life jacket when sailing. When operating, tie the cable of the safety switch to a firm
position such as hand, foot or clothing. If accidentally left the steering position, the
cable will drag the switch and stop the in-boat machine.
12.Before each voyage, please be sure to check the state and battery power of the engine
on board.
13.Please report the sailing plan to relevant personnel (dock and family members, etc.)
before leaving the port
14.When moving inside the ship, watch carefully for swimmers and stay away from them.
Stay away from swimming areas.
15.Do not cover the GPS and 4G external antenna to avoid signal attenuation.
16.The distance and speed values shown are measured by the Global Positioning System
(GPS) and may be subject to minor errors due to weak GPS signal or changes in
external environments such as ocean currents, wind, etc.

3 Install the I-10 motor
3.1 Install the motor
The quality of installation plays a decisive role in the reliability of the whole system. Among
them, the output shaft in the center and the suspension is the most critical. If you want the
system to be stable and reliable, please refer to the following requirements for installation to
ensure that the equipment works in a good state.
3.1.1 Before installation
1. Check the materials:
① Motor: Check the I-10 machine structure to ensure that there is no loosening or
abnormality. Arrange the main power cables, 12V power cable, and communication cable and
fix them in appropriate positions for easy handling.
② Tools: Open-end wrench, wheelbarrow, gloves.
③ Accessories: 8 M10x45 hex bolts, 4 M10 hex nuts, 8 M10x18 hex bolts.
2. Confirm the drawing file of the motor:
I-10 dimensions are shown in the following. Before installation, please carefully check the size
to ensure sufficient installation space, accurate installation position, convenient adjustment,
to meet the installation requirements.

Suggestions for the mounting platform:
First, design the proper mounting platform according to the size model of the motor, the
space inside the ship and the position of the stern shaft. The size of the fastening hole of the
mounting platform is M10, and the size distribution is determined according to the position
of the fixing hole of the suspension support foot. The motor platform is firmly fastened to the
hull, and can bear a large thrust (greater than 3500N).
Pre-installation work:
① Confirm the motor model: motor size, weight, voltage, power and the current ship match;
② Design layout: read the user manual, need to consider the layout and design of the whole
system. Machine and related system components must be installed in the appropriate
position on the ship to ensure safe and efficient operation.
③ Simulate the installation process: according to the installation process of the user manual,
simulate the relevant process to ensure that the installation is feasible and the installation
process is low risk.
④ Clean the environment inside the ship: clean up irrelevant objects according to the
simulation process, keep dry and clean. Ensure that the installation process is smooth and
the commissioning process is normal.
Suggestions for lifting:
Before hoisting, sort out the cables and fix them on the motor. Suspend two feet around the
motor through the sling, complete the lashing of the rope, pass through the hook, adjust the
position of the hook, and test hoisting. In the test hoisting, the machine is stable without
tilting and shaking, then formal hoisting can begin.
1. Remove the cover. 2. Wrap the rope and hoist the machine
