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.
eng 5
GENERAL INFORMATION
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.
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.
6 eng
GENERAL INFORMATION
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
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.
