Hi

Looking to run some new electronics, trolling motor wires and wondering if I should be using marine grade wire or can I just use the wire from home depot?

Is west marine the only place to get marine grade wire in DFW? Any help is much appreciated.

The factory wiring for my trolling motor is copper based wire. Corrosion is an issue with copper based wire but I haven't noticed an issue yet.

Marine grade will prevent that issue but is it really an issue? IDK

marine wire is tinned copper and will resist corrosion. If you run in saltwater, you probly want that. I used automotive, after 10 years or so, it gets a little discolored at the ends but I'm satisfied with it. Your results may vary.

Got it. I guess I'll go with marine since I'm re-doing them anyway.

Do you know if using the Minn Kota 60 amp breaker will I need to use two of those in a 36v configuration on an Ultrex 112? I don't know if those breakers hook up using only one wire or two wires at a time.

they hook up positive side from battery to positive side going to trolling motor.

I use welding cable (for trolling motor), I run in saltwater all the time. My battery lug connectors are tinned and I used waterproof shrink wrap. I use a Marinco connector for the trolling motor and I spray fluid film over the connection. Never had a problem in over 5 years.

Remember you want high strand count (more the better) and pure copper for trolling motor. That's why I use welding cable, you can get it cheap on Amazon. For small stuff lights, pumps, etc I used the stuff from Lowes in 50ft spools, the pliable wire, like the wire on your trailer lights.

FYI: Current flow(amperage) doesn't travel thru the middle of wire strands. The electrons travel on the O.D. of each strand. Sometimes you get corrosion a few inches up inside an insulated battery cable. There's nothing wrong with the wire strands, but they're corroded on the o.d.'s and current won't flow. If you are using wire in a saltwater environment, or near bilgewater, it's very worthwhile to pay the premium for Marine(tinned) wire or cable.

It's hard to find, costs more, but not having to pay a TowBoat charge($$$$$), probably is worth it. Not to mention the grief and anguish. YMMV IslandJim

Check that. I believe from my decades old electronics reading that DC current runs equally throughout the wire, AC current flows mostly on the outside, called skin effect. Has to do with magnetism of the opposing fields. But I am an old. Memory fades with age.


I don't believe you will get any better results with marine wire unless you take it in salt water.
