i would use 6 gauge. you might get by with 8 but i would not go any smaller than that. you can get 6 gauge stranded THHN at lowe's. i just bought some last week for a boat i am working on. i bought 3 strands for a 24 volt system .3 pieces 25 ft long was $45. so you should be able to get 2 strands for $30 or so. some people say you can use 10 gauge because that is what most trolling motors are wired with. but remember that is a very short run of wire. the long the run the larger you should go. i hope this helps. if you have any questions just pm me. i have wired probably hundreds of trolling motors through the years and rewired close to that many boats.

Thanks for the info. My boat is a 16' hydrasport BB, one battery 12V system, located in the back by the motor. I currently have a minnkota 33lbs thrust tm and I just want to be sure I have the right size wire for the new one.
Thanks,

Technically, 8 would be fine on a 12V for only 16'. However, the cost difference in the 6 is insignificant if you had to tear it out and redo for 24V later. Go with the 6.

also add a 50amp breaker at the Battery

true there is a big difference but the thhn from lowe's will work just fine. i have used it for years. it is not as soft but once you get it in the hull and connected it works just fine.

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.

Go with 6 and forget about it.
