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.
eng 7
Page 12
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.

IMPORTANT: The bracket must lay flush against the isolators
before being bolted to the deck or the mount will bind, making it
difficult or impossible to unlatch.
7. 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.
Foot Pedal Permanent Installation
NOTE: It is not necessary to permanently mount the foot pedal to
operate the trolling motor.
1. Select an appropriate area on the deck of the boat to install
the foot pedal.

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.
Wire and Cable Routing
• Route the trolling motor wires on the opposite side of the boat
from other boat wiring.
• Accessories should be connected directly to the main engine
battery.

Establishing A Common Ground
Connect the trolling motor and main engine accessories to the
same negative ground terminal. A common ground connection
increases sonar sensitivity and improves the sonar display. Not
establishing a common ground may cause severe corrosion or
electrolysis.

2. Install the propeller onto the motor shaft by engaging the
propeller onto the propeller pin.
3. Install the propeller nut. Tighten securely.
4. Use a MotorGuide propeller wrench or pliers to tighten the
propeller nut another ¼ turn.
Foot Pedal Cable Tension Adjustment
The foot pedal cable tension adjustment is correct when the
exposed number of threads on the tension adjustment shafts are
approximately the same and the amount of deflection of the long
exposed foot pedal cable under a 9.1 kilogram force (20 lbf) pull is
approximately 19 mm (3/4 in.).

To check for proper foot pedal cable tension, apply a
9.1 kilogram force (20 lbf) pull at the center of the long exposed
foot pedal cable. The amount of deflection of the cable should be
approximately 19 mm (3/4 in.). If the deflection is not correct, use
a 13 mm (1/2 in.) wrench to adjust the cable tension nuts to obtain
the proper deflection.
IMPORTANT: Equal adjustments should be made to each cable
tension nut to maintain an equal right and left steering radius with
the foot pedal.
