The flow of fresh water into and out of the engine's cooling system is regulated by the
thermostat.
19:03 BOTH FRESH AND SEA WATER SYSTEMS: Water is circulated through the engine and
the heat exchanged by a water pump with neoprene rubber impellers. The nature of these
impellers requires that they never be run dry. A spare impeller and impeller cover gasket
should always be kept on board. Refer to engine owner's manual for type, location and
replacement procedures.
Routinely check the exhaust port at the transom to see if water is being expelled and
insure that cooling water is being circulated through the system. It is especially
important to check after an impeller has been changed or other engine work has been done.
19:00 ENGINE COOLING AND EXHAUST SYSTEMS (Cont'd)
19:04 ENGINE BACKFIRE: The exhaust system as a unit is constructed of parts designed
to withstand internal pressure several times greater than that which is expected in a
normally operating wet exhaust system. However, engine backfires are capable of very
high instantaneous pressures which may exceed the system's capacity. Therefore, if a
backfire occurs, the entire exhaust system should be examined thoroughly for any resultant
damage.
19:05 HOT WATER HEATERS: (Option) Hot water heaters utilizing the engine's hot water
as a source of heat, tap into the cooling system as the water leaves the engine at its
hottest point. It then circulates through the water heater where a heat exchanger heats
the domestic hot water. (Refer to I­30)
19:06 WINTERIZING: The engine and exhaust system require special attention when
preparing for winter storage. (Refer to Section 30:00 for complete winterizing details)
20:00 ELECTRICAL SYSTEM 12 VOLT DC
Wiring for the 12 volt system has been run in accordance with industry standards and
quality wire and connectors have been used throughout. A salt air environment and
continual boat vibrations require that wires and terminals be checked routinely for
corrosion or wear.
20:01 BATTERY SWITCH: A master battery switch located on the galley face completely
controls the flow of power out of the batteries. Systems with two batteries have switches
for selecting each battery separately or both batteries together. Systems with one
battery have switches with on or off position.
CAUTION: DO NOT SHUT OFF THE BATTERY SWITCH WHILE THE ENGINE IS RUNNING OR SERIOUS
ALTERNATOR DAMAGE WILL RESULT.
20:02 BATTERIES: Batteries are located under the quarter berth in durable and
corrosion resistant cases.
It is important to keep batteries fully charged at all times. Low batteries may effect
the function of the radio, depth sounder and other electronics.
Charge batteries separately when charging with the engine's alternator. Do not attempt to
charge dead or extremely low batteries with the alternator. The batteries should be
charged out of the boat. Batteries should also be removed for winter storage.
Inspect monthly and keep battery cable terminals clean at all times. A thorough cleaning
should be done yearly using a stiff brush and a solution of baking soda and water. After
cleaning, apply a light layer of petroleum jelly to cable terminals to retard corrosion.
Check fluid level in each battery cell once each month. If low, add water to about 1/2"
above the top of the plates. Do not overfill, and never add anything to fluid except
clean, fresh water. Use distilled water if available.
