In-Line Fuses for 24-Volt Trolling Motor

In-Line Fuses for 24-Volt Trolling Motor

In-line fuses protect your trolling motor from short-circuiting or overloading from excess electricity. For many boaters, they’re a non-negotiable feature; they need their equipment protected. There are many in-line fuses to choose from, but only a handful are worth trusting your gear with.

The best in-line fuse for a 24-volt trolling motor is the WindyNation ANL Fuse Holder + ANL Fuse. We prefer this type because it is easy to install, inspect the fuse, and quickly change a fuse. Additionally, you can connect multiple size wires (up to 2/0) using a 5/16 wire terminal, and the fuse holder supports up to 300-amp fuses.

In this article, we’ll also cover a list of the best in-line fuses for your 24-volt trolling motor, what you need to look for, and general information about using in-line fuses. Enjoy!

Overview of In-Line Fuses for 24-Volt Trolling Motor

An in-line fuse is a fuse in the circuit between a battery and a device. If you’re using a fuse for a trolling motor, it’s best to keep the fuse as close to the power source (the 24V battery bank) as possible.

You can use many fuses for a 24-volt trolling motor, including a bladed model, an ANL setup, and an AGU design. All of them have pros and cons, including ease of access, security, simple installation, durability, and more. Review our favorite products for inspiration.

What Size Should an In-Line Fuse Be for a 24-Volt Trolling Motor?

Choosing the correct amperage is crucial for your fuse to function properly and prevent an electrical fire in your boat. If the fuse is too small, it’ll cause circuit issues and randomly trip. If it’s too big, it won’t trip when there’s a power surge, making it virtually useless. According to DC Trolling Motor, a 24-volt trolling motor typically requires a 60-amp fuse.

When looking for a fuse and fuse holder for your setup, make sure they offer a 60-amp setup. Inspect your power source (the 24V battery, in this case) and the device (the motor) to determine which amperage you use.

Typically to determine your required fuse size, your need to consider the maximum amp draw of your motor and the maximum amp capacity of your wiring. If your wiring capacity is lower than your motor’s maximum amp draw, then you should upsize your wire. Bluesea systems have a wire size calculator at this link.

How Do You Install an In-Line Fuse?

Installing an in-line fuse is much easier than you might think. Below, you’ll find the step-by-step process:

  1. Disconnect the wires from the battery.
  2. Install fuse holder as close to your battery as possible and secure.
  3. Connect the positive wire from the trolling motor to one side of the fuse holder.
  4. Connect the wire from the battery’s positive terminal to the fuse holder.
  5. Insert fuse and tighten all connectors and covers.
  1. Give them a light tug to ensure they’re secure.
  2. Reconnect wires to the battery

These instructions are basic for most in-line fuse holders, but each has its unique way of connecting wires. You might require adding ring terminals, heavy-duty butt connectors, or solder and heat shrink for quality connections that will last.

We have more detailed instructions on our website. If you would like to see our easy-to-read schematic, use this link.

Why Are In-Line Fuses Necessary for 24V Batteries?

There are a few reasons for a fuse, but the most important reason is to guard against fire in your boat. The proper size fuse will prevent your wires from overheating or shut down the power from your battery in case a wire is damaged.

Additionally, without a fuse, you’ll risk an electrical surge. While it’s unlikely, it’s always important to protect your investment from these issues. If the power source overloads from the motor’s demand, it’ll short the battery or cause it to overheat. In-line fuses are designed to trip if the amperage gets too high. Instead of shorting the battery, it triggers the fuse, shutting everything off.

Why We Prefer in-line fuses over circuit breakers for our electric trolling motor

In-line fuses are a more affordable and durable option than circuit breakers for use with an electric trolling motor. They are easy to tell when they are bad – usually, the wire inside the fuse will be burned or melted in the area of the fuse.

In-line fuses are also cheap to replace. Circuit breakers, on the other hand, can be more expensive to replace, and they are not as easy to tell when they are bad.

A circuit breaker may trip for several reasons, including a surge in voltage or excessive current draw. Most fuses have a small delay before they trip, allowing them to handle startup surges better than circuit breakers.

Finally, because most circuit breaks work on a bimetal technology, after a breaker has tripped or even been in service for many uses, the metal will warp. The wrapped metal can cause the breaker to trip at lower amperage until the breaker is almost useless.

For these reasons, we recommend using fuses over circuit breakers for your 24-volt electric trolling motor system, or for that matter, 12-volt and 36-volt trolling motor systems.

Which Fuse Should You Choose?

You’ve likely seen the three best fuse types (check out our best fuses of each type below). If you’re having trouble choosing which one is best for your setup, consider the following tips:

  • Bladed fuses are very durable, best for effortless removal and installation but are challenging to inspect.
  • ANL fuses work to protect the current with a plate and have a start load delay, but the holder can be fragile.
  • AGU fuses are great for connecting without a terminal and showing what’s inside; however, some models contain spring or pressure-fitting metal tabs that should be inspected seasonally.

Each fuse style has pros and cons, so let’s dive into the list in the next section.
