marine propulsion

Marine propulsion refers to the methods and technologies used to move boats and ships through water. The main types include engines powered by fuel, such as diesel or gasoline, which drive propellers, and alternative systems like electric motors or sails. The choice of propulsion affects speed, efficiency, and environmental impact. In recent years, innovations like hybrid systems and eco-friendly fuels have emerged, aiming to reduce pollution and improve energy use. Overall, marine propulsion is crucial for shipping, fishing, and recreational boating, facilitating global trade and transportation.
