Electrolysis

Using the main engine battery as a power source for the trolling motor may cause electrolysis on metallic parts. If the motor and
battery wiring are installed correctly and electrolysis issues continue, separate the trolling motor from any other boat
electronics. Using the main engine battery as a power source for the trolling motor is not recommended. Refer to Battery
Connection for correct installation.

Battery Connection

Before working around electrical system components, disconnect the battery cables from the battery to prevent injury or
damage to the electrical system due to an accidental short circuit.
Disconnecting or connecting the battery cables in the incorrect order can cause injury from electrical shock or can damage
the electrical system. Always disconnect the negative (‑) battery cable first and connect it last.
Failure to operate the trolling motor within the recommended voltage specifications can cause product damage. Do not
exceed the maximum supply voltage.
IMPORTANT: Refer to the decal on the head of the trolling motor to determine the voltage requirements of your trolling motor.
12‑Volt Battery Connection
1. Starting with the negative (–) lead, disconnect the battery cables from the engine starting battery.
2. Install a 50‑amp (good) or 60‑amp (best) manual reset circuit breaker in line with the trolling motor power cable positive (+)
lead and the trolling motor battery positive (+) terminal.
3. Connect the positive (+) trolling motor lead to the positive (+) trolling motor battery terminal.
4. Connect the negative (–) trolling motor lead to the negative (–) trolling motor battery terminal.
5. Connect a jumper cable (common ground bond) from the trolling motor battery negative (–) terminal to the engine battery
negative (–) terminal.
NOTE: Vessels using 12‑volt trolling motors with multiple batteries must have a common ground bonding circuit. Not
establishing a common ground between the vessel batteries may cause severe corrosion, electrolysis, or electrical shock.
NOTE: The common ground bond cable should be no more than one wire size (gauge) smaller than the battery cables, nor
smaller than 16‑gauge (AWG). The common ground bond cable must be insulated, and secured to the negative (–) battery
terminals with ring‑style connectors.
