Uses of outboard engines

Outboard engines, also known as outboard motors or outboard motors, are propulsion systems installed outside the hull of a ship, mainly used to drive the ship forward. It integrates multiple key components such as the engine, transmission and propeller, and is usually placed at the stern or side of the ship. When working, its lower half will naturally immerse in the water, and when the boat is docked, it can be easily tilted to emerge from the water. 

Specific uses
‌Water entertainment‌: Outboard engines are widely used in personal leisure and entertainment boats to provide power support, suitable for use in inland rivers, lakes and offshore environments. 
‌Coastal fishing‌: In the field of fisheries, outboard engines help fishing boats to carry out fishing operations and provide efficient power support. 1.
‌Commercial operations‌: In the fields of commercial operations, government law enforcement, etc., outboard engines are used for various vessels that require efficient power and flexible operation. 
‌Military applications‌: In the military, outboard engines are used for boats and bridges that perform reconnaissance, landing and other tasks to provide necessary power support.

Structural composition and working principle
Outboard engines are mainly composed of the following parts:

‌Engine‌: Usually a gasoline engine or a diesel engine is selected, which is arranged on the top of the outboard motor to convert fuel into power‌
‌Transmission‌: It smoothly transmits the original power to the propeller and has the function of speed conversion, including the drive shaft and the transmission gear set‌
‌Propeller‌: Usually a propeller or other equivalent device, located at the bottom of the outboard motor, converts the torque provided by the engine into thrust to propel the boat forward‌

The working principle of the outboard engine mainly depends on the backward thrust generated by the propeller. By flexibly adjusting the thrust size and direction of the propeller, the boat can achieve a variety of actions such as forward, turning and backward‌
