I have the same, plus 2 more on the forward side of each bench seat. I'm pretty sure they're just for draining out any water that might collect in those air spaces (not the transom one). I think the transom one needs to be in, at least on mine. I'm pretty sure it's below the water line, however I haven't had mine in the water to verify.
