BATTERY & WIRING INSTALLATION
BOAT RIGGING & PRODUCT INSTALLATION
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 qualifi ed marine technician. The following specifi cations are for
general guidelines only:
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 qualifi ed 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.

CONDUCTOR GAUGE AND CIRCUIT BREAKER SIZING TABLE

This conductor and circuit breaker sizing table is only valid for the following assumptions:
1. No more than 3 conductors are bundled together inside of a sheath or conduit outside of engine spaces.
2. Each conductor has 105° C temp rated insulation.
3. No more than 5% voltage drop allowed at full motor power based on published product power requirements.

NOTE:
Wire Extension Length refers to the distance from the batteries to the trolling motor leads. Consult website for
available thrust options. Maximum Amp Draw values only occur intermittently during select conditions and should not be
used as continuous amp load ratings.
