WATERSNAKE ELECTRIC MOTORS
Congratulations and welcome to a world of silent motoring.
Powerful yet silent, the Watersnake electric motors are built to suit all angling
conditions. High quality materials, superior design and precision engineering
make these motors longwearing and reliable.
Please read manual completely before starting installation.
ATTACHING THE MOTOR TO YOUR BOAT
Attach the motor to the bow of the boat, taking care to ensure the motor is
on the centreline of the boat and forward enough to avoid the shaft making
contact with the boats gunwale rubber. With the motor in position, mark the
holes for drilling, ensuring as you do that the bow area below the mounting
location is clear and accessible.
Mount the plate to the bow using stainless steel bolts, nuts and washers.
It is important when doing this work that the boat is level and the motor is
mounted level.
Remove covers to expose
Mounting Plate.
After the Motor is Mounted
replace covers.
Watersnake Distribution Pty Ltd accepts no
liability for injury or damage caused while drilling/
mounting this motor. Please wear appropriate
protective clothing and eyewear/ face shield.)
If you do not want your motor attached to the bow
of your boat at all times it is recommended that you
purshase aJarvis Marine quick release bracket.
OPTIONAL QUICK RELEASE BRACKET (Sold Seperately)
You can also mount your motor using a Jarvis Marine Quick release bracket,
which allows you to easily attach or remove the motor to your boat, for
transport and storage. Full mounting instructions are included with the
brackets.

ELECTRICAL CONNECTIONS
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.
Please Note: for best performance please keep
battery terminals and connections clean.
There are a number of different methods of
connecting battery leads to your 12 v deep
cycle battery. Your Watersnake motor is
supplied as standard with ring type terminal
connectors although this can be changed to
suit your particular set up. If fitting different
terminal connectors ensure that connections
are soldered and sealed appropriately. It is
recommended to use heat shrink to seal any
exposed joins in wiring or connectors. Any
non-standard terminal connections must be
capable of handling a minimum of 50 amps.
Anderson plugs are a popular choice amongst
many Watersnake motor owners and are readily
available.
A Watersnake circuit breaker is supplied and
attached to the red power cable to protect the
circuit boards of the motor. This is a connection
that joins the motor battery cable to the battery
and shuts the motor off if the connection over
heats. As shown on diagram (1)
We recommend using a deep cycle marine
battery for
optimum performance.

DEPLOYMENT
Pressing on the quick locking and release lever (refer to diagram on page 4)
at the same time as pushing the shaft forward will allow the motor to release
from the cradle. NOTE – Your Watersnake motor is not designed to release
from the cradle by pressing on the lever alone. Applying excessive pressure to
the release lever can lead to deployment difficulties.
DEPTH ADJUSTMENT
Hold the motor shaft with one hand, loosen the depth collar adjustment screw
and set the motor to the desired depth. Then retighten the adjusting screw on
the depth collar securely.
STOWING
When your Watersnake motor is not in use always stow and store it properly.
Press the quick locking and release lever and raise the motor, pulling towards
the stern of your boat until it is secure on the locking cradles and locked into
the horizontal (stowed) position. A final pull on the shaft of the motor may be
necessary to ensure it has locked into place on the cradle.
(refer to diagram on page 4)
DEEP CYCLE BATTERIES
A 12 v deep cycle marine battery is required for normal operation and
continued use of your Watersnake motor. 12 v deep cycle marine batteries are
constructed using thicker plates and a denser active material. They are built to
withstand repeated charge and recharge cycles. Deep cycle marine batteries
are specifically designed to deliver sustained power with low current draw over
extended periods of time. Car / Truck / Motorcyle batteries are not designed
in the same way and are more useful for providing high bursts of power for
short periods. Use of car / truck / motorcycle batteries can cause damage to
electronic components within your Watersnake motor.

