well i suggested 6 gauge wire because of a couple of reasons. 1 years ago a friend that owns a trolling motor repair shop suggested it to me. he said you get less voltage drop. when you get less voltage drop your wires do not get as hot so you dont trip your breaker. 2 my uncle is a retired union electrician (30 years) and my brother has been a union electrician for 18 years. both swear that it is worth the cost . my uncle has 2 bass boats, my brother has 1 , my dad has 1, i have 2 all have been rewired with 6 gauge wire. we never have a problem with any of them. i have fished in several new boats or nearly new, that have problems with the wiring from the factory. remember the factory is trying to make things as cheaply as possible to make profit. i am suggesting you wire yours with a little over kill to save you head aches on the water. the few dollars you save now may haunt you later at the worst time on the water. just look at it this way. you spend money on a boat , trailer, motor ,trolling motor, batteries, rods reels, jigs, minnows, and what ever else you think you need to catch fish. why not make a one time investment in the peace of mind. so you wont have to worry about wiring issues in the future. thats just my opinion, but its your money and your boat you should do what ever will make you happy. you only live once. good luck and good fishing
