GENERAL INFORMATION
Boater's Responsibilities
The operator (driver) is responsible for the correct and safe operation of the boat and
safety of its occupants and general public. It is strongly recommended that each
operator (driver) read and understand this entire manual before operating the trolling
motor.
Be sure at least one additional person on board is instructed in the basic operation of
the trolling motor in case the driver is unable to operate the boat.
Protecting People in the Water
WHILE YOU ARE TROLLING
It is very difficult for a person in the water to take quick action to avoid a boat heading
in their direction, even at slow speeds.
Always slow down and exercise extreme caution any time you are boating in an area
where there might be people in the water.
WHILE THE BOAT IS STATIONARY
WARNING
!
A spinning propeller, a moving boat, or any solid device attached to the boat can
cause serious injury or death to swimmers. Stop the trolling motor immediately
whenever anyone in the water is near your boat.
Shut off the trolling motor before allowing people to swim or be in the water near your
boat.
Passenger Safety Message
Whenever the boat is in motion, observe the location of all passengers. A sudden
reduction in boat speed, such as a sharp change of boat direction, could throw them
off the boat.
Safe Boating Suggestions
In order to safely enjoy the waterways, familiarize yourself with local and other
governmental boating regulations and restrictions, and consider the following
suggestions.
eng 3
GENERAL INFORMATION
Use flotation devices. It is the law to have an approved personal flotation device of
suitable size for each person aboard and have it readily accessible.
Do not overload your boat. Most boats are rated and certified for maximum load
(weight) capacities, refer to your boat capacity plate. If in doubt, contact your dealer
or the boat's manufacturer.
Perform safety checks and required maintenance. Follow a regular schedule and
ensure all repairs are made properly.
Never be under the influence of alcohol or drugs while boating (it is the law).
Alcohol or drug use impairs your judgment and greatly reduces your ability to react
quickly.
Passenger boarding. Stop the trolling motor whenever passengers are boarding or
unloading.
Be alert. The operator of the boat is responsible by law to maintain a proper lookout
by sight and hearing. The operator must have an unobstructed view particularly to the
front. No passengers, load, or fishing seats should block the operators view when
operating the boat.
Underwater hazards. Reduce speed and proceed with caution whenever navigating
in shallow water.
Tripping hazards. To avoid a trip hazard, route all cables and wiring neatly and out
of the way.
Report accidents. Boat operators are required by law to file a Boating Accident
Report with their state boating law enforcement agency when their boat is involved in
certain boating accidents. A boating accident must be reported if 1) there is loss of
life or probable loss of life, 2) there is personal injury requiring medical treatment
beyond first aid, 3) there is damage to boats or other property where the damage
value exceeds $500.00 or 4) there is complete loss of the boat. Seek further
assistance from local law enforcement.

WIRING AND BATTERY INFORMATION
Wiring and Battery Information
WARNING
!
An operating or charging battery produces gas that can ignite and explode,
spraying out sulfuric acid, which can cause severe burns. Ventilate the area around
the battery and wear protective equipment when handling or servicing batteries.
WARNING
!
Performing service or maintenance without first disconnecting the battery can
cause product damage, personal injury, or death due to fire, explosion, electrical
shock, or unexpected motor starting. Always disconnect the battery cables from the
battery before maintaining, servicing, installing, or removing motor components.
Standard Practices and Procedures
When installing or removing this trolling motor, follow these guidelines:
• Disconnect the trolling motor from the trolling motor battery.
• Do not use the main engine battery to power the trolling motor.
Battery Recommendations
• Use 12‑volt, deep cycle marine batteries. The number of batteries required
varies according to the model of your trolling motor. Refer to Battery
Connection.
• As a general rule, deep cycle batteries with a higher amp‑hour rating or reserve
capacity rating will provide longer run times and better performance.
• Install a manual reset circuit breaker in line with the trolling motor positive leads
within 180 cm (72 in.) of the batteries. These can be purchased from your local
MotorGuide retailer or from www.motorguide.com.
• Do not extend the included 10‑gauge battery cables more than 1.8 m (6 ft) for a
total of 3 m (10 ft). If longer battery cables are required, MotorGuide offers
accessory 8 mm² (8‑gauge) battery cables.
• Use nylock nuts to secure the battery cables to their terminals. Using wing nuts
to secure the battery cables can cause loose connections.
• Any depth sounders or fish finders must be powered from the engine starting
battery. Connecting electronic equipment to the trolling motor batteries can
cause electrical interference and possible electrolysis.
Battery Precautions
WARNING
!
An operating or charging battery produces gas that can ignite and explode,
spraying out sulfuric acid, which can cause severe burns. Ventilate the area around
the battery and wear protective equipment when handling or servicing batteries.
eng 7
WIRING AND BATTERY INFORMATION
When charging batteries, an explosive gas mixture forms in each cell. Part of this gas
escapes through holes in the vent plugs and may form an explosive atmosphere
around the battery if ventilation is poor. This explosive gas may remain in or around
the battery for several hours after it has been charged. Sparks or flames can ignite
this gas and cause an internal explosion, which may shatter the battery.
The following precautions should be observed to prevent an explosion:
1. Do not smoke near batteries being charged or which have been charged very
recently.
2. Do not break live circuits at terminals of batteries, because a spark usually
occurs at the point where a live circuit is broken. Always be careful when
connecting or disconnecting cable clamps on chargers. Poor connections are a
common cause of electrical arcs which cause explosions.
3. Do not reverse polarity of battery terminal to cable connections.
Wire and Cable Routing
• Route the trolling motor wires on the opposite side of the boat from other boat
wiring.
• Sensitive electronics, such as depth finders, should be connected directly to the
main engine battery. Single battery systems require separate connection
cables.
Battery Connection
!
CAUTION
Disconnecting or connecting the battery cables in the incorrect order can cause
injury from electrical shock or can damage the electrical system. Always disconnect
the negative (‑) battery cable first and connect it last.
12-VOLT BATTERY CONNECTION
1. Install a 50‑amp (good) or 60‑amp (best) manual reset circuit breaker in line
with the trolling motor power cable positive (+) lead and the battery positive (+)
terminal. Connect the trolling motor positive lead to the trolling motor battery
positive (+) terminal.
2. Connect the black trolling motor power cable negative (–) lead to the trolling
motor battery negative (–) terminal.
