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.
Before each cruise, make sure the cooling system seacocks are closed,
then make sure the strainers, located near the seacocks, are free of
seaweed and other debris. Open the cooling system seacocks before you
start your engines. The seacock for each engine’s cooling system is lo-
cated in the engine room aft of the engine. Refer to 9.7.4 Engine Room
for the exact location of the seacocks and their strainers. If you have a
closed system, make sure that you have a sufficient level of coolant in the
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 can flood the non-running engine with seawa-
ter, damaging it. Before you restart the non-running engine, open its
seacock again.
Running an engine with an inadequate supply of antifreeze, or with
obstructed or restricted seawater pickups or strainers can cause serious
damage to the engine and its related systems.
After starting your engines, check the engine exhaust outlets. Refer to
9.7.3 Thru-Hull Fittings for the location of the engine exhaust outlets.
If water is not being ejected from the outlets, immediately shut down the
engines. Determine why seawater is not being pumped through the
system. Have the problem corrected before restarting the engines.
If an engine temperature gauge indicates a higher than normal tempera-
ture, the respective cooling system may need to be repaired. If the gauge
needle moves quickly toward a high temperature reading, immediately
shut off the affected engine and have its cooling system inspected and
repaired.
