water to provide cooling for the closed cooling
and exhaust systems on the generator. You
should also check the exhaust port for water fl ow
each time the generator is started. If there is no
discharge within thirty seconds, shut down the
generator and fi nd and correct the problem.
Note: Generators consume DC electrical cur-
rent and charge the house / generator
battery just enough to compensate for
the DC electrical current the engine
requires to operate. Therefore, it is
important to activate the battery char-
ger to maintain the house and engine
batteries whenever the generator is
running.
Note: The generator may not be able to op-
erate all 120-volt accessories at the
same time. POWER MANAGEMENT
PRACTICES may need to be observed
depending on the AC power load.
Cleaning the Sea Strainers
• Turn off the engines and generator.
• Close the generator water intake valve.
• Open the top of the strainer and remove the
screen.
• Thoroughly fl ush the screen and the inside of
the strainer to remove foreign matter.
• Lubricate the seal.
• Reassemble the strainer making sure that all
fasteners are tight.
• Open the intake valve.
• Start the generator and inspect the strainer
for leaks.
The generator fuel system is equipped with a water
separating fuel fi lter and operates much like the
fuel system for the main engines. Please refer to
the Fuel System chapter for more information on
generator fuel system.
You also should read the generator owner’s man-
ual for detailed information on the safe operation
and maintenance of the generator.
GENERATOR ENGINES PRODUCE CARBON
MONOXIDE WHICH IS A LETHAL, TOXIC GAS
THAT IS COLORLESS AND ODORLESS. IT IS A
DANGEROUS GAS THAT WILL CAUSE DEATH
IN CERTAIN LEVELS. ONLY OPERATE THE
GENERATOR IN WELL VENTILATED AREAS AND
NEVER OPERATE THE GENERATOR WHILE YOU
ARE SLEEPING.
4.5 Bonding System
Your boat is equipped with a bonding system
that interconnects all underwater metal hardware
and thru-hull fi ttings to ensure that they are of
the same electrical potential. Zinc anodes are
attached to the bonding system at the transom
plates and outdrives. The Zinc anodes deteriorate
before the other metals, thereby protecting the
underwater metals from galvanic corrosion or stray
electrical current. Since the zincs are sacrifi cial, it
is important to monitor them and replace the zincs
when they have deteriorated to 50 - 75% of their
original size. The bonding system is connected
to the DC ground and the earth ground wire for
the AC electrical system. It provides a path to
the safety earth ground in the event of a fault in
the shore earth ground connection and when the
boat is away from the dock.
4.6 Electrical System Maintenance
12-Volt AC Electrical System Maintenance
At least once a year, spray all exposed electrical
components behind the helm and in the plugs,
with a protector. Exterior light fi xture bulbs should
be removed and the metal contact areas coated
with a non-water soluble lubricant like petroleum
jelly or silicone grease. The sockets should be
sprayed with a protector. Care must be taken not
to get any oil or grease on the glass portion of
the bulbs as this will cause the bulb to overheat
and burn out.
WHEN REPLACING LIGHT BULBS IN MARINE
LIGHT FIXTURES, ALWAYS USE A BULB WITH
THE SAME RATING AS THE ORIGINAL. USING A
DIFFERENT BULB COULD CAUSE THE FIXTURE TO
OVERHEAT AND MELT OR SHORT CIRCUIT.
