Note: When the fuel tank is full, fuel will come out
through the fuel vent. The fuel vent is located on
the port side of the boat.
5. A special keyless fuel cap is supplied.
6. Turn the cap counterclockwise to open the fuel fill.
7. Remove the cap.
8. Put the nozzle in the fuel opening.
STATIC ELECTRICITY CAN BE GENERATED WHILE
FUELING AND CAN CAUSE A FIRE OR EXPLOSION.
TO PREVENT STATIC SPARKS WHEN FILLING THE
TANK, MAKE SURE THE NOZZLE IS IN CONTACT
WITH THE FUEL OPENING.
SPILLED FUEL IS DANGEROUS AND CAN YELLOW
FIBERGLASS OR IGNITE. MAKE SURE YOU DO
NOT SPILL ANY FUEL. IF FUEL IS SPILLED ON
THE DECK, USE A CLOTH TO REMOVE THE FUEL
AND PROPERLY DISPOSE OF THE CLOTH ON
SHORE. IF FUEL IS SPILLED ON THE WATER,
EXERCISE EXTREME CAUTION. FUEL FLOATS ON
TOP OF THE WATER AND CAN IGNITE. IF EXCESS
FUEL IS SPILLED INTO THE WATER, IMMEDIATELY
EVACUATE THE AREA AND NOTIFY THE MARINA
AND THE PROPER OFFICIALS.
9. Fill the fuel tank slightly less than the rated capacity
to allow for expansion to avoid spilling fuel out of the
vents and fuel fills.
10. Remove the nozzle.
11. Install and tighten the fuel cap. Be careful not to
overtighten the cap.
12. Check the fuel compartment and below the deck
for fuel odors. If you smell fuel, do not start the
engine.
TO REDUCE THE RISK OF A FIRE AND/OR
EXPLOSION, DO NOT START THE ENGINE WHEN
FUEL FUMES ARE PRESENT. FUEL FUMES ARE
DANGEROUS AND HARMFUL TO YOUR HEALTH.
MAKE SURE ALL GASOLINE ODORS ARE
INVESTIGATED IMMEDIATELY.
3.4 Fuel System Maintenance
Periodically inspect all primer bulbs, 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 fill cap O-ring seal
with petroleum jelly or silicone grease. The O-ring seal pre-
vents water from entering the fuel system through the fuel fill
cap and it should be immediately replaced if there is any sign
of damage or deterioration.
The fuel vent screens should be clear and free from corrosion
and salt buildup. The screens will prevent insects and other
foreign matter from contaminating the fuel and fuel system.
Fuel vent should be replaced if the vent or screens are dam-
aged or badly corroded. Fuel vent screens that are clogged
will prevent the fuel tank from venting properly and make
filling the fuel tank difficult or cause fuel supply problems to
the engine.
Contaminated fuel may cause serious damage to your engine.
The filter must be checked for corrosion and deterioration
frequently. The filter must be changed at least once a season
or more frequently depending on the type of engine and the
quality of the fuel. Please refer to the engine or fuel filter
manufacturer’s instructions for information on servicing and
replacing the fuel filter.
The age of gasoline can effect 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 the engine 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 recommended for your engine.
Avoid using fuels with alcohol additives. Gasoline that is an
alcohol blend will absorb moisture from the air which can reach
such concentrations that “phase separation” can occur whereby
the water and alcohol mixture becomes heavy enough to settle
out of the gasoline to the bottom of the tank. Since the fuel
pick up tube is very near the bottom of the tank, phase separa-
tion can cause the engine to run very poorly or not at all. This
condition is more severe with methyl alcohol and will worsen
as the alcohol content increases. Water or a jelly like substance
in the fuel filters are an indication of phase separation from the
use of alcohol blended fuels.
