Here is my polar kraft boat that i am going to try and modify. I cut the back panel out and found there to be styrofoam that was mainly rotten. I would like to put a livewell in here and on the other side put my gas tank. Do you think the boat will be alright without the styrofoam or should i add some back in and help or suggestion on the modification would be appreciated. ALso wanted to say that this is a great site glad to beable to post. thanks
