I need to add some weight to the front of my new 1648 flat bottom jon boat. I am going to add a few pieces of thick plywood to the front deck to make it flush with the top of the boat. That will add some good weight without going overboard. Plus it will make the deck a bit stronger and more stable to walk on. My question is will liquid nails work to stick the plywood to the aluminum? Plus I would like to know what the best screws are at like home depot or lowes to secure the plywood to the aluminum? Plus I'm putting a nice thick plywood floor in it with carpet to add a bit more weight to the front of the boat. Probably 3/4 inch in the front and back. I just want to keep this boat basic and leave all the fishing room as possible for comfort. I may down the line mod it out. I just want to get this boat ready to fish. I have a brand new 25hp efi suzuki so power to push this boat won't be an issue. There is just so much weight in the rear and I need to counter weight it to balance it out and a nice thick plywood deck should do a nice job to add decent weight without going overboard like I said. Also what is the best thing to use to seal the wood to waterproof it but will still let the glue work with no issues? Thanks for any help.
