Engine
Read and understand the engine operation and maintenance manuals before using or working on the engines.
Engine Cooling System
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 (seacocks) are Open before starting the engines and keep the
seacocks Open while the engines are running.
•
The cooling system’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 man-
ual.
SYSTEM DAMAGE HAZARD!
The engine cooling system’s seacocks must be Opened before engines are started and during
engine operation.
