IPS Engines
Your yacht is powered by twin IPS inboard engines. All operation,
specification and maintenance information is contained in the engine
owner’s manual. Find this manual, located in the Skipper’s Kit, and
familiarize yourself with it. The engines are the heart of your yacht,
and following the manufacturer’s recommendations will provide you
with continued boating pleasure. The IPS (Integrated Propulsion
System) is a fully integrated propulsion system. The controls,
propulsion, rudder and steering system are all integrated. The
engine’s power is transferred through the hull and into the IPS drive
units beneath the hull.
Engine Ignition Starting / Stopping - Key Switch
Your Cruisers Yacht may be equipped with key switch STARTING/
STOPPING switches. This type of switch works on the same principle
as an automobile. Refer to the engine owner’s manual in the Skipper’s
Kit for complete details.
Transmission
Through a series of gears, the transmission transmits the motive force
of the engine to the propeller. The transmission has one forward and
one reverse speed, and is shifted by the transmission selector on the
dash. All the operation, specification and maintenance information is
contained in the engine owner’s manual.
Cooling System
The IPS system is cooled by seawater entering water pickups
integrated in the IPS system. The water enters the engine through the
engine water jacket and is returned to the sea through the exhaust
system.
A feature which is standard on diesel engines is the freshwater
cooling system. This system uses the incoming seawater to cool a
secondary closed-cooling system. The seawater flows through an
engine-mounted heat exchanger, cools the closed-system coolant
and is returned to the sea via the exhaust system.
ALARM SYSTEMS
Alarm systems are on all boats. The alarm will sound under the
following conditions:
• Engine temperature exceeds specified limits
• Engine oil pressure drops below specified limits
• Transmission oil temperature exceeds specified limits and level is
low
• Ignition switches are ON, engines are OFF
To test the alarm system, turn the ignition switch to the ON position.
Depending upon the engine, the alarm may sound immediately, or
after a few seconds’ delay.
CAUTION
The cooling system starts at the cooling water
seacock. The seacocks can be closed during storage,
or to prevent water from entering the yacht in the
event of hose failure. Make sure the seacocks are
open before starting engines. The absence of cooling
water will cause the engines to overheat and cause
irreparable damage.
