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.

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.

4 eng

GENERAL INFORMATION

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.

Recommended Practice and Procedures

IMPORTANT: Unplug the trolling motor after each use and when charging the
battery.

• Do not use the main engine battery to power the trolling motor. Use a
dedicated trolling motor battery or battery bank.

• Ensure that the batteries are enclosed and secured within a battery box to
prevent accidental shorting of the battery terminals.

• Route the trolling motor wires on the opposite side of the boat from other
boat wiring.

• Connect boat accessories directly to the main engine battery.

• Do not charge the trolling motor batteries while the trolling motor is in the
deployed (down) position.

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.

• MotorGuide trolling motors are also compatible with AGM (absorbent
glass mat) and Marine Lithium Batteries.

• 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 1.8 m (6 ft) 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.

eng 11

WIRING AND BATTERY INFORMATION

• Use nylock nuts to secure the battery cables to their terminals. Using wing
nuts to secure the battery cables can cause loose connections.

• Do not power any depth sounders or fish finders from the trolling motor
battery. Connecting electronic equipment to the trolling motor batteries
can cause electrical interference. Any depth sounders or fish finders must
be powered from the engine starting or accessory battery.

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.

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. Keep flames away and do not smoke near batteries being charged or
which have been charged recently.

2. Do not disconnect the battery cables while the trolling motor is operating,
because a spark usually occurs at the point where a live circuit is broken.
Always use care to prevent reverse polarization when connecting or
disconnecting cable clamps on chargers. Poor connections are a common
cause of electrical arcs, which cause explosions.

3. Do not reverse the 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.

• The trolling motor should be connected to its own dedicated battery.

• Sensitive electronics, such as depth finders, should be connected to a
separate battery.

• Marine engines should have their own dedicated starting battery.
