I am not sure without seeing the pictures, but I believe those "weights" where put in from the factory. Mine had them too, ugly, and poorly put in. Mine broke lose, and knocked around some plumbing. I was lucky it didn't knock out one of the seacocks and sink the boat.

I am in the process of closing/bracketing my transom. I am putting a livewell in the back, and converting my in floor live well to a fish box. I am hoping this will help balance the boat. I have a large top (see my avatar), and it is a little nose heavy.
