I picked up an 81 formula one last year ($100 to hard to pass up) with a running mercury 115 2 stroke with a bunch of extras, power trim, new custom prop, etc etc. it needs the transom and stringers redone. I started looking at it again today, cleaned out all the leaves and such,ripped into it/ cut the floor and pulled the upper hull off. after that i took some measurements and came inside. I came up with 8 sheets for stringers and other under floor pieces. I noticed in one of the videos in the thread linked to, his stringers are 1/2 the ones currently in the formula are 3/4, will 1/2 suffice or should I spend the extra cash for 3/4? Is there anything in that thread that maybe can be made better or done differently? Thanks all for any help.
