Figure I-1:  Fuel Fill
Use only clean fuel of the type and grade
recommended by the engine manufacturer.
Engine damage resulting from the use of a
lower octane gasoline is considered misuse
of the engine and will void the engine warranty.
Refer to the section on Gasoline Requirements
in the engine manual for information on octane
The gasket seal on the fuel fill cap assists in seal ing
when closed. A missing or damaged gasket can allow
water on the surrounding surfaces to run into the tank.
Periodically inspect the gasket and the fuel deck plate
for damage.
DO NOT confuse GAS deck fill plate with
WATER or WASTE deck plates. Deck fill plates
are labeled according to the intended use.
A.   System Testing
All gasoline fuel systems have been factory inspected
and pressure tested in accordance with regulations
in effect at the time of manufacture. Additionally,
each fuel tank must pass rigid tests and inspections
performed by the fuel tank manufacturer.
Spilled fuel is a fire hazard. DO NOT overfill
or overflow the tank, or allow fuel spills into
the hull or bilge. If spillage occurs, clean up
immediately and dispose of soiled rags/towels
in a proper container.

Fuel fill deck plates are located either on the aft deck
or side decks, and are marked “GAS”. To open, insert
the deck plate key into the holes on the cap and rotate
counterclockwise. A bead chain connects the cap to
body to help prevent loss overboard. Be sure to utilize
the proper type and grade of fuel as recommended by
the engine manufacturer. See Section I-2 for
additional information.
Avoid overboard spills. When tank is almost full
the sound from the fuel vent will change. The
pitch will become higher indicating the tank is
close to being full. Stop pumping fuel into tank.
After fueling, replace the fill cap, and wash the areas
around the fuel fill plate. Residual fuel left on the deck
and hull sides can be dangerous, and will yellow the
fiber glass. It will also damage the tape stripes and
The fuel fill fitting allows for venting below the fill cap.
While the tank is being filled, the air dis placed by the
fuel es capes through the fuel fill/vent. This reduces
