I am looking to replace the wood floor on my 81 and am wondering what thickness marine ply wood to get? How many sheets? And how much resin to put on the floor?

1/2" and you can do it with 2 sheets if you lay it out very carefully. Be sure to seal the underside with glass/resin or saturate with epoxy or at least a couple coats of good paint, before installing and it'll last a whole lot longer.

Figure on 1-1.5 gallons of resin if you're using 1/2oz mat or cloth. You want to use as little resin as possible and still wet out the mat. Excessive resin will crack and let water through. Thinning the resin with a bit of solvent (acetone) helps it penetrate into the wood. You want to use laminating resin if you're doing more than one layer or layup. It remains tacky when exposed to air helping the next layer bond. The final layer (or gelcoat) should be finishing resin or have wax added to seal the surface so it fully cures.
