1.4 Important Notes
1. Check the status of the outboard and battery level before each trip.
2. The distance and speed value displayed is measured by Global
Positioning System (GPS), there may exist small errors due to GPS signal
strength degradation or some external environment conditions like
currents, winds and change of course.
3. Ensure the top of outboard is uncovered to avoid GPS signal attenuation.
4. Familiarize yourself with all the outboard operations, including starting,
steering, stopping, trim adjusting and tilting.
5. Only adults who have fully read and understood this manual are allowed
to operate this product.
6. Follow the boat manufacturer’s instructions to choose a suitable outboard.
Do not overload neither the boat nor the outboard.
7. Stop the outboard immediately if someone falls overboard during the trip.
8. Protect the battery from dropping into water or short-circuiting.
9. Follow the battery manufacturer’s instructions and pay attention to short
circuit, over-heat, over-charge and over-discharge.
10. Operate the outboard only when the propeller is underwater.
11. Tilt up the outboard motor above water after use.
12. Wash the outboard in time with fresh water after sailing in salt water.
13. Clean all electronic contacts with contact spray about every two months.
14. Do not leave the outboard in water if the boat is driven by other power
such as sailing or rowing.
15. An error code will display on the panel if the outboard malfunctions. Put
the throttle to zero position and turn off the main switch, then refer to
Chapter 5.6 Warning Messages for details and solutions.
16. For safety consideration, the system will shut down automatically when
the temperature of the motor or driver rise too high or the battery voltage
drops too low during operation.
17. Users are responsible to assemble the propeller and steering wheel. If
other assembly or disassembly is required, please contact your dealer.
ePropulsion accepts no liability for any damage or malfunction caused by
operations that violate this manual.

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 lead-
acid 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 conguration.

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 conguration. 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

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 efciency.
In general, the optimal mounting height is affected by the specic 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.

17
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.
Figure 3-5
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
while mounting the tiller.
Figure 3-6
To detach the Tiller: press the release buttons (Figure 3-7) on both sides of the Tiller
and plug it out.

Figure 4-1
When using non-NAVY batteries, users should congure the batteries
via Remote Control/Tiller for the rst time use, otherwise the batteries
may not work properly.
Avoid battery short-circuit during connection.
Outboard motor will stop working once the power cable disconnects.
Clockwisely rotate the main switch to power on the battery before use.
Users can also enlarge the battery capacity by connecting multiple
batteries in parallel.
The main switch and power cable are connected by the xing screws
that may loosen after long-time use. Loosen screws will lead to poor
contact. If this problem is discovered, open the back cover of the main
switch, and tighten the screws inside.
