Although the boat engine is similar to an automo-
bileengine,theenginecompartmentdierssub-
stantially. The underside of an automobile engine
compartment is totally open to the atmosphere. This
allows complete air circulation and ventilation. A
boat engine is housed in a closed compartment, the
undersideofwhichisthebottom(hull)oftheboat.
The enclosed engine compartment limits the
ventilationofgasolineandoilfumes.Because
confined gasoline vapors mixed with a little air can
form an explosive atmosphere, it is important to be
especiallyvigilantinperformingthefollowingtwo(2)
operations:
Step 1: Inspect the boat bilge area under the engine
for the evidence of oil and gasoline—or any
gasoline odor. This inspection should take
place the first time the boat is started each
day.Raisetheenginecoverandvisuallylook
at the bilge area under the engine.
Step 2: Runthebilgeblowerforatleastfour(4)minutestoventilatethebilgeareaeach
time before starting the engine.
Gasoline is explosive. If a gasoline odor is
present or gasoline is visually observed in
the bilge area during inspection, DO NOT
START YOUR ENGINE! Remove the ignition
key from the ignition switch and call an
authorized MasterCraft dealer for service.
Note: If there is evidence of loose fuel fittings, deteriorated lines or other problems as-
sociated with the fuel system, call an authorized MasterCraft dealer. Fuel system service
on later-model MasterCraft boats requires special service tools and special training. Due
to the potential for serious consequences when errors occur in servicing the fuel system,
MasterCraft strongly encourages all boat owners and operators to seek professional assis-
tance from an authorized MasterCraft dealer’s service department whenever any service or
perceived problems occur within the fuel system.
All replaced fuel components must meet
United States Coast Guard (“USCG”) and
American Boat & Yacht Council, Inc.
