I bought one of these used...in the 90's. Great boat to slide in and out of the back of the truck and hit all the small TM only lakes around. Didn't do much to mine however...didn't want to add a lot of weight. If you have your's on a trailer...that may be a different story. About the only thing I did was replace the flimsy plastic top side on the front and back with some 3/4 treated plywood, covered in carpet, and also made a bunch of 1x2 " cedar treads I screwed into the aluminum bracing tubes all along the floor to walk on. Since I didn't buy the boat new...not sure about the original seating and what the previous owner did...however I've changed mine a couple of times to get the height right for me. I've put way more fish in the freezer with that boat over the years than my big boat. It is also nice to fish in the quiet of a TM only lake. No water skiers running over your line, LOL.
