Following professional installs on large cruisers on our lake I used an Omnimount
to hang a 32" flat screen on the salon/head bulkhead. It's thru bolted in 1" plywood, solid & will allow more tilt & rotation than you stated. Their customer service was helpful chosing which model # for my screen & situation. When I had that I google it & Vann's, an online discount electronic store in MT or WY had the lowest price. A week later I had it in hand. The mount is well built & stylish.
