tanks from the vessel.
  • Touch the fuel pipe or tank with the spout to prevent buildup of static electricity.
  • Never fill a tank to the brim. Leave room for gas to expand. After fueling, put the fuel cap on tightly to prevent vapors from escaping.
  • Immediately wipe up any spilled gas. Air out the rag after using it. Never throw it in the vessel or the water.
  • Store gas on board in a safety-approved storage tank, away from the engine in an area of good ventilation.

The most important safe fueling practice … If your vessel is equipped with a power ventilation system, turn it on for at least four minutes after fueling, prior to starting your engine to remove gas vapors.

Some additional safety procedures for PWCs are:

• Avoid spills when fueling in or near the water.
• After fueling, open the door of the engine compartment and sniff to check for any evidence of gas fumes. Do this before starting the engine. If you do smell gas fumes, find the source and make repairs immediately.
• Do not tip the PWC to “fill all the way up.” The tank provides for fuel expansion; if tank is over-filled, gasoline may expand and spill into the water.
