GENERAL INFORMATION
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.
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
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. 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.
Standard Practices and Procedures
• Do not use the main engine battery to power the trolling motor.
• Disconnect the trolling motor from the battery when charging and
after each use.
• Route the trolling motor wires on the opposite side of the boat from
other miscellaneous boat wiring.
• Connect boat accessories directly to the main engine battery.
Battery Recommendations
• Use a 12 volt, deep cycle marine battery.
• Install a 50 amp manual reset circuit breaker in line with the trolling
motor positive leads within 180 cm (72 in.) of the batteries.
12 eng
Page 17
WIRING AND BATTERY
• Use 13 mm (6 gauge) battery cables if extending the existing wire
beyond the standard battery cable.

Wire and Cable Routing
Route trolling motor wires on the opposite side of the boat from other
miscellaneous boat wiring (bow light wiring, spot light wiring, etc.).
Transducer installation should be installed according to the
manufacturer’s specifications. To avoid interference, cables should be
routed separately from the trolling motor power cables.
IMPORTANT: Do not route the transducer cable down the trolling motor
power cord or foot pedal assembly cable. Route the transducer cable
down the arm of the mount, then into the bow console.
Sensitive electronics, depth finders in particular, should be connected
directly to the main engine battery. If only a one battery system is used,
then connect with separate cables.
eng 13
Page 18
WIRING AND BATTERY
ESTABLISHING A COMMON GROUND
MotorGuide recommends isolating the trolling motor battery/batteries
from the main engine battery.
Electrolysis issues: Using the engine starting battery as a source of
power for any trolling motor may cause electrolysis on metallic parts.
• If you have followed the battery wiring and installation instructions
in this manual and your boat continues to have electrolysis issues,
you will need to separate the trolling motor from any other boat
electronics.
• Remove the engine starting battery from the wiring configuration of
the boat and isolate the power circuit for your trolling motor.
Establish a common ground: Common ground means the ground for
the main engine accessories and your trolling motor are connected to
the same negative ground terminal.
• Not having a common ground can cause severe corrosion or
electrolysis. If left unchecked, damage may be caused to your
trolling motor and boat.
• Establishing a common ground connection will allow increased
sensitivity and improve detail on a sonar display.
RECOMMENDATIONS
Battery type: The recommended battery is a 12 volt deep cycle battery.
Circuit protection: MotorGuide recommends installing a 50 amp
manual reset circuit breaker in line with the trolling motor positive leads
within 180 cm (72 in.) of the batteries. To order a circuit breaker kit,
contact your local service dealer, request kit number MM5870.
Wire size: For optimum performance, MotorGuide recommends the
use of 13 mm (6 gauge) wire if extending the existing wire beyond the
standard battery cable supplied with the product.
Bow plugs: For temporary trolling motor installations, MotorGuide
recommends the use of a quality plug designed for marine applications.

MOUNT INSTALLATION
Transom Mount Installation
TWIST TILLER MODELS
1. Clamp screws: The clamp screws allow for easy motor installation
and removal. Mount your motor on the transom and then tighten
the clamp screws securely.
2. Tilt position pin: This pin allows you to adjust the tilt of the motor.
3. Depth collar adjustment: The depth of the motor can be adjusted
up and down by loosening the depth collar knob. The depth collar
is located on the column directly above the mount. After adjusting
to the position and depth desired, tighten the knob.
4. Steering tension adjustment: To adjust the steering resistance,
simply tighten or loosen the steering friction knob.
Pontoon Mount Installation
1. Carefully select the area on the deck to install the mount. Choose
an area where the mount will provide ample clearance for all of the
motor positions, including the running and stowing positions.
2. Place the mount base on the surface of the boat deck where it is
to be mounted; use the mount base as a template to mark the
location of the holes.
3. Drill mounting holes with a 6.5 mm (0.25 in.) drill bit and clear the
holes of any debris. Countersink the holes (only on fiberglass
boats) and again clear any remaining debris from the holes.
4. Install the four stainless steel mounting bolts through each of the
bracket mounting holes.
5. Install the four stainless steel washers and nuts on the bottom side
of the deck and tighten securely.
6. The trolling motor can now be placed in the mount.
Bow Mount Installation
IMPORTANT: Choose an area on the deck that provides 7.6 cm
(3 in.) clearance from the bow of the boat for all motor positions,
including deployed and stowed positions.

