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 ll plate with
WATER or WASTE deck plates. Deck ll plates
are labeled according to the intended use.
Spilled fuel is a re hazard. DO NOT overll
or overow 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.
NOTICE
When fueling at a marina, DO NOT overll.
Fuel may spill into the water.
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.
DO NOT TOP OFF.

boats are
designed to meet or exceed the requirements of the
U.S. Coast Guard, the National Marine Manufacturers
Association, and the American Boat and Yacht
Council in effect at the time of manufacture.

NOTICE
Use only clean fuel of the type and grade
recommended by the engine manufacturer.
Engine damage resulting from the use of a
l
ower 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
specications.
A. System Testing
All gasoline fuel systems have been factory inspected
and pressure tested in accordance with regulations
i
n effect at the time of manufacture. Additionally,
each fuel tank must pass rigid tests and inspections
performed by the fuel tank manufacturer.
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.
B. Fuel Fills
Fuelll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.
