Epoxy filled out with micro balloons
Put a new transom in my Trimaran yesterday. ( project almost done!)
Mixture of fr 251 and micro balloons mixed up to cake icing consistency. Apply with notched trowel . This stuff sticks like shit to a blanket !
You will want to fillet sides of box to floor and apply woven mat tape to bond box to deck. Good old YouTube will help you for that one.
Fibreglass and resin sales in Welshpool will help you out. What those ladies don't know about fibreglassing is worth learning. Very, very switched on with their trade.
Any problems let me know , glad to share knowledge...:)

I use this Product for small jobs- You can buy it from Welshpool. Six10 Thickened Epoxy Adhesive.

West System says Six10 adhesive provides similar characteristics to 105 resin and hardener thickened with 403 Microfibre Blend, but with the advantage of being pre-mixed and applied straight from the cartridge for point-and-shoot convenience with any standard caulking gun. They say it is ideal for stitch-and-glue boat construction, fibreglass laminate repair and general bonding, and it bonds to a wide range of materials including wood, metals, composites and masonry.
How It Works
A unique piston inside the cartridge simultaneously dispenses the resin and hardener from the separate chambers and accurately controls the ratio. The resin and hardener are separated from contacting each other until they are outside the cartridge.
It should be noted when doing smaller jobs, you don't have to use the static mixer. Simply squeeze out the amount needed onto a piece of plywood or board, mix the resin and hardener together thoroughly, and then apply to the job with a mixing stick or plastic spreader.
The hardener provides a long open time but has fast through-cure. Six10 stays workable in the static mixer for 42 minutes at 25°C , making it practical for long or complicated assemblies, and cures in temperatures as low as 10°C. It cures to a solid state in 5 – 6 hours at 25 degrees Celsius and will take high loads in 24 hours.
The coaxial cartridge contains 190ml of resin and hardener and additional static mixers are available in packs of 2.

Resin
Mixed with cabosil ( think that's what it's called). Looks like talcum powder. Mix in paint bucket with drill and paint mixer. Make it nice and thick. Good thing about it lasts for ages in bucked with lid on .Take out what you require add hardener put box on top . Sticks brilliant no screws nails nothing. Also really good for fixing chips under hull ect. Once stuck down and dry then use a little matting to neaten up. Easy as. Strong as.

I used this cabosil mixed
I used this cabosil mixed with polyester resin just recently and it is a VERY good glue for polyester glass to glass. I could see it working well on glass to timber too but I believe expoxy resin with a micro-balloon thickener would be the best glue.

No it's not expensive, I
No it's not expensive, I bought it from kirkside in Ozy park. It was about $10 from memory for the smallest jar they had. It goes a long way. It's awsesom stuff. You just mix it into you resin mix and get it as thick as you want. It turns the resin into a thick jelly form which you can apply with a putty knife or scraper or what ever. It's really good for filling holes in glasswork like old bolt holes... Good to have on hand if you already have some resin and hardener. You obviously need to key any flat surfaces like any other adhesive. 80 grid on glass would be good.

Glue
Don't be tempted to use polyester to try and glue to plywood. Polyester is excellent and bonding to more polyester but is no good at bonding to wood. Don't confuse what I am saying with encapsulated plywood like would be found in boat stringers/floors a they are totally encapsulated and therefore still bonding to other polyester.
As mentioned, epoxy is your best bet for bonding plywood to fibreglass. Make sure all the surfaces have a key to ensure a good bond. The west systems Six10 is a very good product and I have used it before with no dramas. If you aren't already set up with mixing cups, cabosil, resin, hardener, application tools etc then price of the Six10 seems like good value for money.
