Fuel System
Filling The Fuel Tank:
The fuel cap is designed to be opened by hand
and does not require a key. Press the button
on the side of the cap to open it for fueling.
Make sure the fuel pump nozzle is equipped
with an automatic shuto valve. Then put the
nozzle in the fuel ll opening and make sure it
stays in contact with the fuel ll tting during
the entire fueling operation.
Fill the tank until the nozzle shuto valve clicks
and automatically stops the fuel ow.
Remove the nozzle.
Close and latch the fuel cap.
WARNING
SPILLED FUEL CAN CAUSE A FIRE OR AN EXPLOSION.
MAKE SURE YOU DO NOT SPILL ANY FUEL. IF A SMALL
AMOUNT OF FUEL IS SPILLED ON THE FIBERGLASS, USE A
CLOTH TO REMOVE THE FUEL AND PROPERLY DISPOSE OF
THE CONTAMINATED CLOTH. IF FUEL IS SPILLED ON THE
WATER, EXERCISE EXTREME CAUTION. FUEL FLOATS ON
THE SURFACE OF THE WATER AND CAN IGNITE. IF FUEL
IS SPILLED INTO THE WATER, IMMEDIATELY EVACUATE
THE AREA AND NOTIFY THE MARINA AND THE PROPER
OFFICIALS.
Preparing the Boat for Operation
Use the following procedure to prepare the
boat for operation when fuel operations are
complete:
Open all hatches, windows and doors.
Check the fuel compartment and below the
deck for fuel odors. If you smell fuel, do not
start the engine.
DANGER
GASOLINE FUEL VAPORS THAT ACCUMULATE IN THE
BILGE COMPARTMENT WHILE FUELING CAN EXPLODE!! TO
REDUCE THE RISK OF A FIRE AND/OR EXPLOSION AFTER
FILLING THE FUEL TANK, ALWAYS OPEN ALL HATCHES,
WINDOWS, AND DOORS TO COMPLETELY VENTILATE THE
BOAT BEFORE STARTING THE ENGINE.
5.4 Fuel System Maintenance
Periodically inspect all connections, clamps and
hoses for leakage and damage or deterioration.
Replace as necessary. Spray the valves, tank
fuel gauge sender and ground connections with
a metal protector.
Frequently inspect and lubricate the fuel ll cap
O-ring seal with Teon or silicone grease. The
O-ring seal prevents water from entering the fuel
system through the fuel ll cap and should be re-
placed immediately if there is any sign of damage
or deterioration.
Contaminated fuel may cause serious damage
to your engine. Fuel lters must be checked for
water and other contamination frequently. Engine
lters must be changed at least once each year or
more frequently depending on the type of engine
and the quality of the fuel. Refer to the engine
manufacturer’s instructions for information on
servicing and replacing the fuel lter elements.
The age of gasoline can aect engine performance.
Chemical changes occur as the gasoline ages that
can cause deposits and varnish in the fuel system
as well as reduce the octane rating of the fuel.
Severely degraded fuel can damage engines and
boat fuel tank and lines. Therefore, if your boat
is not being run enough to require at least one
full tank of fresh fuel a month, a fuel stabilizer
should be added to the gasoline to protect the
fuel from degradation. Your dealer or the engine
manufacturer can provide additional information
on fuel degradation and fuel stabilizers recom-
mended for your engine.
In many states, most gasoline is blended with
ethanol alcohol. Ethanol is a strong solvent and
can absorb water during periods of storage. You
should refer to the engine operating manual for
information regarding alcohol blended fuels and
how it aects the operation of your marine engine.
WARNING
AFTER THE FILTER ELEMENT HAS BEEN CHANGED, PRIME
THE FUEL SYSTEM AND CHECK ALL FITTINGS FOR LEAKS
BEFORE AND AFTER STARTING THE ENGINE FOLLOWING
ANY FUEL SYSTEM SERVICE.
