AquaCraft EP1 Electric Outboard Motor - Manual (Page 2)

Thank you for purchasing the AquaCraft EP1! We at AquaCraft
know how exciting a new hobby purchase can be and we know
you’re anxious to get started, but please take time to read these
instructions carefully and completely before attempting to
operate your motor. This manual contains the instructions you
need to safely operate and maintain your motor. As with any
hobby, there is the possibility of injury. Arming yourself with
knowledge is the best way to avoid injury.
PLEASE NOTE: Your hobby dealer cannot accept a return on
the EP1 outboard unit after it has been used.
All pictures, descriptions, and specifications found in this
instruction manual are subject to change without notice.
AquaCraft maintains no responsibility for inadvertent errors in
this manual.
A template has been provided for you on page 3 of this
manual. This will help to accurately place the mounting holes.
Mount the outboard unit in the center of the rear of the boat
and so that the surface ride plate is even with the bottom of
the transom as shown.
The steering control arms of the EP1 outboard unit have been
outfitted with 4.8mm balls, but will accept clevis or Z-bend
links as well. You can attach to either control arm or both but
it is best, of course, to do whichever makes your boat perform
to its fullest potential.
When you are through operating your boat for the day, be sure
to perform these basic maintenance procedures. This will
prolong the life of the EP1 Outboard motor and help to ensure
trouble-free running. Be sure to turn the power “OFF” to
your boat and transmitter before performing any
maintenance.
• Flip your boat over and shake any excess water from the
motor compartment.
• Locate and remove the “end cap” (see “Exploded View”
on page 4) at the base of the outboard by turning it
counterclockwise. This will allow you to release any
water trapped in the gear housing. The “bullet” at the
front of the outboard unit is also removed by
counterclockwise rotation. This allows access to the front
shaft bearing.
• Make sure the propeller and drive dog are free of moss.
After every 10-12 hours of leisurely run time or after a day of
competition, it is a good idea to disassemble and re-lubricate
the gears, shafts, and bearings of the outboard unit with fairly
heavy-duty grease (not oil). Be sure to wipe away any old
grease but DO NOT use any de-greasing agents. Refer to the
“Exploded View” on the back cover for an assembly diagram.
You can increase the performance of the AquaCraft EP1 by
adjusting the ride height or the thrust angle of the propeller.
Making slight adjustments can make major differences, so it is
a good idea to keep a record of any adjustments you make
and how they affect performance. In addition to these
adjustments, performance may also be affected by the weight
distribution of your onboard radio gear, speed control, battery
pack(s), etc…
GO FASTER
The EP1 comes equipped with a 27-turn stock motor but can
be upgraded by replacing it with almost any 550-can size
motor. Be sure to consult the instructions for your speed
control unit to determine motor upgrade limits.
1. After clipping or de-soldering the red (+) and black (-)
motor wires, simply remove the two 3 x 8mm hex head
screws on the underside of the motor compartment and gently
lift out the stock motor. Be sure to remove the water-cooling
coil and jacket from the stock motor and place it on the
upgrade motor before installation.
2. Solder the red (+) and black (-) motor wires to the proper
wiring lugs and attach the upgrade motor to the outboard unit
with the two 3 x 8mm hex head screws.
PLEASE READ BEFORE running the EP1 on your model:
• NEVER attempt to swim after a stalled or capsized boat!
Wait patiently for the wind currents to return the boat to
