Re: wire size ???

How far are the runs? and what kind of amps are you drawing? http://www.amazon.com/Boatowners-Me...=sr_1_1?ie=UTF8&s=books&qid=1252002460&sr=8-1

Re: wire size ???

Key factor missing -- what is the current draw of the trolling motor? 30 amps, 40 amps, 50 amps -- what? Tell us make model and thrust and we can give you an approximation but all we know is that it's a 12 volt motor. In most cases, 10 gauge would be fine for the accessories. At that distance it is probably not heavy enough wire for the trolling motor.
