Description
This range of electric outboards are unique in their design. Using a D.C. brushless, water-
cooled 48v electric motor, which is mounted horizontally on top of the outboard leg. Drive is
transferred by a heavy-duty toothed belt to the prop shaft. This gives an efficient and trouble-
free method of power delivery. The outboard leg has internal waterways built into it through
which cooling water (with anti-freeze) is pumped, circulated through the motor, and flows
down the inside of the leg, to be cooled by heat transfer. There is no traditional type impeller
to wear out or change. Salt, silt, and sand does not enter the motor and, as long as the anti-
freeze levels are maintained, there is no danger of frost damage in the winter. This results in
your electric outboard requiring far less maintenance than a conventional petrol unit.
They can be tiller or use an inboard shift and steering system, and optional propellers are
available. Bluetooth performance monitoring system is used to indicate main parameters.

SECTION 1 –Safety Precautions
1. General
NOTICE:
NEVER PERMIT ANYONE TO OPERATE THE OUTBOARD WITHOUT PROPER
TRAINING.
Ensure that the engine battery isolator switch is in the off position before connecting the
battery, carrying out any maintenance or repairs. Also, when the outboard is not in
use.
2. Lifting
DANGER:
CRUSH HAZARD! NEVER STAND UNDER A HOISTED ENGINE. IF THE HOIST
MECHANISM FAILS, THE ENGINE WILL FALL ON YOU, CAUSING SERIOUS INJURY
OR DEATH.
•Note: Suitable safe lift equipment must be used to lift, move, and mount the outboard
onto the boat.
•The batteries used for the outboard will be heavy. Make sure safe lifting procedures
or suitable cranes or hoists are used when moving and installing them.
3. Rotating Parts
WARNING:
SEVERE HAZARD! KEEP HANDS AND OTHER BODY PARTS AWAY FROM
MOVING/ROTATING PARTS. WEAR TIGHT FITTING CLOTHING AND KEEP YOUR
HAIR SHORT OR TIE BACK. REMOVE ALL JEWELLERY BEFORE COMMENCING
WORK. CHECK BEFORE STARTING THE OUTBOARD THAT ANY TOOLS OR RAGS
USED DURING MAINTENANCE HAVE BEEN REMOVED FROM THE AREA.

RDG603A74 - Issue 4 Page 11 of 97
The outboard and its accessories are not intended to be put into operation until they are
integrated into the boat as a whole. The top cowl must always be fitted whilst the motor is
running.
4. Propeller
CAUTION
•The propeller has sharp edges which can cause injury even when it is stationary. If
there is someone in the water near the motor, it must be switched off.
•If the propeller is damaged, itmay become unbalanced and cause either bad vibrations
or the outboard to fail. Do not use the outboard in this situation.
5. Electrics
CAUTION
•Do not touch any electrical parts while operating the motor. The electrical parts may
cause shock or electrocution.
•Ensure all electrical connections are insulated against accidental short circuit.
6. Batteries
DANGER:
EXPLOSION HAZARD! NEVER SHORT OUT THE BATTERY TERMINALS,
INCLUDING WHEN CHECKING THE REMAINING BATTERY CHARGE THIS WILL
RESULT IN A SPARK AND MAY CAUSE AN EXPLOSION OR FIRE.

RDG603A74 - Issue 4 Page 12 of 97
WARNING:
BURN HAZARD! BATTERIES CONTAIN SULPHURIC ACID. NEVER ALLOW
BATTERY FLUID TO COME IN CONTACT WITH SKIN, EYES OR CLOTHING. SEVERE
BURNS COULD RESULT. MAKE SURE THE CORRECT PERSONAL PROTECTION
EQUIPMENT IS WORN.
•Batteries can produce explosive gases; keep sparksand flames away from the battery.
NO SMOKING
•Lead acid batteries contain sulphuric acid; if splashed on skin or eyes, flush well with
water and seek medical advice.
•Keep battery tops and battery compartment ventilated at all times.
•If disconnecting the battery; remove the earth lead FIRST; and re-connect it last.
•If charging the battery; ensure that the charger is switched off before connecting and
disconnecting.
•Do not tip the battery on its side.
•Please see label on battery or manufacturer’s instructions for specific information.
•A battery master (on/off) switch must be installed in the system.
7. Safety Lanyard
WARNING:
•The magnetic safety lanyard tag should always be attached to the stop switch area
on the outboard tiller or remote shifter and the person operating the boat before the
motor is started. This will prevent the outboard from operating if the operator falls
overboard or leaves the helm.

