NOTICE
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
specifications.
The gasket seal on the fuel fill cap assists in sealing
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.
A. System Testing
DO NOT confuse GAS deck fill plate with
WATER or WASTE deck plates. Deck fill plates
are labeled according to the intended use.
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 per-
formed 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.
Prior to taking delivery, it is important that a full in-
spection be made of the entire fuel system by the sell-
ing dealer. An entry on the Four Winns® Pre-Delivery
Inspection Form portion of the Warranty Registration
Card will attest to the dealer’s performance of this
service.
NOTICE
When fueling at a marina, DO NOT overfill.
Fuel may spill into the water.
B. Fuel Fills
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 addi-
tional 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
fiberglass. It will also damage the tape stripes and
logos.
The fuel fill fitting allows for venting below the fill cap.
While the tank is being filled, the air displaced by the
fuel escapes through the fuel fill/vent. This reduces
