1 Safety Information
1.1 Outboard motor safety
1.11 Propeller
People can be injured or killed if they come in
contact with the propeller. The propeller can
keep moving even when the motor is in
neutral, and sharp edges of the propeller can
cut even when stationary. Stop the motor when
a person is in the water near you. Keep people
out of reach of the propeller, even the motor is
off.
1.12 Rotating parts
Hands, feet, hair, jewelry, clothing, PFD
(personal flotation device) straps, etc. can
become entangled with internal rotating parts
of the motor resulting in serious injury or
death. Keep the top cowling in place whenever
possible. Do not remove or replace the cowling
with the motor running. Only operate the
motor with the cowling removed according to
the specific instructions in the manual. Keep
hands, feet, hair, jewelry, clothing, PFD straps,
etc. away from any exposed moving parts.
1.13 Electric shock
Do not touch any electrical parts while starting
or operating the motor. They can cause shock
or electrocution.
1.14 Modifications
Do not attempt to modify this outboard motor.
Modifications may reduce safety and
reliability, and render the outboard unsafe or
illegal to use.
1.2 Boating safety
This section includes a few of the many important
safety precautions that you should follow when
boating.
1.21 Alcohol and drugs
Never operate after drinking alcohol or taking
drugs. Intoxication is one of the most common
factors contributing to boating fatalities.
1.22 Personal flotation devices
Have an approved personal flotation device
(PFD) on board for every occupant. we
recommend that you must wear a PFD
whenever boating.At a minimum, children and
non-swimmers should always wear PFDs,.
Everyone should wear PFDs when there are
potentially hazardous boating conditions.
1.23 People in the water
Always watch carefully for people in the
water, such as swimmers, skiers or divers
whenever the motor is running. When someone
is in the water near the boat, stop the motor
immediately.
1.24 Passengers
Consult your boat manufacturer’s instructions
for details about appropriate passenger
locations in your boat and be sure all
passengers are positioned properly before
accelerating.

All rights reserved Golden Motor Technology Co., Ltd. 2019
2
Standing or sitting in non-designated
locations may result in being thrown either
overboard or within the boat due to waves or
sudden changes in speed or direction.
Even when people are positioned properly,
alert your passengers if you must make any
unusual maneuver. Always avoid jumping
waves.
1.25 Overloading
Do not overload the boat. Consult the boat
manufacturer for maximum weight and
number of passengers. Be sure that weight is
properly distributed according to the boat
manufacturer’s instructions. Overloading or
incorrect weight distribution can compromise
the boats
handling and lead to an accident, capsizing
or swamping.
1.26 Avoid collisions
Scan constantly for people, objects and other
boats. Be alert for conditions that limit your
visibility or block your vision of others.
Operate defensively at safe speeds and keep a
safe distance away from people, objects and
other boats.
·Do not follow directly behind other boats or
Water skiers.
·Avoid sharp turns or other maneuvers that
make it hard for others to avoid you or
understand where you are going.
·Avoid areas with submerged objects or
shallow water.
·Ride within your limits and avoid aggressive
maneuvers to reduce the risk of loss of control
and collision.
·Take early action to avoid collisions.
Remember, boats do not have brakes, and
stopping the motor or reducing throttle can
reduce the ability to steer. If you are not sure
that you can stop in time before hitting an
obstacle, apply throttle and turn in another
direction.
1.27 Weather
Stay informed about the weather. Check
weatherforecasts before boating. Avoid
boating in hazardous weather.
1.28 Passenger training
Make sure at least one other passenger is
trained to operate the boat in the event of an
emergency.
1.29 Laws and regulations
Know the marine laws and regulations where
you will be boating and obey them. Several
sets of rules prevail according to geographic
location, but all are basically the same as the
International Rules of the Road.The motor
controllers are programmable via
smart-phones to setup speed limit, maximum
current, lower voltage limit as you desire to
meet your needs and local authority's
regulations.

2.7 Battery Selection
How do I determine the capacity of the
battery pack needed?
Battery is the new form of "fuel" for electric
propulsion outboards, you never need to go to
gasoline station to refuel your outboard
anymore. You only need to recharge your
batteries at home or docking place.
Once you've chosen an electric outboard that
properly fits the weight and efficiency of your
loaded boat, the next task is to size the battery
bank that will store the energy to drive it. The
size of the battery bank will depend on the amp
draw you plan to regularly place upon it and the
range of miles you desire to travel. It is not easy
to know the current draw before you try it as
each boat is different from others in hull shape,
length, load, speed and daily operation hour you
want, not like electric cars which is fixed for
each car model in factory. Our expandable
battery module will make your life much easier
to determine how big the battery bank you need
to meet your purpose. You can just invest one
battery module first to test boat performance
with electric propel outboard and find out
accurate amp draw for your special boat setup
in different speed. After initial boat trial testing,
then you can easily figure out how many such
battery modules required to get the boat speed
and travel duration you want. You can easily
parallel connect multiple expandable battery
modules to form a larger capacity battery bank.
Each battery module is light weight for one
person to carry around. You can always buy
more standalone modules as you need them.
Each module has its own battery management
system (BMS) and charger.
We choose the most safe LiFePO4 battery cells
for our expandable battery modules, the materials
used inside cell will not cause any fire or
explosion. The quality of cell is very consistent
and can last more than 2000 charging cycles. Its
C-rating is 3 times, that means a single 48V50AH
module can output 150A continuously. That's
why you can just buy one or two battery modules
to test the outboard motor performance and amp
draw.
Why we choose 48V system for outboard motor
and battery pack, because it is safe for human and
easy to pass local government regulations.
Of course, you can always use other type of
batteries you can find locally, as long as its output
voltage is 48V, and capacity is enough to drive
the electric outboards.

3Installation and Operation
3.1 Installation
3.11 Installation indication
Your dealer or other person experienced in
proper outboard motor mounting should show
you how to mount your outboard motor.
There is no more long shaft and short shaft
differences, as EZ outboard products are user
adjustable in transom length to cater for
different boat installations, or boat loads which
may change from time to time. This feature
makes boat builders, owners and outboard
dealers life much easier, no more confusion on
shaft lengths, no more excessive stock for
long, medium and short shaft outboards!
The outboard motor should be mounted so that
the boat is well balanced. Otherwise, the boat
could be hard to steer. For single-motor boats,
mount the outboard motor on the center line
(keel line) of the boat.
Center line (keel line)
3.12 Mounting height
To run your boat at optimum efficiency, the
water resistance (drag) of the boat and
outboard motor must be made as little as
possible. The mounting height of the outboard
motor greatly affects the water resistance. If
the mounting height is too high, cavitation
tends to occur, thus decreasing the propulsion;
and if the propeller tips cut the air, the
motor speed will rise abnormally and cause the
motor overheat. If the mounting height is too
low, the water resistance will increase and
thereby reduce motor efficiency. Mount the
outboard motor so that the anti-cavitation plate
is between the bottom of the boat and a level
25 mm (1 in) below it.
Test runs at different heights can help
determine the optimum mounting height.
Consult your dealer or boat manufacturer for
further information on determining tnting
height.
