The piece of solid mahogany wood you seek is called the rear post. There are two, one on each side of the top console, rear facia. I think they are identical cuts. If I needed a piece like the rear post, I would call Bob Latourelle, Haverhill, MA. He can cut a piece for you and ship it to you. Bob always has an ad on Craigslist Boston, entitled: "Boston Whaler Mahogany wood consoles and seats (Haverhill). You can reach him via 978-837-8808.
