hey guys im hooking up my new trolling motor its a 55lb thrust minnkota edge bow mount. i was just wondering what the guage the wire is. i believ it is 8 guage but not sure. any help would be nice.

If you are wanting to know what gauge wire to run from battery to bow I would use at least 6 gauge.

This is dependent on a few factors.  I am going to give you the exact way to measure here.  This is directly from Minn Kota.  In short it depends on the length of the run, the amps from the motor and the loss of voltage.  Try this link for to get a better idea.

From the battery to the trolling motor plug, use the largest you can afford. The ideal situation is zero voltage loss due to wire length. Some is acceptable or tolerated, but keep it as low as you can. Most bass boats are rigged with 6 guage wire from the transom to the trolling motor plug at the bow.

My 2009 Bass Tracker was rigged with 8 gauge and I changed it to 6 gauge to improve the length to voltage drop ratio.

Agreed Wayne.  The larger the better.
