When you say the battery checks out fine. What does that mean? How did you test it? The standard marine starting battery cold cranking test or car starting battery cold cranking test will not show a loss of capacity on a trolling motor type battery.

The November Muskies Inc issue will have an article on this subject (Batteries, etc).

Subject: trolling motor wire

Hi Todd- My first guess is that you've probably solved the problem. I just calculated the voltage drop of #10 wire for a 25 ft circuit with a 50 amp load(Large trolling motor@ full power)at about 3.25 volts. That means your troller is only getting 9.45V when the battery is fully charged at 12.7V and that ~163 watts of power was being lost in the wiring.. The #4 gauge wire should definitely solve any voltage drop problem (to much wire resistance). The #4 calculates to .8V drop at 50A load and about 40 watts of power loss in the new wiring. If that has'nt solved it, then it's the battery or the trolling motor itself.
