Engine Cooling System

SYSTEM DAMAGE HAZARD!
The engine cooling system's seacocks must be Opened before the engines are started and must
remain Open during engine operation.
• The engine cooling
system circulates
raw water around
components and also
uses a freshwater
heat exchanger on
the engine to reduce
engine temperature.
• Make sure both
engine seawater
intake valves (sea-
cocks) are Open
before starting the
engines and keep the
seacocks Open
while the engines
are running.
• The cooling sys-
tem's seawater
strainers should
be checked for
leaks and debris
every time you use
your yacht.
• For instructions
on how to clean the
seawater strainers,
see the Seawater
Systems section of
this manual.
