Anyone have experience or know what the deal is with power degradation in regards to how long your power cables are for your trolling motor? I figure mine are run about 18 feet, and it seems like the t-motor just isn't as strong as it should be. I had the battery checked and it's fine. The motor also doesn't seem to have any kind of problem, it just seems like the power is kind of weak even with the battery freshly charged. The wire I'm using is sort of medium gague. The really heavy stuff was so expensive that I didn't get it, but it's not just some thin junk either. Any ideas on this?
