Understanding Water Jet Propulsion - Marine Insight
2021年7月27日 · Water jet propulsion has several advantages that make it an attractive choice when choosing propulsion systems. Speed of vessel is very important when it comes to small crafts, and water jet-powered boats are able to reach 40 knots (75 kmph) even in poor conditions.
Pump-jet - Wikipedia
A pump-jet, hydrojet, or water jet is a marine system that produces a jet of water for propulsion. The mechanical arrangement may be a ducted propeller (axial-flow pump), a centrifugal pump, or a mixed flow pump which is a combination of both centrifugal and axial designs.
Water-jet drive - All boating and marine industry manufacturers
A water-jet drive is a propulsion system capable of generating great speed by shooting a stream of water astern. These systems are used in high-speed boats. Such drives pump water at great velocity through a nozzle pointing astern, propelling the boat forward.

Waterjets: When to Use, Pros and Cons - DMS Marine Consultant
Waterjets work by pumping a LOT of water through a closed duct. The acceleration of this water creates a forward thrust for propulsion. Figure 2‑1 shows a typical arrangement for a waterjet. Suck the water in at the bottom, the impeller adds power, and …
What Is Waterjet Propulsion On Small Vessels? - Maritime Page
2024年10月25日 · Most high-speed vessels worldwide employ waterjet propulsion, which is an effective form of propulsion. You can assess whether your boat needs water jet propulsion by looking at two key parameters: the operational parameters and the performance output.
Marine waterjet Drive, Pump-Jet, marine waterjet propulsion system
The propelling force is generated by adding momentum to the water through accelerating a specific flow of water sternward. Water flow from under the vessel is fed through an inlet duct mounted at the transom, flush to the hull bottom, into an …
