Cro, check out the Venture rigid pontoons, I'll put the link below. They can be outfitted with a battery/motor plate for a trolling motor. Also if you can find one there is a Float Power station where the battery and motor fit in a separate smaller float tube you tow along with the pontoon. I'll add a couple pics of mine on here for ya!
