I intend to thru-hull mount a high-speed bait well pick-up and transducer. I have made reinforcment plates from 3/4" plywood and 3 layers of epoxy. Should I glass them down and if so using what layup?? or should I just "glue" them with 4200?? The bait well pick-up will have a true sea-cock above. Here's a pic of the blocks....the small holes were from nails so I could epoxy both sides and will be covered by the fittings.
