Bedding Aluminum?

I was looking at the ranger boats site, and they have alot of videos of them constructing a ranger, from gelcoat to lamination to putting the deck and hull together. When they install the transom, it looks as if it is constructed of aluminum plate and fiberglass panels bolted together. I like the idea of having a piece of 3/8" aluminum with bracing that is fiberglassed to the stinger and tied to a bulkhead. Does epoxy and glass readily stick to aluminum? I just feel that if I bolt a heavy motor to a plywood composite or even a foam cored layup, that I may stress the transom and have cracks everywhere. I would feel alot more comfortable in tourqing down mounting bolts if knew I had some thick metal to bolt it to. The motor would spread the load onto the transom and the plate on the inside would spread the load alot further than would 4 washers. Any thoughts?

5200 will bond the aluminum. I have delaminated fiberglass removing metal fittings from junk boats.
