1. Use and safety
Mitek motors are designed for safe and reliable operation.
Please read this manual carefully before operating your motor.
Failure to comply with the following instructions may cause personal injury or material damage.
Mitek srl declines responsibility due to negligence and non-observance of the rules and instructions
contained in this manual. We also decline responsibility for damage caused by improper use of the
product.
1.1. Important information for safe motor operation
•Before starting a trip, check the status and operation of the motor (including the safety switch which
will act as an emergency stop if necessary).
•Familiarise yourself with all the motor control elements.
•The motor should be only operated by adults who have been instructed to do so.
•Comply with the boat manufacturer's instructions regarding the permitted motorisation of your boat.
Do not exceed the stated loading and power limits.
•In the event of a person going overboard, stop the motor immediately.
•Do not start the motor if there are swimmers nearby.
•Solar panels or generators can be connected only in parallel with the battery bank
Mitek can refuse warranty claims if the purchased item was in any way modified or equipped with parts or
accessory items which are not expressly authorized by Mitek.
Warning: In addition to this information, please pay attention to everything in this manual.
1.2. General Warnings
In addition to the following warnings, please take into account all the information in this manual to prevent
damage to your outboard:
•Protect the connectors and the main switches from moisture.
•The motor unit must be lifted or taken out of the water if the boat is driven by other means (e.g. sailing,
using other motors) to prevent damage to the electronics.
•Operate the propeller only when it is underwater to avoid damage to the cooling system.
•After use in salt water, rinse the outboard with fresh water and be careful not to get the electronic
components wet.
•Before leaving the boat, remove the safety key and disconnect the power connector to prevent
accidental starting of the motor and battery discharge when not in use.
•Disconnect the power connector with safety insulated gloves and do not operate the motor if exposed
to flood waters.
•Check the sacrificial anode periodically, every 6 months at the latest, and replace it if necessary.
•Always use chargers with galvanic isolation when charging batteries. Your dealer will be able to advise
you accordingly.

2. Operating manual
2.1. Outboard Installation
Warning: installation should be done by experienced personnel. Please make sure that the installation is
carried out on steady footing and that the battery connector is not connected to the motor.
Place the outboard on the transom or
outboard mount on the centreline of the
boat and tighten the two clamps securely.
Warning: to avoid damage or loss of the
motor, check the tightness of the two
clamps frequently.
Attach a strop or retaining chain to the eyelet of the outboard if the boat has one.
Check that the motor axis is perpendicular to the water and
if necessary move the pin to achieve the correct inclination
(trim).
Please note that this function is not available for models
MO 2.6HP S and MO 4.5HP S.
To lock the steering function of the engine (e.g. on boats
equipped with a rudder) tighten the side screw.
Warning: once the engine has been installed and the boat has reached its maximum load capacity, make
sure that there is no danger of water entering the boat from the transom when water rises due to waves;
this could cause loss of stability and be very dangerous.
2.2. Batteries
The best choice for your electric outboard motor is to install batteries sold or recommended by Mitek.
However, the full range of Mitek MO outboards can be powered with different types of batteries like lead
acid, AGM, Gel, and lithium batteries, as long as they achieve the desired capacity according to the needs
and autonomy required. It is advisable to contact the service centre for all necessary information.

2.3. Emergency situations
There are two ways to stop the motor rapidly in an emergency:
•Move the throttle lever to 0: the electronics are set to stop the propeller within 1 second
•Remove the safety key.
2.4. Setting outboard motor mounting height
For correct installation, check the installation height in relation to the boat's
keel.
If the outboard is mounted too high on the transom, cavitation tends to
occur and this may result in loss of efficiency, increased noise and damage to
the propeller; if the mounting height is too low, the water resistance will
increase and thereby reduce engine efficiency. There is also a risk that the
outboard goes underwater.
The correct height of the anti-cavitation plate is 25mm below the bottom of
the boat.
The ideal height is influenced by the type of use and the geometry of the hull.
Please consult your dealer or boat manufacturer for more information.
The optimum mounting height of the outboard motor is affected by the
shape of the hull and the desired use.
Please consult your dealer or boat manufacturer for more information.
2.5. Pre-operation checks
•Check the integrity of the cables and electrical connections.
•Check that the batteries are charged and securely fastened in the correct position.
•Check that there is no water on the electrical connections and batteries.
•Check the gearbox and steering, they should be smooth.
•Check that there are no loose or damaged fasteners.
•Check the integrity of the propeller.
Warning: if any item in the pre-operation checks is not working properly, please contact our customer
service and have it inspected and repaired in order to avoid incidents.

2.6. Starting the motor
Warning: do not operate the motor out of the water, it could get damaged. Handle all electrical equipment
with dry hands .
•Attach the engine stop switch lanyard cord to a secure place (e.g. your wrist). Do not attach to
clothing that could tear loose.
•Set throttle to 0.
•Connect the battery power connector.
•Accelerate gently and check that there is a steady flow of water from the exhaust.
Warning: A continuous flow of water from the cooling water pilot hole shows that the water pump is
pumping water through the cooling passages. If water is not flowing out of the hole at all times while the
engine is running, over heating and serious damage could occur. Stop the engine and check whether the
cooling water inlet on the lower unit or the cooling water pilot hole is blocked. Consult your dealer if the
problem cannot be located and corrected. NB: On MO 2.6HP and 4.5HP models, there will be no water
flow when operating in reverse.
2.7. Tiller handle
To change direction wile operating your boat, move the tiller handle
to the left or right.

2.8. Adjusting the speed
To increase or decrease speed, turn the throttle grip.
2.9. Stopping the motor
To stop the motor, turn the throttle grip to zero (turn it clockwise completely).
2.10. Gear shift lever
The gear shift changes from motor to motor.
•MO 2.6hp and MO 4.5hp: to reverse, lock the engine tilt with the lever and press the "R" button.
Warning: to avoid damages in case of collision with the seabed, turn the throttle grip to zero and unlock
the motor tilt before moving the gear shift to forward.
•MO 6hp: to reverse, move the gear shift lever:
F = Forward
N = Neutral
R = Reverse
