Trolling Motor Amp Draw, Circuit Breakers, Fuses, and Extending the Battery Leads

Due to the many variables when boating (including wind, waves, current, battery condition, etc.) we are unable to specify the amp draw at any speeds other than max power. The motor is only able to draw up to a specified amperage. You can reference the Conductor Gauge and Circuit Breaker Sizing Table below for the maximum amp draw for your motor.

Wire Gauge and Circuit Breaker/Inline Fuse Size

Trolling Motor Power Leads

  • Trolling motors come installed with 6 ft. 10 AWG red and black power leads. We recommend adhering to the chart below when selecting the correct gauge of wire to extend the trolling motor battery leads. Note: The Endura 30 lb. thrust motor has been optimized to perform as a portable trolling motor. We do not recommend altering the battery lead wires on this motor.

Circuit Breaker/Inline Fuse

When rigging your trolling motor, we recommend using a circuit breaker or an inline fuse connected to the positive battery terminal as close as possible to the battery / batteries

Circuit Breaker Example

NOTE: QUEST Motors are designed to not pull more than 60 amps on high speed. For Safety Circuit Breakers larger than 60 amps should not be used for QUEST Motor 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 qualified marine technician. The following specifications are for general guidelines only:
