Make sure that a sufcient 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 labeled ENGINE WATER SUPPLY.
Clean the seawater strainer (located on the FORWARD INBOARD of each engine) every 14 days or sooner as necessary.
NOTICE: Serious damage to the engine and related systems can occur by running an engine with an inadequate supply
of anti-freeze or obstructed seawater pickups or strainers.
The cooling system may need to be repaired if an above-normal temperature registers on the engine temperature gauge. If
the engine temperature rises quickly, immediately shut off the affected engine, and have the cooling system inspected and
repaired.
ENGINE ROOM VENTILATION: DIESEL ENGINES
The engine room is equipped with a ventilation system that consists of intake ducts, exhaust ducts and bilge blowers. The
ventilation system is designed to remove fuel vapor and excess heat from the engine room. The bilge blowers operate
when the engines are running, as long as BILGE BLOWER 1 through BILGE BLOWER 4 and bilge blower relay circuit
breakers are ON, which are located on the DC control center.
