BATTERY AND POWER
BATTERY TYPE
USE A  VOLT DEEP CYCLE OR A V LIFEPO BATTERY
12V DEEP CYCLE BATTERY
Deep-cycle batteries deliver sustained power with low current draw over
extended periods. They can be drained to low levels without developing a
“memory” and can be fully recharged hundreds of times over their working lives.
Do not use a standard car, truck or marine batteries (called a cranking battery).
They are designed to provide a pulse of “cranking power” over a short period,
can develop a “memory” preventing complete recharge and can produce current
surges that may damage sensitive electronic components on your Watersnake.
LITHIUM BATTERIES
BEST PRACTICES
INSTALLING AND CONNECTING YOUR MOTOR
1. Your Watersnake motor is designed to be powered by a 12v deep cycle or
LifePO4 battery that should output no more than 14.5v. If the voltage input
to your Watersnake motor exceeds 14.5v it may damage the sensitive
electronics and void your warranty. A dedicated battery system is preferable.
Do not connect other items like fish finders or lighting to the trolling motor
battery.If you are unsure about the voltage output of your battery, contact
your battery supplier or consult a marine auto electrician.
2. This Watersnake motor is compatible with a battery system that is being
charged by an alternator or solar system, so long as the voltage input to the
Watersnake motor does not exceed 14.5v whilst the battery is being charged.
3. Route the wiring from the battery to the trolling motor on an alternate route
or path to other wiring on the kayak. If possible, it is preferable the wire is
fitted to the opposite side of the kayak to other wiring.
4. If you have to extend the wiring to connect the motor please review
the extending battery leads section of the manual (page 9) so you fully
understand this process.
5. This trolling motor requires a circuit breaker or inline fuse to protect the
motor. See page 8 for more information.
CAUTION: Please read the following information before you
connect your electric motor to your baery.
TERNARY LITHIUM BATTERY WARNING
Ternary Lithium batteries must not be used with this Watersnake motor
as their voltage output is too high.

www.watersnake.com.au 7
INLINE FUSE OR CIRCUIT
BREAKER
An inline fuse or circuit breaker is required when connecting your Watersnake
Asp motor to the battery. This is a connection that joins the motor battery
cable to the battery and protects the motor by shutting off power in the event
of an overload or short circuit.

12V LIFEPO4 LITHIUM BATTERY
Lithium Iron Phosphate (LiFePO4) is the safest lithium battery type. We
recommend doing your research on a LiFePO4 battery before purchasing to
make sure you are purchasing from a reputable company and the battery has a
maximum voltage output under 14.5V. There are many cheap lithium batteries
on the market that can be harmful to your Watersnake motor.

EXTENDING BATTERY LEADS
The longer your battery cable needs to be, the thicker it needs to be to avoid
damaging voltage drop. The supplied cable has the correct wire gauge
(thickness) for its length. But if you need to extend the length by more than
30%, you will need to replace the existing cable completely with a new longer
thicker cable. This means the entire cable will be the correct wire gauge for
the new length. See below to find the correct wire gauge for your motor thrust
and required cable length. Only use twin-sheathed tinned cable.
Note: The above table is intended as a guide only. Your local electrical supplier will
be able to advise in greater detail based on your particular set up and requirements.

BATTERY CHARGING
Charging a battery while it is powering the motor will increase the voltage
delivered to the motor. This motor can be powered by a charging battery (e.g.
charging with an alternator or solar panels) as long as the voltage it receives
does not exceed 14.5 volts. Exceeding 14.5 volts will potentially damage
electrical components in the motor and is not covered by warranty.
When you are off the water and are charging your battery at home for long
periods of time via a 240v or 110v AC charger we recommend you disconnect
the motor from the battery.
AVOID USING STOREBOUGHT BATTERY
BOXES WITH BUILTIN CIRCUITRY
Battery Boxes use low quality electrical components that cannot handle the
high current loads that trolling motors draw. We recommend connecting your
Watersnake motor directly to a deep cycle or LiFePO4 battery using the provided
battery leads.

