Mark II Plugs?

Ok, so my Mark II has two plugs on the back. I don't understand what these do, when I want them open, and when I want them closed. Seems to me I would always want them open...no? Thanks for any help on this seemingly stupid question

The little flappy valve in there will plug up with junk and then water will flood back into your boat at rest. If you want have dry feet leave the plugs in. If are going to take water over the bow or bring it aboard via scuba gear then pull the plugs before getting underway.

I replaced the flapper valves on mine, and even then at rest the boat filled with water to where it was above the rear deck. Now I just leave the one remaining stopper in place all the time. I would only remove them just BEFORE you start the motor to take off, and only if there is a lot of water in the hull.

OK, I think I get it, basically those just let water out from inside. So, unless I have water inside probably should keep them closed. Thank you for the help.
