capacities.
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.

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.
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

DO NOT confuse GAS deck fill plate with
WATER or WASTE deck plates. Deck fill plates
are labeled according to the intended use.
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.
NOTICE
When fueling at a marina, DO NOT overfill.
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.
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.
