Each fuel tank, for both gasoline and diesel fuel sys-
tems, is vented overboard. As the fuel tank is filled, air
is displaced from inside the tank and escapes through
the vent.
Your boat's engine room is equipped with a ventilation
system consisting of intake ducts, exhaust ducts and
bilge blowers. This system is designed to remove any
fuel vapors from the engine room before you start the
engines or generator.
Always run the bilge blowers for at least 4 minutes
before starting the boat's engines or the generator.
After fueling and before starting the engines or genera-
tor:
1. On the Bridge Breaker Panel, switch the Main
circuit breaker "ON", then switch the two Bilge
Blower circuit breakers "ON".
2. Turn "ON" the bilge blowers using the controls on
the helm instrument panel. Allow the blowers to
run for at least four minutes. Do not turn "OFF"
the blowers yet.
3. Inspect the engine room. If you smell any fuel
vapor, wait another four minutes so that the bilge
blowers can remove the vapor. Repeat this step as
many times as is necessary until the engine room is
free of fuel vapor. Do not operate any onboard
equipment until you are sure that the boat is free of
fuel vapor.
4. Leave the blowers "ON" while operating the boat
below cruise speed. The blowers help disperse
excess heat in the engine room and also prevent the
accumulation of CO which may occur under some
operating conditions.
Never obstruct or modify the engine room ventilation
system in any way.
