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:
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 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.

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.
*Wire Extension Length refers to the distance from the batteries to the trolling motor leads.
sELECTing THE CoRRECT bATTERiEs
The motor will operate with any lead acid, deep cycle marine 12 volt battery/batteries. For best results, use a deep cycle, marine
battery with at least a 105 ampere hour rating. Maintain battery at full charge. Proper care will ensure having battery power
when you need it, and will signifi cantly improve the battery life. Failure to recharge lead-acid batteries (within 12-24 hours) is the
leading cause of premature battery failure. Use a multi-stage charger to avoid overcharging. We off er a wide selection of chargers
to fi t your charging needs. If you are using a crank battery to start a gasoline outboard, we recommend that you use a separate
deep cycle marine battery/batteries for your Minn Kota trolling motor.
Advice Regarding Batteries:
• Never connect the (+) and the (–) terminals of the battery together. Take care that no metal object can fall onto the battery and
short the terminals. This would immediately lead to a short and extreme fi re danger.
• It is highly recommended that a circuit breaker or fuse be used with this trolling motor. Refer to “Conductor Gauge and Circuit
Breaker Sizing Table” in the previous section to fi nd the appropriate circuit breaker or fuse for your motor. For motors requiring
a 60-amp breaker, the Minn Kota MKR-19 60-amp circuit breaker is recommended.
