I made myself a short set of jumper cables, roughly 2 feet long with 6 gauge stranded wire and some clamps I bought from Lowes. Keep them in a zip lock bag in the boat. Three years ago, I was fooling with the cranking battery and I guess I shorted the positive without knowing it - blew the fuse in the motor housing. Apparently, I ran for a while solely on the cranking battery. After fishing a spot, wouldn't crank - stranded. Learned my lesson, now I know I can crank the motor from the trolling motor batteries if need be. I figure a safety precaution guys, thought I'd share.
