I have made comments about the curvilinear shape of the screw before. It has to do with controlling cavitation formation. A screw on a boat is not like a screw in a chunk of wood. Nor is it like a wing, it can not 'stall'. There are many many reasons it is shaped like it is. What you see there is the rough shape. There are many things about the surface of the screw and exact shapes that are the real secrets.

The smaller propeller in the back spins ar the same speed and direction as the main propeller.
