You want to spend the day fishing, but your motor is too loud. You won’t be able to catch any fish driving your boat around because they will all get scared away. You need a trolling motor to move your boat around quietly.

Before buying a trolling motor, you need to understand a few things like how trolling motors work and what trolling motor wire size you need.

How Do Trolling Motors Work?

A trolling motor can work well in freshwater and saltwater. You can place it on the boat in three different areas. These places are the bow, transform, and the actual motor.

A trolling motor uses electromagnetic acceptance to work. Sometimes they work slower than a regular motor, but many places now offer powerful trolling motors. This means you can get a trolling motor for a small or large boat.

There are different kinds of trolling motors to choose from. For example, you could benefit from getting one of the lightweight electric trolling motors.

Every motor has a thrust, control, shaft, propeller, motor, and motor. This is no different for a trolling motor. The trolling motor wire size you need will depend on the battery size and other things.


For your trolling motor, you will want to have a deep cycle battery. These batteries control gadgets in a way that allows them to be completely energized without hurting the battery.

The battery you choose will depend only on the voltage of the trolling motor. There are three kinds of batteries you could use: 12 volts, 24 volts, and 36 volts. It’s important to know what battery size you have before buying trolling motor wires.

Twelve volts are normally used for kayaks. Bigger boats will need 24v and 36v batteries.

When trying to figure out a trolling motor wire size, you also need to consider the voltage and amps of your motor. This can make it easier to find the right battery size for you.


The amperage on the trolling motor refers to how much power or current it draws from the battery. The amps that are drawn can help determine the size of the circuit breaker you need for the whole system.

To figure out how many amps your motor draws, you can look at the pound thrust rating of the trolling motor. This number can be calculated by dividing the pound thrust by the voltage and multiplying that number by 12.


Volts are also helpful when trying to determine the size of the wire gauge you will need to use for your trolling motor. A 12-volt motor will need only one 12-volt battery. For bigger boats that have a 24-volt motor, you have to have two 12 volt batteries.

The voltage refers to the current that is flowing from the battery to the motor. Generally, this is called direct current because the current is flowing directly from the battery to the motor. You also need to consider the type of breaker you have or want to use.


A circuit breaker works to protect the electrical circuit from any damage, especially if there is an overload of current. If the current level gets too high, the circuit breaker will stop the power automatically.

You need to consider a circuit breaker for your trolling motor because most US Coast Gaurd regulations say that you must have a circuit breaker installed. This is for the safety and protection of any ungrounded current conductor.

The general rule of a circuit breaker is that it needs to have a higher amperage rating than the motor. This allows it to be able to handle any level of current that gets passed through it.

A kayak trolling motor usually requires a 50 amp or 60 amp circuit breaker. This will depend on the amperage draw and voltage of the motor.

Wire Gauge

A wire gauge or AWG (American Wire Gauge) refers to the area of the cross-section of a round wire. A larger wire will have a smaller AWG number. If you have a longer wire, you’ll need a lower AWG length to make up for the extra length.

What Trolling Motor Motor Wire Size Do I Need?

When it comes to the trolling motor wire size, there is a lot you need to consider. However, a lot of trolling motors can be used with an 8-gauge wire. Just keep in mind the amperage of the motor because that can change the wire size you will need.

The trolling motor manufacturer should tell you the ideal trolling motor wire size you need. A trolling motor wire chart can also help you make a decision.

The most important thing to remember is that the AWG rating of the wire can change depending on the length of wire that you need. If you have a powerful motor, you will most likely need a thick wire that has a lower gauge. Don’t forget that the size of the circuit breaker has to be enough to handle the amps of your trolling motor.

How to Wire Trolling Motors

Once you have the right length wire for your trolling motor, you need to know how to install it. The first thing you should always consider is safety.

Simply put, to wire trolling motors, you need to attach the connector kit to the battery and then attach the motor cables to the connector cables. It can be a difficult concept to grasp but can be easily done with the right tools.

Trolling Motor Wire Size Explained

Now that you have an understanding of all of the things you need to consider when choosing the trolling motor wire size, you can get the right one for your boat. Enjoy boating smoothly on the water and catching a lot of fish because of your quiet trolling motor.
