5.1.5 Fuel Shut-Off Valves

Fuel shut-off valves are included with the fuel system:
The fuel supply line valves must be open when operating the engines.

5.2 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 oper-
ate whenever the engines are running, as long as the four Bilge Blower
circuit breakers on the Bridge Breaker Panel are "ON."
You are responsible for keeping the engine room ventilation system in
proper operating condition. Inspect the intake and exhaust ducts regu-
larly 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.
Operate the blowers for at least 4 minutes and until the engine room is
free of any fuel vapor before starting the engines or the generator.

5.3 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. If you are not sure
which type of cooling system is installed on your boat, contact your
Carver Dealer.
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 en-
gines. The seacock and strainer for each engine's cooling system is
located aft of the engine. Refer to 9.7.4 Engine Room for the exact
location of the seacocks and strainers. If the engines have closed

• Fuel supply line valves are located on the top of the fuel tanks on the
aft inboard side.
• Fuel transfer line valves (diesel systems only) are located on the
bottom of the fuel tanks near the aft inboard corner.
