    What size Optimas, and was whoever checked them familiar with the unusual voltage of Optimas?

    Trolling motors don't consistently go bad after 3hrs of use. I would say the batteries capacity is not as much as it once was. Means a bad battery. Next time you go fishing, check each battery with a voltmeter. After being out for 3hrs and trolling motor gets weak, check each battery again. I'm guessing you will have one that is substantially less.

    Group 34 Optimas are tiny batteries. 100 minute RC. Wouldn’t hard to run them down if you use the motor much.
