Each propulsion engine has a closed cooling system that removes heat from the engine
and exhaust system . Closed systems use a freshwater/antifreeze mixture to cool the en-
gine . The coolant mixture runs through a heat exchanger that transfers heat to seawater
taken in through a seacock for each engine .
Make sure that a sufficient level of coolant mixture is kept in each system .
Open the
cooling system seacocks before starting the engines.
The inlet seacocks for each
engine are located on the IPS drives .
Clean the seawater strainer (located on the AFT PORT of the engine) every 14 days or
sooner as necessary . Running an engine with an inadequate supply of antifreeze, or with
obstructed or restricted seawater pickups or strainers can cause serious damage to the
engine and related systems .
The cooling system may need to be repaired if an above normal temperature registers on
the engine temperature gauge . IMMEDIATELY shut off the affected engine if the engine
temperature quickly rises, and have the cooling system inspected and repaired .

Check the exhaust system regularly for proper operation . Change in engine noise could
indicate an exhaust system problem, and should immediately be investigated .
The exhaust system for each engine consists of an exhaust manifold, exhaust piping,
and the exhaust hoses used to vent the exhaust to the atmosphere . Carbon monoxide
may escape and endanger the passengers if the exhaust system contains leaks or
obstructions, or has any other problem that prevents it from venting exhaust properly .

An automatic fire suppression system is installed in the engine room . The suppression
system is located forward of the port engine between fuel tank and waste tank . The
system provides extra security in the event of an engine room fire . Refer to the OEM
information for details on operating the fire suppression system . The system can also be
activated manually by a handle mounted at the Aft PORT Locker .
