The motor instructions say to use 6 gauge wire and a 50 amp fuse. Many sources have smaller wires in the tables as well.
In this case you need two 12v deep cycle batteries a battery connector cable and a trolling motor power cable.
Wire size for trolling motor. Overall there are 40 sizes from 0000 to 36 AWG. Interestingly the 0000 AWG wire is the thickest 046 or 11684 mm. The smallest 36 AWG one is 0005 or 0127 mm.
Many sources have smaller wires in the tables as well. Many beginners find it difficult to remember that a smaller number indicates a larger wire. The volts that your trolling motor uses will usually help you to determine the size of wire gauge and circuit breaker to use.
Most trolling motors for kayaks will be either 12 volt or 24 volt. With a 12 volt motor youll need one 12 volt battery. With a 24 volt motor you will need two 12 volt batteries.
In summary you can follow the steps below to determine the proper wire gauge for your motor. Step 1- Round up your maximum Amperage to the nearest 10. Step 2- Determine the total length of wire needed for the round trip and round up to the nearest 10 feet.
Step 3- Consult the table below to select your preferred wire gauge. Your kayaks trolling motor requires a circuit breaker rated 50 to 60 amp but it usually depends on the volts of your trolling motor and the amperage. Determining the Right Wire Size A large number of trolling motors use a wire gauge rated 8 but you should always consider the current of your trolling motor which usually changes the length of your cable.

Just keep in mind the amperage of the motor because that can change the wire size you will need. Shaft length is of key importance because choosing the incorrect length can cause your trolling motor to cavitate and lose thrust. To get the correct length if you have a transom trolling motor the general rule is that the top part of the motor should be submerged 12 inches in the water.
Trolling motor wire size. According to the Minn Kota web site specifications a 55 lb. Thrust motor has a miximum draw of either 43 amps or 50 amps depending on your model.
In any case we round up to the next even ten amps - 50 amps. You want to run 20 ft. Of wire in your boat and the maximum amp draw of the trolling motor is 37Amps.

In most cases the manufactures recommended wire is 8 gauge for most 24-volt systems and 6 gauge for a system of 20 feet or longer. To account for voltage-drop heat and current changes resulting from low batteries I recommend 6 gauge wire and 4 gauge for over 15 feet. Most trolling motors only come with power leads that are 3-5 feet in length.
You may need wire extensions to reach your battery setup. Consult your motor manufactures guide or ask a professional what wire gauge you will need depending on the length and your motors thrust. You can always splice a very short run of 6 or 8 gauge wire to your longer and lower gauge wire if you need to complete the connection to a new or existing plug and receptacle.
We always recommend using marine grade products and we also recommend using a butt splice with heat shrinking to join separate pieces of wire. The 20 ft boat will have 40 ft of wiring and it will drop 16 volts across all of the wiring at 40 amps. The 6 inch section will not make a significant difference if it is 6 gua or 10 gua.
The boat with 6-8 gua has plenty of capacity for the motor he is using. Be carefull when you get to the connectors.
