2. GENERAL INFORMATION
BOATER'S RESPONSIBILITIES
Choose a good weather for your outdoor activity. Personal life-jacket is needed at all
time. 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, shut off the trolling motor before
allowing people to swim or be in the water near your boat.

6
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.
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. 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.
GENERAL PRACTICE
▪Not suggest to 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.
▪After each use, remove sundries from the propeller and rinse the motor by fresh
water.
CIRCUIT PROTECTION
It is recommended to install a manual reset circuit breaker in line with the electric trolling motor positive leads within
1.8m (72 Inches) of the battery(s). Using a circuit breaker could extend up to 2x times of electric motor’s life time.
Please read the spec sheet for your motor’s circuit breaker standard.
During the usage of the electric outboard motor, when the propeller is stuck by the weeds, small stones, fishing lines
or so forth, the circuit breaker will cut off the power automatically to prevent the damage of the electrical parts.

7
When the circuit breaker cuts off the power, disconnect the battery first, then check and clean any obstacles. At last,
press the reset button on the circuit breaker and reconnect the battery, the electric outboard motor is able to continue
the work.
