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 forward of the engine. Refer to 9.7.4 Engine Room for the
exact location of the seacocks and strainers. If the engines have
closed cooling systems, make sure that you have a sufficient level of
coolant in each system.
