I just bought a Min Kota Trolling motor and I am trying to hookup it up? What is the best way to do so? Do I buy a new battery? Can I use my boat battery. If I buy new battery I would like it to charge of my motor. What do I need to do this? I am very frustrated with Minn Kota not sure if the motor is a 12 volt or 24 volt? Also my battery is located in the stern of the boat and the trolling motor is in the bow... The battery cable is not long enough, what do I do with this?? Help please.
