Wiring up trolling motors

I have 2 12v minnkota motors… on on the bow and one on the transom. Both are 12v. I am thinking about wiring up 2 batteries to run them both. Thought is to run jumper positive to positive and neg to neg, then run a set of leads off one to the bow and off the other to the transom. Does this sound right? Any tips on how I should do it differently. My goal is to have the most use out of my electric motors in the day, without having to switch wires around. And some days I spend the majority of the time up front, others it’s in the back of the boat.

I currently have a 24v bow mount that crapped out on me. I am going to replace it with a 12v I don’t use the bow mount much. My 12v transom mount gets most of the use in the day. Last year I had it wired to its own battery and it would run low or out most days. I am thinking I will move that battery (New last fall) to replace the starting battery, which is 9 years old, as far as I can tell. This will eliminate one battery from the boat.

I have found that a bow mount pulls the boat more efficiently than a transom mount would push the boat. The battery would then last longer.
I would suggest getting a bow mount with a remote to fish from anywhere in the boat.

I’ve got both bow & stern 12V TM’s, hooked up to one battery. Each has it’s own circuit breaker, so I could run both at the same time, if needed, without popping the breaker.

If you want to go the 2-battery route, you could add a simple 1-2-1+2 battery switch, with the TM’s wired to the switch, that would allow you to quickly choose each battery, or both in parallel.

For a 12v motor you are correct. Pos to Pos. Neg to Neg. put a breaker in both pos wires out to your trolling motors. And use heavy enough wire. 6ga is about perfect. It will make your trolling motors more efficient which will give you more run time on your batteries.
