    Default BRM, got a question for you


    what size wire does express and others run from the back to the trolling motor. do they have a standard or does it depend on the customers needs or the t.m. that is gonna be used. reason i ask i am re-doing my set up and installing a pdv2 55. i called minnkota and the guy told be whatever size come out of the trolling motor, in my case 10 guage, they recommend a size larger coming from the battery. something about line drop, greek to me. since my travel is only about 6 feet he told be 10 gauge would do but use 8 if i could find it..could not find 8 gauge so i am using 10.

    Use 6. That way if you ever do upgrade to a 24v there won't be an issue.

    When it comes to wireing.....bigger is always better. Most boats use 8 guage but 6 guage would be even better.

    8 will work fine on shorter boats. I put 6 in the new 20'er. I have used 8 in every boat I've owned 18' and shorter without one single problem.

    BTW, use a good quality wire. I prefer the oxygen free copper wire (limber like good booster cables) because the oxygen in the copper causes more resistance. The resistance eats up your amperage to the appliance (TM). I use stuff like the auto stereo type for this reason, plus it's more multi stranded.
