I seem to leak a little bit up under the driver and passenger dashboards and right where you walk to go up to the bow...I can't seem to find the leak and it isn't anything huge because I can be out on the lake for hours and all that happens is the carpet gets a little wet...any place I should look and what I should look for?? Also I am wanting to get the foam out from under the floor and possibly the bow this offseason and was wondering how the heck I get down there?? I have a 1971 Larson 16' Shark... There is a plywood piece then a fiberglass type material and under that complete hard foam.. I know this because parts of the fiberglass part is cracked and I have begun to remove it. The foam is rather hard and don't know the best way to get it out...I just completed a complete interior appolstering. I believe if I take that foam out I will find that its pretty waterlogged and i will help the performance of my boat a bit.
