Just got a new to me 2001 G3 pf175. It is currently set up for a 12 volt trolling motor.

I thought I had seen a discussion on trolling motor battery setups but can't find it now. I seem to recall it mentioned guys using a golf cart battery and getting more run time than a regular deep cycle.

I want to be able to start spider rigging or pulling cranks once I get set up for that in the future
I will also likey be going to a 24 volt system once i find a deal on a used motor.

Thoughts advice and recommendations or links to other discussions are appreciated.
