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
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. While in boat trolling, 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.
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, or a sharp
change of boat direction, could throw them off the boat. In order to safely enjoy in the waterway, familiarize yourself
with local and other governmental boating regulations and restrictions, and consider the following suggestions.
Use flotation device - It is required by 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 a maximum load (weight) capacities. Refer
to your boat capacity plate. If in doubt, contact the dealer or the boat's manufacturer.
Perform safety check and required maintenance. Follow a regular schedule and ensure all repairs are made
properly.

5
It is required by law that NEVER be under the influence of alcohol or drugs while boating. 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 highly recommended 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 hazard - Reduce speed and proceed with caution whenever navigating in shallow water.
Tripping hazard - To avoid a trip hazard, route all cables and wiring neatly and out of the way.
Report accident - Boat operators are required by law to file a boating accident. Report with their local boating
law enforcement agency when their boat is involved in certain boating accident, such as 1) there is loss of
life or probable loss of life, 2) there is personal injury requiring medical treatment beyond first aid, or 3) there
is a complete loss of the boat. Seek further assistance from local law enforcement for details.
GENERAL PRACTICE
Not suggested 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 specification for your motor’s circuit breaker standard.
When the propeller is stuck by the weeds, small stones, fishing lines or so forth during the usage of the electric
outboard motor, the circuit breaker cuts off the power automatically to prevent the damage of the electrical parts.
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
to work.

Unplug the trolling motor after each use, and when charging the battery.
An operating or charging battery produces gas that can ignite and explode,
spraying out sulfuric acid can cause severe burns. Ventilate the area around the
battery and wear protective equipment when handling or servicing batteries.
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.
Do not allow children to operate the electric outboard motor.
Do not modify the unit in any way or add accessories not intended for this product.
Do not submerse the motor upper-unit controller box. If the unit is accidentally
submersed, disconnect battery right away. The motor needs a full service within 24
hours if suffered such a water damage.
Always disconnect power of the motor when replacing propeller or transport.
To prevent accidental damage of the fiberglass shaft, do not over tighten the
mounting bracket.
Only use this product between the temperatures of -20C to +45C (-4F to +113F).

WIRING AND BATTERY
Route the trolling motor wires on the
opposite side of the boat from other
boat wiring. Sensitive electronics, such
as depth finders, should be connected
directly to the main engine battery.
Single battery system requires
separate connection cables.
BATTERY
12V Model: 1x 12V 105AH (Group 27) deep cycle marine battery suggested
24V Model: 2x 12V 105AH (Group 27) deep cycle marine battery suggested
To extend the running time, use a larger capacity battery or an additional battery. As a general rule, deep cycle
batteries with a higher Amp‑hour rating or reserve capacity rating provides a longer run time and better performance.
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 starting engine or accessory battery.
For better overall performance, it is recommended to fully charge the batteries after each use. Disconnect the
batteries from the motor before charging. Frequently charge the batteries to capacity to keep them in good condition.
