Boat Rigging & Product Installation
Boat Rigging Guides
Battery Selection
For safety and compliance reasons, we recommend that you follow
American Boat and Yacht Council (ABYC) standards when rigging your boat.
Altering boat wiring should be completed by a qualified marine
technician. The following specifications are for general guidelines
only.
CAUTION: These guidelines apply to general rigging
to support your Minn Kota motor. Powering multiple motors or additional
electrical devices from the same power circuit may impact the
recommended conductor gauge and circuit breaker size. If you are using
wire longer than that provided with your unit, follow the conductor
gauge and circuit breaker sizing table below. If your wire extension
length is more than 25 feet, we recommend that you contact a qualified
marine technician.
An over-current protection device (circuit breaker or fuse)
must be used. Coast Guard requirements dictate that each
ungrounded current-carrying conductor must be protected by a manually
reset, trip-free circuit breaker or fuse. The type (voltage and current
rating) of the fuse or circuit breaker must be sized accordingly to the
trolling motor used. The table below gives recommended guidelines for
circuit breaker sizing.

Regulations: 33 CFR 183 – Boats and Associated Equipment ABYC E-11: AC
and DC Electrical Systems on Boats

This conductor and circuit breaker sizing table is only valid for the
following assumptions:
- No more than 3 conductors are bundled together inside of a sheath
or conduit outside of engine spaces.
- Each conductor has 105° C temp rated insulation.
- No more than 5% voltage drop allowed at full motor power based on
published product power requirements.
*Wire Extension Length refers to the distance from the batteries to
the trolling motor leads.
