2 Preparations
2.1 Selecting the Battery
Lithium-based and lead-acid batteries can be used to supply power for
NAVY 3.0. Considering the high performance in energy density and
discharge ability, lithium-based batteries are more preferable. To ensure that
NAVY 3.0 can work at its full power continually, the batteries are required
to possess over 62.5A of continuous discharge current. To ensure longer
operating duration, the battery capacity is recommended to be 3000Wh or
above.
The rated continuous discharge current is affected by the battery type and
quantity of parallel batteries. To use lead-acid batteries, conventional leadacid or AGM or GEL batteries are acceptable, while starter batteries are not
recommended. Traction batteries or deep cycle batteries are more preferable
as they give power over sustained period of time. Besides, the deep cycle
marine batteries are also capable.
Battery capacity is a major factor that affects trip duration and distance.
For instance, a battery with 48V of rated voltage completely discharges at
a continuous current of 62.5A in 1 hour, so its rated capacity is 3000Wh
(62.5Ah*48V=3000Wh), we also can say its rated capacity is 62.5Ah. The
maximum power of NAVY 3.0 is 3KW which means the system can be
running at full power for about 1 hour when using this battery. You can select
a battery with proper capacity based on your requirements for travelling time
and distance. Note that the operating time and distance are also affected
by the input power of the outboard plus the external environment and
temperature. In addition, the type and tonnage of boats also play important
roles.
Users can choose NAVY Battery designed by ePropulsion for NAVY
outboard motors, which is a type of Lithium-ion battery with 3000Wh
capacity. When using with NAVY 3.0, one or more sets of NAVY Batteries
are required. When more than one NAVY Batteries are used in parallel,
communication cables should be used to connect NAVY batteries and NAVY
3.0 outboard motor for internal information exchange.
Users can connect four 12V batteries in series to make a 48V battery set
and use it to supply power for NAVY 3.0. Users can also enlarge the battery
capacity by parallel conguration.
Page 16
14
When using NAVY Batteries, the batteries will work well once being
correctly connected. When using non-ePropulsion batteries, before
starting the outboard, users should configure the batteries via the
Remote Control for the rst time use, otherwise the batteries may not
work properly.
Only use the same batteries (same model, same capacity, same age
and same manufacturer) in series or in parallel conguration. Variations
in the batteries will cause damage to them.
2.2 Mounting the Propeller
Figure 2-1 displays how to mount a propeller correctly.
Step3: Attach the propeller.
Step4: Attach the Φ12 washer.
Step5: Tighten the nut with 19mm (3/4 inch)
socket wrench.
Step6: Attach the Anode.
Step1: Attach the Φ16 washer.
Step8: Screw and tighten the nut
with M6 hexagon wrench.
Step2: Fix the pin to the hole of shaft.
Step7: Attach the Φ6 washer.
Figure 2-1
Page 17

3 Mounting the Outboard Motor
Select an outboard with proper shaft length according to the transom height
of your boat. The top of the propeller should be 100mm to 150mm below the
bottom of the boat.
The outboard should be mounted on the centerline of your boat. If the boat
shape is asymmetric, please consult your dealer for proper solution.
3.1 Position of Mounting
The mounting height of the outboard affects the running speed seriously.
When the mounting height is too high, cavitation may occur, which may
lead to speed slowdown, energy waste, and propeller damage. When the
mounting height is too low, the water resistance will increase reduction in
both travelling speed and power efciency.
In general, the optimal mounting height is affected by the specic conditions
of a boat. In order to get the optimal mounting height, it’s suggested to test
running by mounting the outboard at different heights. Please consult your
dealer for more information.

Ensure the outboard is firmly fixed as loosened clamp screws may
cause the outboard to fall into water or get damaged. Check the screws
or clamps every time before use since they may be loosened because
of mechanical vibrations.
A cable is recommended to be used to avoid complete loss of your
outboard in case it falls off the transom. Use the cable to connect your
outboard and a secure mounting point on the boat.

3.3 Mounting the Steering System (R)
When using the Remote Control, please prepare a steering wheel (not
supplied with NAVY 3.0) and mount it on the corresponding position to
control the direction.
Step2: Mount the Link arm with
two M8 nuts.
Step3: Fasten the steering wheel
shaft on the steering tube
with thread.
Step1: Insert the steering wheel
shaft into the steering tube.

3.4 Mounting the Tiller (T)
In the package of NAVY 6.0T, the Tiller is not mounted on the outboard
motor prior to delivery. Users can mount it by one simple step:
Align the Tiller to the mounting recess of the outboard motor in the direction
of the arrow and plug in the Tiller until a click sound is heard.
Not to jam the outboard calbe

5 Remote Control / Tiller
The Remote Control/Tiller is used for starting and stopping the NAVY
outboard motor, adjusting the speed of the motor, configuring the battery
parameters, displaying the system information and messages, etc. The
Remote Control/Tiller is powered by either solar power or the built-in lithium
battery. Both Remote Control and Tiller wirelessly communicates with the
outboard control system built in the main outboard motor. The only functional
difference between Remote Control and Tiller is the steering method
: t
he
Tiller itself owns the steering capability, while the Remote Control requires
an additional steering wheel to help steer.
