Q:Excuse me, why do some of the engines behind the speedboat spray a small column of water into the air?

The propulsion of the speedboat is accomplished by the rotation of the propeller of the engine behind the boat. When the propeller rotates in the water, the thrust of the water supply and the reaction force of the water push the boat forward. The propeller speed is fast, the thrust force of the water supply is large, and the speed of the speedboat runs quickly. Because the propeller does not rotate deep in the water, and the thrust is reversed horizontally, some of the water that is thrust by the propeller will break away from the surface of the water and is sprayed far into the water column.

Q:150 horsepower speedboat, 100 kilometers fuel consumption?

Boats equipped with weapons, some boats are also equipped with 20 to 76 mm caliber naval gun, the larger tonnage of the speedboat may also include mines, deep water bombs and so on. The matching sensing systems include search, detection, weapon control, communications, navigation, electronic warfare, and so on.

Q:Do I need a driver's license to drive a speedboat?
