What is this for?

[widespreadpanic]

Sport 200V purchased recently. Found this under the passenger seat. What goes here? What's it for?
Looks like something should screw in there. Thanks for any input

The lock mechanism for the center observer seat. I believe it’s an option. My boat can with it.

That is mostly correct. It's the mounting point for the jump seat. You get a pair of locking "clips" for lack of a better term that bolt into those nut certs. There a pair of long threaded pins that mount to the jump seat that go through the side of the passenger base and are locked into those mounting points. I had Nautique Parts make me a jump seat over the winter and installed it in the spring. It hasn't been out of the boat since. Great option to have.

We also had them make the center cushion for the sundeck which we like as well.
