What Size Wire For 24 Volt Trolling Motor

So, there I was, out on the lake, sun beating down, fish jumping, and my 24-volt trolling motor just purring like a contented cat. But then, disaster struck. The motor started making a weird noise, like a distant, metallic protest. I looked down, and there it was - the wire, as thin as a whisper, glowing like it was about to burst into flames. I thought to myself, "Well, that's not supposed to happen." And that, my friends, is how I learned the hard way about choosing the right wire size for your 24-volt trolling motor.

Why Wire Size Matters

Let's rewind a bit. You might be wondering, "Why does wire size even matter?" Well, imagine you're trying to suck up a milkshake with a straw that's too small. It's gonna take forever, right? And if you try to force it, the straw might even collapse. The same goes for your trolling motor. If the wire's too small, it can't carry enough current to power your motor properly. And if you try to push it too hard, well, that's when you get a wire that's hotter than a summer's day on the lake.

So, what's the magic number? The American Wire Gauge (AWG) system is what we're looking at here. For a 24-volt trolling motor, you're typically looking at wires between 8 AWG and 10 AWG. But let's dive a little deeper.

Power and Current

First things first, you need to know how much power your trolling motor is pushing. Most 24-volt motors are around 30 to 55 pounds of thrust. The more thrust, the more power, and the more current your motor's gonna draw. A good rule of thumb is that a 30-pound thrust motor might draw around 30 amps, while a 55-pound thrust motor could draw up to 55 amps.

Now, here's where the wire size comes in. The thicker the wire, the more current it can carry. So, if you've got a motor that's drawing 55 amps, you're gonna want a wire that can handle that kind of current. That's where our 8 AWG and 10 AWG wires come in.

Length Matters Too

But wait, there's more! Wire size isn't the only thing that matters. The length of your wire can also affect how much current it can carry. The longer the wire, the more resistance it has, and the less current it can carry. So, if you're running a long wire from your batteries to your motor, you might need to go with a thicker gauge to make sure you're getting enough current.

And while we're talking about length, let's not forget about voltage drop. If your wire's too long, you might end up with a voltage drop that's big enough to make your motor run poorly, or not at all. So, keep your wires as short as you can, and if you can't, make sure you're using a wire that's thick enough to handle the distance.

Safety First

Alright, so we've talked about power and current and length, but let's not forget about safety. If you're running a thick wire, you're gonna need bigger connectors and terminals to match. And if you're not careful, you could end up with a connection that's not secure, or even worse, a short circuit. So, make sure you're using the right connectors, and that they're properly secured.

And while we're on the subject of safety, let's talk about heat. If your wire's getting hot, that's a sign that it's not carrying enough current, or that there's a problem with your connection. So, keep an eye on your wires, and if you see any heat, or any other signs of trouble, don't ignore it.

So, What's the Bottom Line?

Alright, so let's wrap this up. For a 24-volt trolling motor, you're typically looking at wires between 8 AWG and 10 AWG. But remember, the right wire size depends on your motor's power, the length of your wire, and a whole bunch of other factors. So, do your homework, and don't be afraid to ask for help if you need it.

And hey, if you're ever out on the lake, and you see a guy with a wire that's glowing like a candle, that's probably just me, learning the hard way. Again.
