6.8 Engine Control
Systems Circuit Protection
Main Circuit Breakers
Mercury engines with electronic steering and con-
trol systems are equipped with heavy duty circuit
breakers or fuses for each steering pump and the
controls that protect those components from an
overload. Other heavy duty circuit breakers or
fuses protect the charging circuits for each engine.
Circuit protection will vary with each engine instal-
lation as controls and steering systems may be
different. Refer to the engine and steering system
owner’s manuals for information on circuit protec-
tion and amperage requirements for the engines
and control systems on your boat.
6.9 AC Battery Charging System
General
A 120 volt AC battery charging system is an avail-
able option.
The battery charging system is fed 120 volt AC
current by a power cable connected to a shore
side outlet and the shore power inlet located in the
stern above the swim platform. It is wired totally
separate from the 12 volt DC system and auto-
matically charges the batteries when connected.
Notice:
The power cord used for the battery charger
is not equipped with lock rings on the shore
side or boat connector plugs. The battery
charger has integrated reverse polarity pro-
tection and the circuit is not equipped with
a reverse polarity light.
DANGER
TO REDUCE THE POSSIBILITY OF AN ELECTRICAL
SHOCK, IT IS IMPORTANT THAT THE AC GROUND SYSTEM
IS FUNCTIONING PROPERLY AND THAT A PROPER
CONNECTION EXISTS BETWEEN THE SHORE POWER
CORD AND THE SHORE POWER INLET AND THE OUTLET
GROUND CIRCUITS. IF THERE IS ANY DOUBT ABOUT THE
INTEGRITY OF THE GROUND CIRCUIT, A QUALIFIED MARINE
ELECTRICIAN SHOULD BE CONTACTED IMMEDIATELY
AND THE SHORE POWER DISCONNECTED UNTIL THE
NECESSARY REPAIRS ARE COMPLETED.
ELECTRICAL SHOCKS FROM 120 VOLT CIRCUITS CAN
CAUSE SEVERE INJURY OR DEATH. TO REDUCE THE
RISK OF ELECTRICAL SHOCK IN WET WEATHER, AVOID
MAKING CONTACT WITH THE SHORE CABLE OR MAKING
A CONNECTION TO A LIVE SHORE OUTLET. NEVER SPRAY
WATER ON ELECTRICAL CABLES WHILE WASHING DOWN
DECKS.
Recommended Procedure For Making a
Shore Connection
If the dockside outlet includes a circuit breaker,
turn it to the OFF position. To avoid strain on
the cable make sure it has more slack than the
mooring lines. Dress the cable so that it cannot
be damaged by chafing between the boat and
the dock. Make sure the cable does not come in
contact with the water. Then connect the cable in
the plug inlet making sure the connection plug
includes a three-prong plug with a ground wire.
Turn the dockside circuit breaker on and check
that the battery charger is operating properly. If
the battery charger is not working, turn off the
shore breaker and remove the cable. Contact your
dealer or a qualified electrician to find and correct
the problem.
WARNING
DO NOT ATTEMPT TO CORRECT THE WIRING YOURSELF.
ELECTRIC SHOCK CAN CAUSE SEVERE INJURY OR EVEN
DEATH. ALWAYS HAVE A QUALIFIED ELECTRICIAN CHECK
WIRING.
KEEP CHILDREN AWAY FROM ANY ELECTRICAL CABLES
OR EQUIPMENT.
WARNING
UNDETECTED FAULTS IN THE AC BATTERY CHARGING
SYSTEM COULD CAUSE THE WATER AROUND THE BOAT
TO BECOME ENERGIZED. THIS COULD CAUSE A SEVERE
SHOCK OR EVEN DEATH TO SOMEONE IN THE WATER NEAR
THE BOAT. NEVER SWIM OR ALLOW SWIMMING AROUND
THE BOAT WHEN THE BATTERY CHARGING SYSTEM IS
ACTIVATED BY THE SHORE POWER CONNECTION.
Disconnecting procedure for shore power
connection
Turn the circuit breaker on the dockside outlet to
the OFF position. Disconnect the cable from the
dockside outlet and replace the outlet caps. Dis-
connect the cable from the boat and replace the
inlet cap. Store cable.
Battery Charger
The battery charger is mounted in the aft storage
compartment. The charger automatically charges
and maintains the engine and house batteries
simultaneously when activated. It is equipped
with led lights to indicate the state of charge for
each battery.