1. Select an appropriate area on the deck of the boat to install the
mount. Ensure the forward mounting screws will not penetrate the
hull.
Mount on deck with a 7.6 cm (3 in.) clearance
2. Using a Phillips head screwdriver and the decket screws provided
in the hardware bag, secure the decket to the mount base. (The
decket for heavy duty spring mounts can be installed last.)
3. Use the bow mount base as a template to mark the location of the
front mounting holes in the plastic decket and the rear mounting
holes on the mount base.
4. Drill the mounting holes with a 6.5 mm (0.25 in.) diameter drill bit.
Remove any debris.
eng 19
Page 24
MOUNT INSTALLATION

5. If using rubber mounting isolators, drill each mounting hole with a
13 mm (0.5 in.) diameter drill bit.
NOTE: A rubber spacer or washer should be used between the base
of the mount and the boat mounting surface when the rubber isolators
are not used.
6. Insert the rubber mounting isolators into the drilled holes. Position
the wider side of the isolator toward the outside of the mount
bracket.
7. Place the mount bracket on the isolators and align the holes. Install
the two longer screws into the front holes and the two shorter
screws into the rear holes. Tighten all of the mounting screws with
a Phillips screwdriver. Do not tighten the mounting screws with an
electric screwdriver.
NOTE: It is important that the bracket lies even against the isolators
before bolting it to the deck. If the mount is not even, it will bind as it is
bolted down making it difficult or impossible to unlatch. Once installed,
the latch pins should snap firmly into place and release easily with a
quick snap of the wrist and a light pull of the rope handle.
8. When the bracket is installed, it should fasten securely and evenly
with the latch pins and release with a light, quick, pull of the rope
handle.

Constant/Momentary/High‑Bypass
Momentary switch: The momentary switch is located on the top right
side of the foot pedal. The momentary switch works in conjunction with
the three‑position switch when it is in momentary or high‑bypass
position.
Three-position switch: This three‑position switch provides three
options for operating the motor: constant on, momentary, and
high‑bypass.
• Constant on: This allows the motor to run continuously at the
speed selected by the speed control knob without the use of the
momentary switch.
• Momentary: This allows the motor to activate with the momentary
switch at the speed selected by the speed control knob.

MAINTENANCE
Refer to the Maintenance—Inspection and Maintenance Schedule
section and complete the appropriate care instructions to prepare your
trolling motor for storage. Store the trolling motor in a dry location where
it will not be affected by temperatures below ‑29 °C (‑20 °F).
IMPORTANT: Trolling motors stored in temperatures below 0 °C
(32 °F) should be operated slowly for a minimum of 15 minutes before
going above 30% operation.
Battery Inspection
The battery should be inspected at periodic intervals to ensure proper
trolling motor operation.
IMPORTANT: Read the safety and maintenance instructions which
accompany your battery.
1. Ensure that the battery is secured to the vessel.
2. Ensure that the battery cable terminals are clean, tight, and
correctly installed. For installation instructions, refer to Wiring and
Battery.
3. Ensure that the battery is equipped with a battery box to prevent
accidental shorting of the battery terminals.
Propeller Replacement
WARNING
!
Performing service or maintenance without first disconnecting the
battery can cause product damage, personal injury, or death due to

Great White Saltwater Models Only
Corrosion on the metal components of the trolling motor occurs when
two or more metals that are dissimilar are brought into electrical contact
underwater.
The use of a sacrificial anode causes all of the other metals on the
trolling motor to become the cathodes. The anode will corrode and the
trolling motor will not.
Maintenance: If excessive corrosion occurs, replace the anode.
