Water jet propulsion, also known as jet propulsion or hydro jet propulsion, is a method of propelling a watercraft by expelling a high-velocity jet of water backward. This technology is commonly used in various types of boats, ships, and personal watercraft. Unlike traditional propellers that rely on rotating blades to generate thrust, water jet propulsion systems use the principle of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
