Water in TI hull. Am I missing drain plug?

Just bought a Tandem Island. I put it on the trailer after a shakedown cruise and there was a lot of water in the hull. It was draining out a hole in the stern. I looked there and the hole is threaded, making me believe there should be a plug inserted in that hull. Without a plug, that's probably where the water is coming in. See picture.

I looked in the manual and I don't see anything about a plug. Should one be there? Can anyone share a picture of theirs or a part number so I can talk to my dealer?

Thanks,

Evan
