Outboard and trolling motor wiring question

[wlgorman]

I need some advice. I have a 24v trolling motor that I haven't used since 2 batteries were stolen out of my boat. I used to have 2 batteries wired in a series by themselves for the tm. With another by itself for the outboard and other electronics.

I attached a pic and I'm wondering if this wiring setup would work, if so that'd save me about 100 bucks for a 3rd battery. Thanks gs

I would not chance that my outboard would not start because I ran my trolling motor to long.

agreed. go with the third. trolling batteries tend not to crank as fast as cranking batteries anyway.
