KARVIN 2700 S Operating instructions

KARVIN ELECTRIC OUTBOARD MOTOR
SERVICE INSTRUCTIONS
Dear customer,
you just bought a fully integrated outboard motor unit, which will fulfill your requirements fully.
The Karvin electric motor is more than an excellent accessory or auxiliary motor; it is a
“workhorse”, which can satisfy demands of both amateurs and professionals on the water.
The Karvin electric motor has many features not available even in gasoline outboard motors.
•silent
•simply to operate
•low maintenance
•very low operating costs
•light
•dependable
•ecologically friendly
Further features and advantages:
•The fastest and the most efficient electric outboard motor in the current world market.
•Two times lower consumption of electricity than comparable DC motors.
•81% efficiency.
•Suitable for use in conjunction with solar panels.
•High torque.
•Computer controlled motor operation.
•Continuous RPM regulation forward and reverse.
•Electronic key insures safety and security. Karvin motor will shut off if the operator falls
overboard and prevents also its starting by any incompetent person.
•Large illuminated display.
Electronic display shows important information, allowing the economical and efficient
operation of boat and motor:
•RPM (Rotations Per Minute)
•Actual current consumption
•Battery voltage
•Accumulated hours of operation (total number of hours the motor has been used)
•Audible and visual low voltage warning system. This system also shifts automatically the
motor into power conservation mode, preventing total discharge of batteries and insuring
a safe return to the shore.
Important warning for the operating person
•Never put the engine into operation when not being in the water.
•Don’t connect the battery to the terminal connectors, before the engine is hanged up in its
working position and fixed to the boat.
•Pay your attention to the correct incoming cable connecting polarity to the battery! If
it’s not the case, the motor electronical control will be destroyed.
•Control also if the incoming cables isolation is faultless, before you put the engine in
operation.

•Always disconnect the motor from the battery, before you start any control or any
eventually cleaning of the propeller.
•Avoid the complete motor fall in the water. In such a case, water could penetrate into the
electronically part of the motor and destroy it. If such a case occurs, don’t switch on the
motor before the nearest service center makes its control.
•The complete motor is resistant to humidity and rain, however not to a fall in the water.
•When not using the motor for any longer period, up tilt it out of the water.
•Every motor impact can cause its damage.
•Store the motor in a dry place within the winter season.
•In a case of the indication about the electronical key battery discharge, it’s necessary to buy a
new key in an authorized service center. Every key is encoded and that’s why you’ll need
to know the motor type as well as its production number for its eventual change.
•It’s recommended to keep the original transport carton for the case of any claim.
Important security warnings:
•Never touch the propeller when motor is connected to the battery.
•Don’t use your boat on places where it’s prohibited to go.
•Keep your watch on persons and objects in the water.
•Children and teenagers can use motor only in a presence of any adult person.
Assembling and motor setting-up
1. Motor and accessories completeness check-in

2. Propeller installation on the motor spindle
(For installation, use the attached adhesive. Apply the adhesive maximum of two threads of the bolt.)
3. Motor fastening to boat 4. Motor shaft correct setting-up

5. Motor position correct setting-up, by means of the stick for the trim angle adjustment
6. Motor hanging-up before the ground swell and its back floating.

7. Security motor lever blocking for boating in unknown shallow water.
8. Boating direction detent screw
9. Battery connection to the motor

Motor control

3. Remote control for electromotor ( type W ).
The principle of remote control of motor is similar to the control the motor on handle.
The only difference is that, the remote control unit and the display are placed in a box near the
steering wheel and connected by cable to the engine. For speed control of Karvin motor can use
electronic manual throttle, which can be connected to remote panel control by cable. When the
throttle will be connected to control panel then this icon will show on display. Before you connect
the throttle please be sure that throttle is in N position. When you disconnect the throttle or the
throttle will break down then you can use remote control panel to control the speed.
Steering of the engine is controlled via the steering wheel (link control – not part of engine).
4. Security and Starting Electronical Key
•Electronical key is an electr. sender, which switches off the engine automatically when
departs from the display (control unit) or which doesn’t allow to start the motor.
•Carry the key always hanged-up around your neck.
•By means of the switch ON/OFF you switch on the battery in the electronical key and the
control unit of the complete motor is activated.
•We recommend switching of the electronical key, by means of the switch ON/OFF, by
pressing it for 4 sec. at all long-term interrupted boating or after your boating is finished and
disconnect the incoming motor feed cables only after that. This way you safe battery and
extend its operating life.
•Never put the electronical key in the water intentionally.

Battery is an important part of the motor
1. Battery type
•We recommend traction gel batteries of capacity min. 80 Ah
2. Supply Voltage
SUPPLY VOLTAGE IS INDICATED ON THE MOTOR MANUFACTURING LABEL,
BY CONNECTION ANY HIGHER VOLTAGE THAN APPOINTED THERE, THE
MOTOR CAN BE DESTROYED.
3. Battery protection against its complete discharge
Special electronic indicated on time (audio and lighting signals) any critical battery voltage
drop and set up automatically the motor load into an economical mode for safe shore
reaching.
4. Battery charging
•We recommend using the original battery charger for concrete batteries type only
•We recommend charging batteries overnight always before each boating.
Motor Servicing
•Karvin electro motor doesn’t require any special service.
•In case of any pollution, dry it with any wet rubber only.
•In case of propeller and spindle pollution, remove first any eventual water plants and dirt
and then wash them with water only.
•Let your motor control after every 800 operating hours in a specialized service center,
eventually let overhaul the motor tightness.
! Attention !
•Please do not transport the motor in lifted position.
•Please use small amount of glue PERMABOND on M10 screw and strong tight.
•Please do not put glue on propeller.
