Boat propellers, or props for short, are rotating fan-like devices used on boats or other marine vessels to generate thrust and propel the boat forward or backwards. Depending on the vessel's design and purpose, they come in various shapes, sizes, and materials, operating underwater while attached to the boat's shaft.

2. How Do Propellers Work?

The work of a propeller can be best understood by the principle of Newton's third law of motion, stating that for every action, there is an equal and opposite reaction. By spinning rapidly, boat propellers create pressure differences on their blades, effectively pushing water in one direction, which propels the boat in the opposite direction. This concept, "thrust," is the key to understanding how propellers can move boats through the water.

3. Types of Boat Propellers:

a. Fixed Propellers: As the most common type, fixed propellers are permanently attached to the boat's shaft and maintain a constant pitch and angle. They are reliable and usually the most affordable but lack the adjustability of other propeller types.
