Also remember that on most Minn Kota motors, Minn Kota requires 6 gauge and a 50 amp fuse/circuit breaker or the warranty is voided. Not sure what Motor Guides requires. I personally feel that the 8 gauge would work fine, but for the small amount of $$ that is involved versus a voided warranty, I went with 6 gauge.

If you need really flexible cable, pick up some 6 AWG or larger welding lead from your local welding supply house. They can also provide copper terminals to fit the battery posts and the TM leads. This stuff is very flexible and a little smaller for it's current rating due to the way it's built. Insulation is tough and will be rated higher than anything a fishing boat will have. This along with a 60 amp circuit breaker and you won't ever need to re-do it.

You have to look at it like this.Originally Posted by Fisherman_Wantabe
Not trying to start anything here. But Ohms law says the greater the voltage, the less the amps on the same load. So that means if 8 works on 12vdc it will also work for 24vdc unless you change the load.
12V on a 10 ohm load = 1.2 amps
24V on a 10 ohm load = 2.4 amps
Go with the larger gauge wire.

Don't have the time to get into motor formulas, but go look at any multi-voltage motor face plate and you will see the higher the voltage the lower the amps.

volts X amps = watts 12volts X 1amp = 12 watts
Use the biggest gauge you can and you'll lose less power to resistance from the wire.

That's what I did; worked well. One question: why couldn't you use a long heavy-duty set of battery jumper cables for trolling motor wiring?If you need really flexible cable, pick up some 6 AWG or larger welding lead from your local welding supply house.
