Section 6 Cooling System
6.1 Direct Water Cooled
In a direct seawater cooling system, the impeller pump
circulates the seawater around the cylinder and through
the cylinder head. A thermostat controls the cooling water
circuit temperature. Consult Figure 6-1 and the engine
operation manual for the cooling water circuit diagrams.
NOTICE
Saltwater damage. Saltwater quickly deteriorates metals.
Wipe up saltwater on and around the generator set and
remove salt deposits from metal surfaces.
