Can a ship's propeller having four controllable pitch propellers be replaced with two blade propellers?
It is possible to replace one kind of propeller (sometimes called a screw) with another kind. When moving to the "less complex" two blade propeller, the mechanisms that control the pitch of the blades of the propeller with pitch control will be abandoned or removed. There may be a lot more to this, but the basic answer is that you can replace one kind of propeller with another kind, as long as the "handedness" of the screw is the same as the one coming off. Or you'll go backwards in "Ahead" and ahead in "Back" on the direction selector.

Did the hovercraft replace anything?
Hovercraft replaced many things, here is a list: Hovercraft replaced problems rescuing people from floods, mud, sand and ice. (Wake up Pakistan) Hovercraft replaced problems with submerged obstacles that can damage propellers. Hovercraft replaced having to commute long distances, just cross the river, lake, lagoon etc. Hovercraft replaced having to wait until high tide to have fun on the water. Hovercraft replaced problems reaching your waterside home. Hovercraft replaced falling through the ice when the ice thins in springtime. Sell the snowmobile, buy a Hov Pod.
Article regarding U.S. Navy Submarine propellers?
All official information on U.S. Navy Submarine screws (the proper term for a ship's propeller) is classified Secret/NoForn. However, you can find some information in Jane's Fighting Ships, though it of course isn't verifiable. However, having kept all of Jane's books on my own boat, I will say it's not inaccurate in certain areas.
