Fuel Management
Use the “one-third” rule for fuel management. Use one-third of the fuel to reach
your destination, one-third to return and one-third as reserve fuel.
Fueling
The fuel filler on boats with built-in tanks is usually located in the aft area. The fuel
tank is equipped with either a shutoff valve or antisiphon valve. The shutoff valve
requires you to manually turn the fuel valve, while the antisiphon valve operates
automatically. Because gasoline fumes are heavier than air, they will sink to the
lowest part of your boat, such as the bilge. Always evacuate fumes with the bilge
blower (if equipped) before attempting to start the engine.
NOTICE: To prevent unwarranted engine damage, see your Engine Operator’s
Manual for manufacturer-recommended fuel and oil specifications.
When refueling, observe the following:
• Have a proper and charged fire extinguisher ready.
WARNING!
Gasoline is
extremely flammable and highly explosive under certain conditions. See
Safety on page 2-1 for more details.
• Secure the boat to the dock.
• Stop all engines, motors and fans before refueling.
• Never smoke or allow open flames or sparks within 50 feet (15 meters) of the
fueling area.
• Avoid spills and know how much fuel is already in the tank before adding fuel.
Wipe up any spills immediately.
• Always fill fuel tanks slowly. Be aware that if the boat’s attitude changes while
floating, the fuel level and position change in the tank, which could cause
spillage.
• Never overfill the fuel tanks.
• Always allow space (at least 6%) for expansion of fuel in the fuel tank.
• Always be sure you are filling the proper tank; some deck filler plates appear
similar to the fuel tank.
• Never pump fuel into an unapproved container.
• Use only fuel approved by the engine manufacturer.
• Check for fuel leaks.
• Refuel only at safe and approved filling stations such as marina fuel docks or
automotive fuel stations. Approved venues have safeguards in place to lessen
the likelihood of static discharge.
• Read and follow all warnings on the pump or in the vicinity of the pump.
• Maintain contact between the fuel nozzle and the fill pipe at all times, before and
during refueling, to prevent an electrostatic spark.
• Be aware of the fuel tank vent to avoid splash-back and fumes during refueling.