All Watersnake wiring connections should conform to best marine standards.
Soldered, sealed and heat-shrink protected. If you doubt your ability to
produce quality waterproof connections or lack the equipment, consult a
marine technician or auto electrician.
• Your Watersnake comes factory-fitted with a standard length of twin flex
wiring with alligator clips to attach to the battery.
• Before connecting the motor’s cables to the battery terminals, ensure all
switches are in the OFF position and stand clear of the propeller.
• Connect the red cable to the positive (+) terminal and the black cable to the
negative (-) terminal, making sure the terminals are clean before doing so.
A clean connection will minimise power wastage and give you maximum
power from the battery.
• The voltage input must be 14.5V or lower. Voltage input above 14.5V will
damage the motor and void the warranty.
• If you intend to charge your battery via an alternator or solar panel, it is
important that the battery voltage output does not exceed 14.5v. If you are
unsure of the voltage your battery will output, consult a marine technician
or auto electrician.

RECOMMENDATIONS
WHEN USING YOUR WATERSNAKE MOTOR
IN THE WATER
Upon connecting your battery to your motor, and before setting off in your
kayak, make sure that your trolling motor is mounted correctly and stowed
securely. Of course once you engage your Watersnake motor for use make
sure that it is in the right place, not too low or too high. Once you are in
deep water, you should make sure that you gradually increase the speed
of your trolling motor, do not accelerate it up to full speed right away. It is
recommended not to run your trolling motor out of water for long periods of
time.
AFTER EVERY USE
• Disconnect the motor from the battery.
• Recharge the battery as soon as possible.
• DO NOT PRESSURE WASH, EVEN AFTER FRESHWATER USE.
• Wipe your motor down with a wet rag. Concentrate on areas where salt, dirt
and weed fragments are likely to lodge – propeller, motor housing, alloy
shaft, depth collar and exposed parts of the mount assembly.
• Wipe these areas with a cloth soaked in warm soapy water and allow to dry.
• Apply a light coating of a non-staining silicone, petroleum-based or lanolin
spray to protect and lubricate exposed parts. Wipe over with a soft, dry
cloth.
• Store your Watersnake motor DISCONNECTED from its battery.
• If the kayak is stored outdoors, remove the Watersnake motor and store
securely indoors in a cool, dry place.
• If the Watersnake motor is permanently mounted to the kayak outdoors,
consider protecting it from harsh sunlight and the elements with a tarpaulin
or other cover.
TRANSPORT
WHEN TRANSPORTING YOUR KAYAK IT IS RECOMMENDED
THAT YOU REMOVE THE MOTOR FROM THE KAYAK.
To remove the motor from your kayak simply loosen the bolts holding the jack
beam in place and slide it out. Re tighten the bolts on the bracket
so you do not loose them during transport. When you arrive at you destination
re-attach the motor to your kayak.

TROUBLESHOOTING
QUICK REFERENCE GUIDE
A significant number of issues can be caused by a disruption of power supplied
to your Watersnake motor. Careful inspection of your 12v deep cycle battery,
wiring and fuse / circuit breaker set up should be completed before assuming
that there is a fault with your motor.
NO POWER / REDUCED POWER
• Check that battery connection has not been reversed (reversed polarity).
• Check that your 12v deep cycle or LiFePO4 battery is fully charged (+ 12v).
• Check terminals / connections are secure and not loose.
• Check terminals / connections / fuse or circuit breaker for any signs of
damage, corrosion or build up of debris.
• If the battery cable has been extended but not replaced, you may be
experiencing damaging voltage drop. Check the table on page 8 to see if you
have the correct gauge wire for the length of cable extension.
• With the battery disconnected remove propeller and check for any build up
of fishing line / weed or any other debris.
• With the battery disconnected check that propeller pin (shear pin) is in
place.
• Armature or magnet cracked or dislodged – grinding noise will come from
motor (Contact the Watersnake distributor in your region.)
NOISE OR VIBRATION COMING FROM MOTOR
• With the battery disconnected check that propeller is securely tightened and
shear pin is in place. Remove propeller and check for any build-up of fishing
line / weed or any other debris. Rotate the propeller 180º and then recheck
for vibration.
• Check that your 12v deep cycle or LiFePO4 battery is fully charged (+ 12v).
