On this river my trolling motor gets beat up. we fish so shallow and there are logs and cypress knees everywhere. I feel like my Ghost isn't as strong as it once was even with new batteries. I don't hear any noises but could I have weakened it internally ? Like gears or something? I am also wondering if that's why I had to replace batteries after 2 1/2 years. Could be draining the batteries. Is there anyway of knowing by symptoms or is it something that has to be looked at?
