ECTION

A gentle twist of the joystick allows you to make a
360 degree turn. Push the joystick in any direction,
forward, backward, diagonal and even sideways
and the yacht will follow the command. Refer to the
Zeus propulsion operator’s manual for more
detailed operation of the system.
Steering Wheel
The steering wheel uses the assistance of power
steering, which allows you to turn the steering
wheel with minimum effort. It is very important that
you know how your steering affects the operation of
your yacht and be aware of its limitations.
Fuel System
The fuel system consists of permanent tanks with
an air vent system, fuel level sensors and fuel fill
components. In case of a fuel leak or fire, both
tanks have shutoff valves. The entire fuel system
can be filled from either the port or starboard fill
fitting provided the crossover valve is left in the
open position (See Systems Summary, page 4).
Ventilation System
The engine compartment ventilation system
consists of blowers installed in the engine
compartment. These blowers come on
automatically with engine ignition or can be
activated by switch.
Electrical Systems
Your Cobalt yacht is equipped with two electrical
systems. A direct current (DC) system is battery
powered and supplies electricity to lights, pumps,
blowers, engine ignition and sometimes a
refrigerator. An alternating current (AC) system is
shore power, or generator, and supplies electricity
to the electrical outlet, air conditioning, battery
charger and other 110V AC or 220V AC appliances
or components.
Cooling System
The engines and generator are cooled by the
continuous intake of raw water through
independent water intakes. The water flows to
water pumps on the engines and/or generator for
circulation around internal components. The engine
water intakes and outlets are located in the
propulsion system on Zeus-equipped yachts, while
inboard, V-drive yachts and the generator water
intakes are located in the bottom of the hull. The air
conditioner intake is also in the bottom of the hull
and exits from the side. If your Cobalt yacht is
equipped with a self-contained cooling system, a
mixture of fresh water and antifreeze is pumped
through a large heat exchanger to reduce
temperatures. Raw water is circulated through the
other side of the heat exchanger to dissipate heat
absorbed by the coolant mixture.
Exhaust System
The engine and generator exhaust systems remove
the gases produced by the running engines and
vents them away from the yacht. The generator
exhaust is expelled on the sides of the yacht.
Engine exhaust is expelled below the waterline
through the outdrives. Engine and generator
cooling water are also removed along with the
exhaust gases.
A
WARNING
ASK THE CAPTAIN BEFORE ENTERING
THE WATER.
This boat has a feature called Skyhook,
which automatically holds the boat in
position.
When Skyhook is activated:
• the propellers rotate automatically.
• propeller rotation may not be obvious.
• the boat may suddenly move in any
direction.
• the propellers can injure people in the
water anywhere around the boat.
Unless the Captain gives you
permission:
• do not go in the water; wind or water
current can move swimmers into the
propellers.
• do not sit or stand where you could fall
overboard; you may lose your balance
if the boat moves suddenly.
