Not know what engine you have, trolling motor size, and how far away the batteries are, makes a difference. I'll offer this for starts until you can provide more info

Use 10 AWG for feeds to your switch panel, 14 AWG for everything except trolling motor. For the trolling motor, if I knew what model it could be looked up. Search for your manufacture (Minn kota) then go to the web site and find where they instruct how to find.
Here is Minn kota site http://www.minnkotamotors.com/Support/Battery-Selection---Rigging/
