• Ensure that you stand stably when attaching your propulsion.
• Mount the motor only on land. Mounting the motor in the water may result in material damage.
• Do not lift the WaterWorld system alone, and use a suitable lifting device.
• Connect the throttle and batteries only after mounting the propulsion system on the boat.
• Drilling holes in the hull of the boat can potentially weaken the hull structure. This should be
compensated for by adding extra crossbeams, frames, or other reinforcements.
• Depending on the hull structure, a sufficiently large backing plate may be needed between the hull
and the locking nuts inside the boat. Ensure that the boat’s hull is stable enough to withstand the
drive unit and the resulting propulsive forces.
Applying antifouling to the motor is not allowed.
Remove the motor covers from the motor and carefully place them in a safe location.

vibrations in the boat and compensates for imperfections caused by the quality of the propeller
shaft system or the alignment.
WARNING! If the propeller shaft is directly mounted on the motor with a rigid
connection, the motor must be very well aligned to prevent damage to the electronics
and connectors. Never hit the propeller shaft with a hammer, as this can damage the
bearings in your motor! Use a puller for removing the propeller.
WARNING! For a WW 7.5, WW 10.0, or WW 20.0 motor in a heavy boat or for professional
use with many sailing hours, it is recommended to use an external thrust bearing. This
ensures that the rubber motor mounts and the thrust bearing in the motor are not
excessively loaded over time. If you have any doubts, please contact your supplier.
The motor controller of WaterWorld comes with a red and black battery cable already attached
to the motor controller side. The red cable on the positive side is connected to the relay.

We recommend and use the following cable thicknesses:
• 4.0kW: 35mm2 cable
• 7.5kW: 50mm2 cable
• 10.0kW: 70mm2 cable
• 20.0kW: 90-120mm2 cable
You can find more information about cable thickness on page 27 of this manual.
If you are going to use cable lengths longer than 5 meters, we recommend using thicker wiring.
The motor and controller are cooled by fans: two or four units at the back of the controller,
depending on the motor power (visible at the front of the system), and one on the motor. Ensure
that there is free airflow to dissipate heat. The air is drawn in at the front of the motor housing or
compartment and expelled at the rear. If necessary, ventilation grilles should be mounted at the
top on the side to allow for the intake of fresh air and the exhaust of warm air.
WARNING! WaterWorld assumes no responsibility for performance loss,
damage, or other issues due to inadequate system ventilation.
WARNING!
The WaterWorld propulsion system is best installed using the following step-by-step plan:
WARNING! If you choose to mount the motor without vibration
dampers, it is crucial that the motor is very well aligned with the shaft,
even if you use a flexible coupling. Additionally, this may lead to extra
noise, especially in aluminum boats.
CAUTION! Due to the weight, it is best to hoist the WW 7.5 or WW
10.0 into the boat. For this purpose, you can rotate the included
lifting eye, as shown in the image, also located at the top of the
motor where threaded holes are provided. You can use a hoist to
lift and lower the motor using this eye.
WARNING! Do not lift the WaterWorld system alone, and use a suitable lifting device.
The side supports on the motor are supplied with the supports pointing downward. In most cases,
these should be reversed, and the motor will hang in the supports as shown in these two examples:
In the standard configuration, the motor and controller are mounted in a single frame, and
these components are already connected to each other from the factory. You don’t need to
do anything about it. If there isn’t enough space for the controller directly behind the motor,
or if batteries are placed above the motor, you can mount the controller separately in another
location on the boat. To do this, it can be removed from the frame, and the rear part of the
frame can also be removed on both sides. The phase cables may be extended by a maximum of
50% from the factory length. Always consult an expert for this.
WARNING! If you want to mount the controller externally from the motor, this must be
done in consultation with WaterWorld by a certified installer!
