Epoxy paint over exterior plywood will last just make sure it is exterior

Put 2 coats of Min-Wax Urethane Spar Varnish on it (from Home Depot) and it will out-last you.

I had a '97 Bayliner with epoxy painted seat wood. It would hold water under the seats and rotted out the seat wood in 2 years. Replaced it using the urethane spar varnish on the new plywood, and it still looked like new 7 years later when I sold the boat.
