If you can bring your boat to shagawa which is close my friends up there are doing very well on eyes lots of small ones but pletty of eaters. Burntside is a not the easiest walleye lake but it is a night bite. If you like pout you can get some all summer long there. I like to fish near the little finger bays that have mud bottoms.
I would be cautious about removing seats and decks as they are usually part of the integral strength of the boat . If you remove anything make sure you add brackets or such to help keep the boat strength intact . For example bench seats that run the entire width of the boat are attached to the floor and both sides and help to strengthen the boat, if they are removed the sides of the boat are weakened, your modification should include a way to compensate .
