330 SPORT YACHT
GASOLINE FUEL VAPORS THAT ACCUMULATE IN
THE CABIN OR ENGINE COMPARTMENT WHILE
FUELING CAN EXPLODE!! TO REDUCE THE
RISK OF A FIRE AND/OR EXPLOSION AFTER
FILLING THE FUEL SYSTEM, ALWAYS RUN THE
BLOWER FOR AT LEAST FOUR (4) MINUTES AND
OPEN ALL HATCHES, WINDOWS, AND DOORS
TO COMPLETELY VENTILATE THE BOAT BEFORE
STARTING THE ENGINES.
3.6 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 senders and ground connections with
a metal protector.
Frequently inspect and lubricate the fuel fi ll cap
O-ring seal with petroleum jelly or silicone grease.
The O-ring seal prevents water from entering the
fuel system through the fuel fi ll cap and it should
be replaced immediately if there is any sign of
damage or deterioration.
Contaminated fuel may cause serious damage to
your engines. The fi lters must be checked for wa-
ter and other contamination frequently. Gasoline
engine fi lters must be changed at least once each
year and diesel engine fi lter elements must be
changed at least twice a year or more frequently
depending on the type of engine and the quality
of the fuel. Please refer to the engine or fuel fi lter
manufacturer’s instructions for information on
servicing and replacing the fuel fi lter elements.
Algae can grow in the accumulated water in die-
sel fuel tanks. This condition is most prevalent in
warm climates. Periodically adding a high quality
diesel fuel additive containing an algaecide may
be required to control algae in your boating area.
Since algae also can grow in accumulated water
in the fuel fi lters, it is important to run the main
engines and the generator for at least 30 minutes
after the algaecide has been added so it will be
circulated throughout the fuel system. This is
even more important during periods of storage or
if the boat is not used enough to require refueling
at least once a month.
Severe algae in a diesel fuel system can be ex-
tremely diffi cult and expensive to clean. You
should be diligent in monitoring the fuel system by
checking the fi lters for water frequently and being
alert for signs of algae in fuel that is drained from
the fi lters. Most algae appears as black, carpet-
like fi bers suspended in fuel and water drained
from the fi lters. Severe cases of algae will produce
a black jelly like substance that quickly clogs the
fi lters and starves the engines for fuel.
Please contact your Monterey dealer or engine
manufacturer for additional information regarding
fuels and additives.
Note: Diesel engines circulate far more fuel
than they consume. Therefore, it is
extremely important that the fuel
fi lters are checked for water and ser-
viced frequently on boats equipped
with diesel engines.
The age of gasoline can affect 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 recom-
mended 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 separation 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 fi lters is
an indication of phase separation from the use of
alcohol blended fuels.
LEAKING FUEL IS DANGEROUS AND CAN CAUSE
A FIRE AND/OR EXPLOSION. AFTER THE FILTER
ELEMENT HAS BEEN CHANGED, PRIME THE FUEL
SYSTEM AND CHECK ALL FITTINGS FOR LEAKS
BEFORE AND AFTER STARTING THE ENGINES.
DO NOT DRAIN ANY FUEL IN THE BILGE. THIS
COULD LEAD TO A FIRE OR EXPLOSION. CHECK
ALL FUEL LINE FITTINGS FOR LEAKS BEFORE
AND AFTER STARTING THE ENGINES FOLLOWING
ANY FUEL SYSTEM SERVICE.
