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 stern of the boat and tighten both mounting bolts
securely while taking care not to over-tighten. (A)
To adjust the angle of the motor after attachment, hold the motor head with
one hand and depress the positioning pin at the top of the mounting bracket
with your other hand. Press and hold the positioning pin until the desired
angle has been reached, next release the pin and ensure the mechanism locks
securely. (B)
Please note the angle adjustment option is only available on the ASP T-24 Motor
with the metal bracket. The ASP-T18 Motor with the Nylon Bracket does not tilt.
TIGHTEN BOTH BOLTS SECURELY
DEPRESS THE POSITIONING PIN

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 12v deep cycle
battery. Your Watersnake motor is supplied
as standard with alligator clip 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 highly
recommended. Attach to the red power cable
to protect the circuit boards of the motor. As
shown on diagram 1. This is a connection that
joins the motor battery cable to the battery and
shuts the motor off if the connection over heats.
See Watersnake circuit breaker on page 20.
Available as a seperate purchase.
We recommend using a deep cycle battery for
optimum performance.

DEEP CYCLE BATTERIES
A 12v deep cycle battery is required for normal operation and continued use of
your Watersnake motor. 12v deep cycle batteries are constructed using thicker
plates and a denser active material. They are built to withstand repeated
charge and recharge cycles. Deep cycle 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.
BATTERY CHARGING
• Do not attempt to charge your battery while your Watersnake is still
connected to the battery.
• Do not connect your Watersnake motor to a battery that is connected to your
main motor’s charging system (alternator).
• It’s important to note that a fully charged 12v deep cycle battery will actually
provide more than 12v (refer to your battery supplier for more information)
and at 12v or less your Watersnake motor may not operate normally.
• Do not connect your Watersnake motor directly to solar panels.
Note that 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.

VOLTAGE DROP
The included battery cable should not be extended by more than 1m, due to
the wire gauge. This avoids damaging voltage drop. To get a cable longer than
this, replace the existing cable as well so the entire length is the correct wire
gauge for the new length. This modification should only be performed by a
marine technician or auto electrician. Only use twin-sheathed tinned cable.

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 of
the depth collar securely.
STEERING
To adjust steering counter-force, simply loosen or tighten the counterforce
bolt. The ideal setting is one where the counterforce bolt is just tight enough
so that the boat will steer in the direction you are aiming without need for
continual correction.

HEAD UNIT & SPEED CONTROL
The Head units controls are easy to use. There is a switch for forward and
reverse ( I o R ) and a switch for low (-) or high speeds (=).
The handle of the motor head is stowable and extends with the pull of a
button. This makes the motor more compact and easier to store away
when not in use.
Pull button to
extend handle.

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 transom mount bracket.
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)
• 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. 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. 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 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 11.
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 boat and stow safely in either your vehicle or boat.

www.watersnake.com.au 13
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.
