I think it would be a great tender with cc ,but you would have some work and money ahead of you. Do you have a motor big enough or would you have to buy one, trailer looks a little dinky for it also. If it is a built like tank(weight?) plus mods and gear could add up pound wise for the trailer. Transom, I would guess it is for long shaft bet the transom just has highside around it? If your just looking for a jon boat/blind/motor combo there are bunches for sale on craigslist. I don't know what your hunting conditions are or where you hunt. Oh, and although it may seem like tank, I'd want to float it to make sure it don't leak like a seive. All in all it would be a fun boat build but questions I'd ask myself.
