3 Safety Information
3.1 Critical Safety Information
Please read all safety information before installing or operating your
electric motor. Severe injury, damage, or even death can occur as a
result of improper usage.
There is a risk of death or severe injury from
electric shock- use caution and do not touch any uninsulated wires
or damaged parts.
• Do not use damaged batteries.
• If wiring is frayed or broken, do not touch it.
• If repair work is needed to the electrical components of your product,
do not attempt to do it yourself.
• If there is any problem with the system, turn off the power
immediately and avoid touching the metal components.
There is a risk of explosion which could result
in death, serious injury, or property damage due to the production
of oxyhydrogen gas from the battery.
• If the battery becomes submerged in water deeper than one meter
for a short period of time, do not attempt to recover the battery, and
refer to the safety instructions provided by the battery manufacturer.
• If the battery has been submerged in shallow water, less than a meter,
for more than 30 minutes, do not attempt to recover the battery, and
refer to the safety instructions provided by the battery manufacturer.
Electromagnetic radiation may cause death or
severe injuries to people with cardiac pacemakers. Those with
pacemakers should not get too close to the motor and should
consult their physician about the proper distance for safety.

7
Batteries can cause severe physical harm or
even death in many different ways. Always read and follow all safety
guidelines and instructions provided by your battery manufacturer.
• Never use third-party chargers for batteries, it could start a re.
• If the battery catches re during use, use water to cool the battery
and prevent re from spreading; however water will not extinguish a
lithium re- if possible, use sand to smother the re.
There is inherent danger in using a boat-
always prepare for the unexpected. A boat which is out of control
can easily result in severe injuries or death by drowning.
• Always check weather predictions and water conditions before a
trip on the water, and also familiarize yourself with a map of the area
you’ll be traversing.
• Depending on the size of your boat, make sure you bring any proper
safety equipment. Paddle(s) and a communication device are a must
for any size of boat, and if appropriate, also bring an anchor and
extra drive.
• Always check your motor and system for any damage and ensure
they are running properly before leaving the dock.
Use caution around rotating components to
avoid possible injury or even death.
• Do not wear loose clothing or jewelry near the motor shaft or
propeller and tie up long hair.
• Never attempt maintenance or cleaning of the motor shaft or
propeller without rst shutting off the system.
• Power down the motor when there are people too near the propeller
or motor shaft.
• Do not use the propeller out of the water.

3.2 Before Use
• This motor should only be operated by an adult who has thorough
understanding and command of the motor, including steering
functions, emergency stop switch, and throttle.
• Always operate your boat and this motor in compliance with local
safety regulations.
• Always carry a paddle on board at all times, especially when using
an electric motor as your primary method of propulsion.
• All passengers should wear approved life jackets at all times.
• Check the status and condition of your motor and battery before
each trip. We recommend starting every trip with a full battery
charge.
• Do not operate the motor outside of the water.
• Do not modify the motor with non-original parts.
3.3 During Use
• Stop the motor immediately if someone is over board.
• Propellers are dangerous- use extra caution when operating the
motor near areas where people may swim. Always be alert and
aware of your surroundings when operating the motor.
• Do not exceed the recommended loading and power limitations of
your boat as suggested by its manufacturer.
Parts may be hot enough to cause burns. Do
not touch the components or battery immediately after use; allow to
cool sufciently before handling the components.
Danger of crushing when tilting the motor-
keep ngers, hands, and all body parts away from mechanical parts
and the area of the motor when tilting the motor.

9
3.4 After Use
• Disconnect the motor from the battery after use.
• Flush the motor carefully with freshwater after each usage,
especially after use in saltwater.
• Do not carry the kayak/boat by lifting with the bracket. This can
cause damage to the boat and potentially to the bracket.
4 Installation
4.1 Install the Motor in the Boat
1. Place the motor on the transom of the boat.
It’s suggested to mount the motor at the centerline
of the boat for better steering experience.

10
2. Tighten the clamp handles to x the motor on the transom of the
boat.
4.2 Trimming the Motor
The motor trimming can be adjusted according to the boat type in
order to get the optimal position relative to the water surface and
better running speed.
Make sure the motor is fully stopped before
adjusting the trim angle.
It’s recommended to try out different trim angles
to have the best performance and highest efciency.

11
1. Make sure the reverse lock is pulled up.
2. Remove the stop ring and pull out the trim pin.

4.4 Connect to the Battery
The motor is adaptable with 36V (three 12V batteries connected in
series) deep cycle marine battery package, 36V LFP lithium battery
(including three 12V LFP lithium batteries connected in series) and 36V
lithium cobalt oxide battery package. Please follow the steps below to
complete the battery connection.
1. Find the battery cables from the motor; there should be a red and
a black cable.
2. Connect the red cable to the positive battery terminal and the
black cable to the negative battery terminal.
3. Make sure the battery cables are connected to the correct terminal.
The motor will not operate if battery cables are installed incorrectly.
4. Tighten the connection of the battery cables to the battery
terminals. Make sure the connection is solid and secure.
Be sure all switches are in the OFF position
before connecting to battery or batteries. Electrical arcing near the
battery could cause an explosion. The battery produces hydrogen
and oxygen gases while charging. This potentially explosive
mixture escapes through the ll vent cell caps and may form an
explosive atmosphere around the battery for several hours after
it has been charged. Electrical arcing or ames can ignite the gas
and cause an explosion, which may shatter the battery and could
cause blindness or other serious injury.
Deppy cycle Batteries contain sulfuric acid,
which can cause severe burns. Avoid contact with skin, eyes and
clothing.
