I had already commented that the Nicro 4" stainless Day/Night 1000 I bought from West Marine for use in my foredeck hatch last spring is removable. There is a collar attached to the boat with 4 screws, and the vent itself pushes into the collar. I'm pretty sure that the deck plate you use to seal up a Nicro cowl vent would also work to seal up the collar.
I had to go to West Marine this afternoon to pick up some parts for my Zodiac inflatable, so I decided to look at the Nicro vents in stock to see if the design had changed to one that was not removable. The inventory of Day/Night Plus Solar Vents (the name has apparently changed) that they had is the same as mine. There is a collar with seal that attaches to the deck, a fan blade that can be flipped over to give either intake or exhaust, and a removable fan. The 3" moves 600 cu.ft/hour and the 4" moves 1000. See page 536 of the 2013 WM catalog, or search their website for part number 10447084. There are, indeed, two styles of Nicro vents. The other one is called a Mini Vent 1000, moves 700 cu.ft/hour when the sun is shining and gives passive ventilation if you have a breeze at night, and it is attached directly to the deck without the need for a "Nicro Vent Deck Plate". It IS cheaper than the Day/Night vent. Also see page 536 or search for part number 183733. Perhaps this is the one that Dennis was thinking about in his earlier response. BTW, there is also a Nicro Air Vent 500, which is passive only (moves 600-1000 CU.Ft/hr is a 15 knot breeze) and attaches directly to the deck. FWIW, it is only $49.

It can be pulled it out of its sleeve and be replaced with a cap. I'm on my second battery. They don't last long but keep in mind they can go through 365 deep cycles each year. Also more realistically I think winter kills them because I forget to take it out each time. It works well in my forward hatch but keep in mind to also install a passive vent at the opposite end so you actually create air movement. I cut a vent into my companionway and installed a louvred oak floor diffuser which vents the boat well and looks really sharp. No mild, must or mildew. Brent 27-5 Lake Winnipeg.
