I am in the middle of replaceing the transom on my 1974 16 foot baja speedboat. i am asccessing it from the inside of the boat. i have removed the fiberglas from the outside and now im working on chipping out all of the rotten wood. For that, I am now using the back end of a hammer and its taking forever. are there any other tools i can use to make it go faster.<br /><br />I also noticed i was cutting away a small part of the floor to acess the bottem of te transom that the wood was a little wet. so i cut out a bigger section of wood (about a foot back) and cut the fiberglas off the top of more of the wood to let it dry. I noticed that under my narrow floor that there was only 1 stringer running along the center of the boat and that the floor and stringer are glassed together. i poker the end of the stringer with a screwdriver and my fingernail and could make a small indentation. I am wondering if the floor is structural to the boat because it is only about 2 feet wide and the seats are not mopunted on it. also, is the stringers only job to hold up the floor or is it structural? Thanks
