We had made one out of stainless. We cut a peice of stainless plate to the length and width we needed and drilled four holes in it to match the mounting holes on the trolling motor bracket. Then you drill four holes through the front of the deck where you want it to mount. Then weld nuts on the bottom of the plate. Mix you up some marine tech epoxy and cover the flat side of the plate and get a small buddy to crawl underneith the deck to stick it on. While the epoxy is still wet put the trolling bracket on and tighten it up to hold the stainless plate in place while the epoxy dries. Once it dries we drilled one hole in the middle of were the plate is and put a tapered headed bolt in it so it was flush with the top layer of gel and put a big washer, lock washer, and lock nut on the bottom. When its all done all you have on the deck when you remove the trolling motor is four small holes and the head of a stainless phillips head bolt that is flush. Plus it is very strong. We cut a peice of rubber i think a old truck bed mat and epoxed it to the bottom of the trolling motor bracket. That way the trolling motor bracket wouldnt sratch the boat. It was a little work but it was the cleanest that I have ever seen.
