Snagged this on eBay, my original gauge was 0 to 60 x 100and this one is 4 to 70 x100. I think it will work. Comments?

I did a similar repair on mine. see link to that thread:
http://www.mastercraft.com/teamtalk/...ad.php?t=51871

I edge-glued a couple of pieces of pressure treated s.y.pine, then just used a regular polyester resin over it (with black colorant). Sawed and cut down the edges of the wood so that it wasn't any thicker than the fiberglass shell edges. Reinforced the long edge with an aluminum angle, with one leg cut down. This was used to reinforce the hinge locations which are bolted through the angle. Sorry I don't have any photos (other than in the link above) as they were on the previous computer that got some ransomware crud on it.
After I got the wood fitted fairly well to the shell, I poured some more resin between the shell and wood to solidify it. So far it has worked well, very solid. Good luck with it.

I thought about using Trex composite deck boards and laying them in the fiberglass. Fill it all with resin and then glass over the top. I have a few of these lying around from a deck build.

Thankfully, I have not had any flooring issues! Damn!

The only issues I had were the gunwales had started disintegrating along with fasteners holding them in place.

Thanks for posting pics of the switches. I may be in need of those pretty soon!

Great progress! Keep those pics coming!

Only a matter of time!!!! Some of my floors felt solid until I pealed the fiberglass backing off.

I agree that 3/4" is overkill. Since the floor panels aren't structural I don't think marine plywood offers any benefit. If it's fully encapsulated in resin rot won't be a problem either. You could go to your local store and pick up whatever thickness serves your purpose.

I picked up a sheet of 1/2 marine grade plywood for my floors ( $70 bucks man..) Does fiberglass resin have a shelf life? My father in law owns a Ace Hardware and he has a bunch of fiber and resin that is older and he is going to give it to me for free.

Typically epoxy resin does not have a shelf life per se'. Most people in the business will throw out a "10 year" number but the contention is that is does not have a shelf life (resin). Caveat is this: depends on make and quality of the product. I have seen hardener set up within six months but there again, it is a store bought off the shelf tube or squeeze bottle that is measured for distribution in drops. Merely a part of the resin mix.

I use the epoxy based resin (100% waterproof) and an accompanying medium cure hardener. I have never had a problem with any type of shelf life over the course of a few years of use. Don't let it freeze; however if it does, it will re-liquify with warmer temps.

Polyester resin may be another story of which I am not familiar. I do know it is not 100% waterproof and may have a different composition. I defer you to the manufacturer's instructions on the label. I recommend epoxy resin for waterproofing flooring and wooden stringers.

I do not see any need for marine board when coating with epoxy resin (and vise versa). I use builder grade ply board and epoxy resin. Do not use builder pressure treated wood impregnated with Copper Azole.

1/2" thick is fine.

Ambient temperature has a distinct effect on the curing process.
