What is it?

I bought some items for my boat online and this was in the package also. I did not order or pay for it, but have no idea what it is.
Anyone know?
It is made of what appears to be Corian and is 5.5 inches long by 3.5 inches wide with a pocket routed out in one side of one of them and the other is just flat. I think they mount together.

I have something like those on my bay boat...they cover up the water intakes to my front and rear livewell aerators.....

looks like it goes up on the front deck of your boat and your trolling motor sits over it..... just what it looks like to me

Looks like a big iPhone case.

My browser would not let me view the images but it sounds like a transducer plate. I think this is what it is called anyway. I have seen them in Cabelas and you are supposed to mount this to your transom and then mount your transducers to this plate.

Wow, 8 screw holes to mount one rod holder?
