2.3 Warranty information operation / installation
Incorrect installation, use of unsuitable accessories or variations in voltage voids the warranty.
Electrolysis is the decomposition of metals exposed to an electric current. When your boat is
connected to a shore power AC electrical system, it is also connected to an earth ground circuit.
This can cause an electrolytic current which causes the decomposition of all submerge metal. The
manufacturer’s warranty does not cover corrosion. Check and change anodes periodically.
WARNING – CAUTION – MOTOR OPERATION
Never operate the motor out of the water. Not even for a few seconds. When turning the key
switch, the electric motor turns at 600 revolutions per minute, even no gear is shifted. The electric
motor also operates the water pump to cool the engine. If the water intake below the antiventilation
plate is not in the water, the impeller of the pump will be destroyed within seconds. This can also
result in the damage to the seal of the gearbox.
To test your motor on land, the propeller needs to be dismantled and the water intake has to be put
in a water tank at least 10 cm under water level.
Alternatively for a short run to clean the water system from salt water, a outboard flusher can be
used. Sufficient water pressure has to be available. If water does not drain from water outlet after
starting the motor, there is no sufficient water pressure. Stop immediately!

3) Installation of remote controlled motors
3.1) Throttle and gear shift
For throttle and gear shift operation a single lever power engine control needs to be installed on
the boat. Standard stainless steel throttle and gear shift cables to be used.
Side view to throttle and gear shift connection
To fix the controller cables, unlock the 3 bolts “A” to remove the cover.
The remote operated outboard motor is equipped with a electronic throttle position encoder and an
adapter for the gear shift cable. Both adapters are equipped with a 10 – 32 UNF standard thread.
The throttle and gear cable need to have a nut to secure the connection.

To fix the cable to the throttle position encoder, the connecting rod can be turned. The u-head of
the gear shaft can be removed to fix the cable.
The gear shift has to be adjusted that at the neutral position of the single lever, the u-head is in
neutral position too and the bolt can be easily inserted.
For fine adjustment the thread at the end of the cable can be turned and secured with the nut.
The throttle possition encoder has to be in the neutral position where marked when the single lever
is in neutral position (see picture). The throttle is activated when the rod is moved in the encoder
tube.
If this setting is not correct, the motor cannot be started. The fine adjustment can be done by
turning the thread of the cable or by moving the encoder by loosening the clamp.
The key switch, the boat kill switch and the multi functional display are supplied separately for the
remote controlled engine. These have to be mounted to the helm stand with the supplied cables.
(See 3.3)
Suitable cables and single lever power engine controls can be purchased from aquawatt or marine
supplier. Installation on the boat has to be done by an experienced person.
Installation and maintenance of lever and cables are not part of this manual. Please refer to the
supplier‘s instructions.

Transom support mounting
Alternatively the steering cable can be fixed at the transom of the hull. This needs a special
support unit to hold the cable to the transom.
The installation and connection of the steering system should only be done by an experienced
specialist.
DANGER
Faulty installations of steering, gear and throttle can result in severe or deadly injuries.
External gear and steering systems have to be maintained according to the instructions of the
manufacturer. This is not part of this manual.

3.3) Display & switches
The wiring – kit is supplied with the 12R motor. If the cables are removed from the switches,
ensure that they are remounted exactly as supplied.
Install the display; the key switch and the emergency switch to a stable, non conducting surface
and make sure, the backside of the units are not exposed to water or humidity.
(Installation just for demonstration purposes)
Optional ampere hour meter recommended (use system capable to measure 60 V DC / 300 A or
90 V DC / 300 A). This is included in the lithium battery packs, if purchased from aquawatt.
The shunt included with the meter has to be installed between the negative battery pole and the
fuse / main switch. The battery charger has to be connected on the fuse side and not directly to the
negative battery pole, as otherwise the meter cannot count the amp hours charged.
See separate manual for battery installation and operation instructions.

4) Operational area
The aquawatt motor can be used in fresh water and if equiped with suitable anodes in salt water. If
used in salt water, it has to be assured, that no salt water runs under the cover. The anode has to
be cleaned a replaced if 25% is corroded.
After the use in salt water, we recommend to flush the cooling system (see section 2.2 for details).
Never run the motor with removed hood!
If the boat is moored, the motor should always be lifted out of the water and set in the direction
where wind and waves head to.
ATTENTION
The motor should only be used in clear water which is not colder than 10 degrees Celsius and not
warmer than 30 degrees Celsius. Variations of these limits can result in damage of the motor and
the cooling system.
5) Drive with the aquawatt outboard motor
DANGER
As boat operator you are fully responsible for the security of all passengers on board as well as to
any other water craft, swimmers or animals within your area of operation.
You have to be aware of all rules & regulations for operating a water craft. The detailed knowledge
of this operator’s manual and the instructions for the boat and all equipment is a very important
part of your responsibility.
A swimming person cannot avoid very quickly even if a boat runs at low speed. Therefore you have
to switch off the motor if a person is close to your boat.
ANY CONTACT WITH A MOVING VESSEL, THE PROPELLER OR ANY OTHER PART OF THE
MOTOR OR THE BOAT CAN LEAD TO SEVERE INJURY.
Always equip your boat with safety gear

5.1) Turn-on procedure
 Turn-on the battery main switch
 Connect boat kill key to the switch (see 2.1.)
 Turn tiller handle to the slow position or shift the engine control to the neutral position
 Move the gear switch to neutral position or the engine control lever to neutral position
 Switch the key to the ON position
The motor starts operating at 600 turns per minute to ensure the water flow through the cooling
system.
The motor will not start, if a gear is shifted, the throttle is not in lowest or neutral position or the
boat kill switch is off. If no gear is switched, the motor power cannot be increased!
If the motor runs after approximately 10 seconds cooling water has to run out of the water exit. This
has to be checked on regular bases, as without water flow, the motor and the controller will be
damaged due to overheating!

5.2) Drive forward
Turn the hand throttle to minimum speed or the engine control to the neutral position.
Switch the gear to forward (in the forward direction) or move the engine control to forward.
The boat starts to move slowly even the hand throttle has not been turned.
To accelerate turn the hands throttle or move the engine control slowly.
We recommend to not operate the engine at full power (300 Amps on display) for more than 20
minutes depending on the batteries and cables used for installation. If you need full power all the
time, 2 x 32.5 mm2 cables should be used for all connections from the controller to the batteries.
5.3) Reverse
The same procedure as driving forward, but move the gear switch backwards or the power engine
control backwards. Do not drive backwards at high speeds!
When changing from the forward to the reverse gear always stop at the neutral position for two
seconds. ONLY SWITCH GEARS WHEN THROTTLE IS IN IDLE / NEUTRAL POSITION.
CAUTION
Changing gears at high speeds can cause heavy damage or injury!
5.4) Safety Switch
If the lanyard is pulled from the kill switch the motor stops immediately.
The line should be fixed to the operator in case of loss of control or
passengers go overboard.
The use of the lanyard system is recommended but we need to
highlight the risk of a sudden motor stop.
CAUTION
An accidental activation of the boat kill switch can cause loss of control and injury to the
passengers!
5.5) Multi functional display
If only the yellow light flashes, this shows a normal operation.
The display indicates the most important information. Besides the selected information, the battery
charge status is always shown on the top of the screen between 0 (empty) and 1 (full).
When turning the key switch, the system shows the motor rotation speed per minute.
To change to another reading, push the button to the right. To move back, push the left button.
