PROPULSION
SECTION 5
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 engines. The seacock and strainer for each engine’s
cooling system is located forward of the engine. Refer to Section 9 - 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.
If you intend to operate the boat with only one engine running, you
must first turn off the cooling system seacock for the engine that will
not be running. Failure to do so can flood the non-running engine with
seawater, 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 Section 9
- Thru-Hull Fittings for the location of the engine exhaust outlets. If water is not
being ejected from the outlets, immediately shut off the engines. Determine why
seawater is not being pumped through the system. Have the problem corrected
before restarting the engines.
If the engine temperature gauges show a higher than normal temperature, the
cooling system may need to be repaired. If the needles move quickly toward a
high temperature reading, immediately shut off the engines and have the cooling
system inspected and repaired.