REMOTE CONTROL HAND UNIT
The remote control hand unit must be synced with your motor (refer below).
The remote control hand unit requires “line of sight” communication with the
remote receiver in the head of your Watersnake motor. Normal operation
may be impaired if the remote control hand unit is operated from behind a
bulkhead or other structure such as a centre console that impedes line of
sight communication.
The remote control hand unit is battery powered. The battery in the unit may
need to be replaced after 12 months or sooner if used regularly. The battery
used is a commonly available CR2032 and can be changed by removing the 4
phillips head screws from the back of the unit. NOTE – Your remote control
hand unit must be re-synced with your Watersnake motor after changing the
battery.

MAINTENANCE
Your Watersnake Electric Motor should provide many seasons of dependable
service. However, like any tool, electric motors must be cared for.
After each day of fishing, the motor should be cleaned thoroughly. A light
rinse with fresh water (do not direct a high pressure stream of water at the
motor) and wash with warm soapy water to remove any remaining salt / debris
particles should be completed. It is good practice to pay particular attention
to areas that are likely to hold salt / debris particles such as the shaft of the
motor and the area surrounding the turning motor housing where the depth
collar sits when the motor is deployed.
NOTE – The above cleaning routine should also be followed even if the motor
has been used in fresh water. Dust / dirt can still build up in fresh water
environments.
Dry excess moisture from the motor and sparingly lubricate all friction points
– a pressurized spray lubricant is ideal. It is important to keep the shaft of
your motor as smooth as possible to avoid deployment issues. A light coat of
wax or a coating with a spray lubricant should be applied to the shaft a couple
of times a year.
Periodical general maintenance (once or twice a year depending on use)
• Remove side covers from the mounting assembly and clean any build up
of dirt / debris that may be present on the inside of the bow mount assembly
(mounting bracket). Applying harsh chemical cleaners is not recommended
– warm soapy water should be sufficient.
• While side covers from the mounting assembly are removed apply marine
grade grease to the quick lock and release mechanism. Do not use grease
that may contain lead particles.
• Check for any loose screws / bolts / fittings and tighten as required.
• Check wiring / terminals for any sign of corrosion or build up of debris
• Check fuse or circuit breaker for any sign of corrosion or build up of debris

RECOMMENDATIONS WHEN USING YOUR
WATERSNAKE MOTOR IN THE WATER
Upon connecting your battery to your motor, and before setting off in your
boat, make sure that your trolling motor is mounted correctly and stowed
securely in the mounting bracket. 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 flatten it up to full speed right away.
For example, if you have a 5 speed trolling motor, don’t click through all of the
other speeds really fast to get to 5, slowly go up to 1 speed, 2 speed, and so on.
It is recommended not to run your trolling motor out of water for long periods
of time.
RECOMMENDATIONS WHEN YOUR
WATERSNAKE MOTOR IS OUT OF THE WATER
After washing down your Watersnake motor at the end of a session, you may
need to charge your 12v deep cycle marine battery. Before charging your
battery, ensure that your Watersnake motor is disconnected from the battery.
DO NOT leave your motor connected whilst charging your battery.
If your boat is not stored under cover, it is recommended to remove your
Watersnake motor and store separately under cover, out of direct sunlight and
away from wet or damp areas. If you are not able to remove your Watersnake
from the boat, we recommend covering your Watersnake with a weatherproof
cover to protect the electronics.
The off-season provides a good opportunity to complete some maintenance as
outlined on page 13
When towing your boat long distances and especially if driving over rough /
unsealed roads, we strongly recommend that you remove your Watersnake
motor from your bow and stow safely in either your vehicle or boat.

www.watersnake.com.au 15
SHORT-TERM STORAGE OF YOUR WATERSNAKE MOTOR
If you are going to be gone for a short break or there is rain forecast and the motor is to remain
on the boat, we recommend covering the motor to protect the electronics. Even better, make sure
that you have a safe non-damp area that your trolling motor can stay in room temperature.
LONG-TERM STORAGE OF YOUR WATERSNAKE MOTOR
If you are not going to use your motor in the off-season, put your motor in a safe place where no
water or extreme cold or hot temperatures can get in. We suggest making a place under-cover
away from moisture, this should protect the electronics such as the circuit board and speed
control unit.
