Hey Guys,

I'm in the process of replacing the floor on my center console and with the floor out have easy access to do any wiring, bilge work, etc.

I'm thinking ahead abit, but would like to install a 24V MinnKota Maxxum 70lb thrust on the bow. I have heard it is better to mount both deep cycle batteries as far toward the stern of the boat as possible as this will minimize the pounding they will take at cruising speed. The question is: I do have room up in the front (bow storage area) to mount them and thus minimizing the length of wire from the trolling motor to the battery. Which is the better way to go?

If mounting in the stern area (more specifically, both batteries would probably mount under the center console) what gauge stranded wire should I use? The run would be about 8-10 ft.

Also, Once i hook up both deep cycle batteries as 24V, is there any way to hook up a 12V accessory (horn, raw water wash down pump, etc) to one of those batteries or do I need to dedicate a 3rd battery to these.

Thanks!

I prefer mounting the batteries as close as possible to the motor to aviod voltage drop common in dc applications. You have the potential under load to require more energy the further your motor is from the battery. Heavier gauge wires are required the further you go.
