I have a 14' jon boat and am thinking about doing a conversion on it like I've seen on YouTube where plywood and 2x4 are used. I realize this makes it heavier so would that stabilize the boat so that it doesn't rock so much? Also, right now I have an electric motor so would the added weight be too much for an electric motor? I have also considered using PVC pipe on the sides to stabilize it. Your input would be appreciated since this is my first boat.