RDG603A74 - Issue 4 Page 13 of 97
Figure 1: Safety Lanyard
The outboard will not operate if the safety lanyard is not in place. Ensure there
is a spare one on board the boat and that passengers know where it is located.
8. Motor Overload
•If the motor is excessively overloaded (by either extended running at high speed or
using a propeller which is too big for the application) the motor will stop.
•If the motor stops all drive will be lost, which may be hazardous.
•If the motor stops, move the speed control lever to the stop position. Slowly move the
speed control to the drive position which will start the motor again.
•Continue at a reduced speed until the initial cause of the overload has been resolved.
9. Modifications
Do not attempt to modify the outboard motor as this is likely to reduce safety and reliability.
Any modifications will mean that the outboard will not be liable for warranty and maybe illegal
to use.
10.Boat
•Ensure the boat, that the outboard motor is being fitted to, has the capability of
accommodating the power and weight of the unit. (including the batteries).
•Ensure that any requirements of the boat manufacturer are adhered to.
•Consider location of the batteries in regard to weight distribution within the boat.
11.Passenger Training
•Ensure that at least one Passenger is trained to operate the boat in the event of an
emergency.

RDG603A74 - Issue 4 Page 14 of 97
12.Terminal Crimping
Ensure that a professional type crimping tool is used for crimping all heavy-duty cable
connections. Failure to do so can result in poor performance, system failure, terminal
overheating or in some cases melting of plastic terminal plugs or even fires.
13.Applicable Standards
Ensure that the fitting and installation of the electric outboard motor, batteries, battery
storage, cables and control systems comply with all relevant local, national, and international
standards.

SECTION 3 –Installation
NOTICE:
REFER TO THE BARRUS MANUAL PRIOR TO INSTALLING THE ENGINE.
1. Unpacking the Outboard Motor
•The outboard motor will arrive in a wooden box. Section 8.3 details shipping weight
and packaging dimensions. Use suitable personal protective equipment for unboxing.
Figure 7: How the outboard motor will arrive
•Stand the box upright as shown in Figure 7.
•Use a screwdriver to open the wooden box carefully. Don’t damage the wooden box.
•Make sure to remove all screws or staples from the box.
•Using a crane, two people will be required to remove the engine from the box.
Figure 8: Opening the wooden box

RDG603A74 - Issue 4 Page 18 of 97
•Check to make sure the following parts are in the box:
1. Outboard Motor
2. Anderson Type Cable Connector (Qty 1)
3. Safety Lanyard
4. Transom Mounting Bolts and Tools
5. Speed and Direction Control Lever and Steering Kit (Remote Steering Only)
Figure 9: Items in the wooden box
Note: The outboard does not arrive as pictured above. Some assembly is required, such as
fitting of the propeller and skeg. Propeller fitting instructions can be found on pages 45 and
46.
Note: There is a right-handed speed and direction control lever available at an additional
cost.
•For remote steering/control application, the steering kit should contain:
1. Square Rubber bung
2. Steering Arm
3. Locking Spacer
4. Grub Screw
5. Steering Arm Left
6. Threaded Adjuster

•The rigid set up (Figure 10) uses parts 12 and 13 in the steering kit list and attaches
to the motor in two places.
•The flexy set up (Figure 11) uses the existing steering bracket that is also used for
the tiller control.
2. Filling Outboard Motor with Coolant
•Ensure the propeller is not fitted.
•Remove the engine cowl from the outboard motor. (Figure 2)
•Remove the coolant cap from the outboard motor. (Figure 12)
•Switch the outboard on, using the on/off switch (Figure 3, button 5) the button will then
be illuminated green, this starts the pump, then immediately begin filling with coolant.
•Fill the coolant tank with standard high-quality antifreeze and clean water at 50:50 mix
ratio.
Ensure the engine is in the neutral position. Do not engage forward or
reverse.
•After one minute switch off the power then add coolant again.
•Switch on the power again to allow the pump to circulate the coolant.
•These stages may need to be repeated multiple times to ensure the tank is full, and
all air is removed.
Ensure the coolant tank is full before operating the outboard.
