I got lost at volts dropped per foot and amps and blah blah blah. Joe i have wire dozens of trolling motors over my 25+ years of bass fishing. Then put a jumper at the batteries for a 24V trolling motor. I'm more just curious about that. That's about the same as the difference in capacity between a group 27 and group 29 battery. Look at your fuse panel at home. Somebody had confused the crap out of me with all that fancy voltage talk and voltage related to rpm stuff.
Another words, the 10% or so voltage losses in trolling motor wiring become objectionable to us well before safety is compromised with possible overheating. Then, go to the trolling motor connector, and measure again. The cranking battery is completely seperate. Two wires can be used for 12, 24, 36, 48 or any other opeating voltage. I'm sure typing this out is confusing so is there anyone you all would recommend that works on electrical that I could speak with boat shops? This breaker will pop in the case of a short - and that is what you are protecting against.
Two 12 volt batteries are required. Too much spray over a couple of years caused it to fail. A 50 amp will even cause problems with the 71 pound as the batteries age or start getting weak. Would it go to the positive terminal of the other battery and if so, why? Orient the batteries in the boat as such and wire as such. Connect the two reds in the front of the boat to the Pos + terminal of a bus bar 6. That extra wire on the positive terminal that is the system positive for 24 volts is the confusing part. Once the wires were through, I connected them to the plug.
Measure, with a voltmeter - the voltage that is going into the two ends of the wires going to the front of the boat for the trolling motor. My boat had another set of wires already run to the back with inline fuses for 12-24 volt systems. It sounds like based on that, my 10 ga wire could carry 35 amps safely at 24V. It is certainly not my intention to upset anyone here or try to insult anyones intelligence, I can see I am having issues in trying to get my point across, and that is no ones fault but my own, my apologies. These are specs from MinnKota, not numbers pulled from the air. How low of voltage can a trolling motor be safely run at? Fall is around the corner and I need to get the trolling motor hooked up so I can chase birds and troll the bayous.
Safety overheating is not really an issue in the ranges being considered. That should extend the life of my wires significantly and can prevent a fire hazard. Chances are it has many more slots for fuses or breakers than are actually being used. He has not said what year model and type boat but six gauge cable has pretty much been the standard for year of any size, some have even installed four gauge. One of the best upgrades to small fishing boats is replacing the 12-volt trolling motor with a more powerful 24-volt model. It has be a while since I looked them up and I'm sure someone with come back with the right numbers just to say I'm wrong, but I think it's something like this: A 12 volt motor using 1.
Connect the trolling motor Pos + to the Pos + of your bus bar 8. I am just as much at fault here, I want to be perfectly clear, I have already offered my apologies. That is done with an extremely low current draw of 5 to 6 amps and when you increase the amp load, the battery Ah rating drops a lot. I'm hoping there is a way I can use the existing set up as I mentioned and just add another battery in series as in the diagram. What you're saying is exactly what I expected.

If installing a leadwire plug, observe proper polarity. This avoids a potential problem of applying 24 volts to 12 volt accessories because of an accidental grounding issue. In addition to producing more thrust, this upgrade will also let you spend more time on the water, as the combination of two trolling motor batteries will last much longer before charging is required. Can I safely get by running a 36 volt trolling motor over the existing 10 guage or would I be a wiser man to run something heavier 4, 6, or 8 to the back of the boat some 20' feet away from the bow where the batteries are stored? If you do not see your area listed, please be sure to and let us know how and where we can find the lake levels and crappie fishing reports so we can get them posted for you! Let's get some terminology stright first. You maybe confusing your cranking battery wiring or trying to combine the cranking battery with the trolling motor battery circuit.
For your safety if you aren't sure about the connections, do this. One of the most common problems is a loose connection on a battery terminal, so always check that first. Start by disconnecting all of the wires from you trolling batteries and Trolling motor. It's not just a random wire that somebody put on I'm the 2nd owner, but the first owner barely used the boat and I don't think he messed with it. I don't have the figures or done the math but I seriously doubt there is very little difference in the current draw between the two motors. The recepticle and plug are 3 terminal and I think the red 24V , black ground , and orange 12V go there.
