I'm setting up a Saltwater fishing Kayak. I recently purchased a FeelFree 13.5 Lure and done a few upgrades and one of the up coming one is a motor. I was thinking on going with a 2.5 Suzuki Outboard 4 stroke side mount with a Minn Kota on the opposit side or a transom mount trolling motor. Well this is my dilemma, I need some one that uses a transom mount trolling motor to tell me how much running time can you get out of battery and if is consistent. Of course it all depends on the weight and water conditions obviously.
