Engine Room ventilation
Your boat’s engine room is equipped with a ventilation system consisting
of intake ducts, exhaust ducts and bilge blowers. This system is designed
to remove any fuel vapor from the engine room. The bilge blowers operate
whenever the engines are running, as long as the four Bilge Blower circuit
breakers on the DC Control Center are ON.
You must keep the engine room ventilation system in proper operating
condition. Inspect the intake and exhaust ducts regularly to make sure they
are free of obstructions and have not collapsed or torn. Inspect the blowers
to make sure they are operating properly. Replace any worn components
with new components of the same type.
Cooling System
Each propulsion engine has a cooling system which removes excess heat
from the engine and its exhaust system. Closed systems use a freshwater/
antifreeze mixture to cool the engine. The coolant runs through a heat
exchanger where the excess heat is transferred to seawater taken in
through a seacock for each engine. Open cooling systems use seawater to
cool the engines directly. More detilas on next page.
Both open and closed cooling systems require seawater to function. Before
each cruise, make sure the cooling system seacocks are closed, then
make sure the optional strainers are free of seaweed and other debris.
Open the cooling system seacocks before you start your engines.
If the
engines have closed cooling systems, make sure that you have a sufficient
level of coolant in each system.
If you intend to operate the boat with only one engine running, you must first close
the cooling system seacock for the engine that will not
be running. Failure to do so
