When deciding on the right waterjet solution there are many variables to consider – from size, weight and power to efficiency, reliability, support and ease of integration. All of this can make it a complicate process, but it doesn’t have to be. At Wärtsilä we have been delivering waterjet solutions that meet customer needs and all these variables for over 40 years.
At the heart of this is our Smart Marine Vision, where collaboration and the most advanced digital technology come together to deliver solutions with greater efficiency, safety, security and reduced environmental impact throughout the life of the asset.

▬ Modular Waterjets Propulsion System by Wärtsilä ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
The Wärtsilä WXJ modular waterjets represent the state-of-the-art, delivering outstanding benefits and performance and offering a high-level of customisation with a wide variety of options available depending on the vessel type.
The Wärtsilä WXJ series features an improved axial pump design, which boosts performance with an increased thrust of as much as 3%, while the improved cavitation margins help reduce the environmental impact by lowering noise levels. This axial pump design comes with a 25% reduction in mounting flange diameter, 10% overall weight reduction and a 35% increase in cavitation margin compared to its predecessor, the “LJ type” with a mixed flow pump design, while the small transom interface dimensions, and best in class weight are unchanged.
▬ Applications of Modular Waterjets ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
The characteristics of a waterjet make it a good propulsor for numerous applications:
- High speed vessels; waterjets have better propulsion efficiency at ship speeds over 25-30 knots.
- Shallow draft vessels; the integrated steering function provides benefits for rescue vessels, inshore passenger ferries, landing crafts & special work boats.
- High power density; the pressure built-up in the waterjet inlet allows small dimensions.
- Maneuverability; waterjets have integrated steering and reversing with quick response times.
Examples of such applications include:
- Fast ferries
- Littoral combat ships
- Fast patrol boats
- Rescue vessels
- Fast yachts
- Fast supply vessels and workboats
- Landing craft
▬ Key Benefits of Modular Waterjets ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
Wärtsilä axial waterjets are single stage, compact, high performance systems that combine mixed flow properties with an axial construction. The results, less space needed and increased waterjet cavitation margins for optimum vessel operational flexibility. For naval architects, the axial jet technology allows to apply a larger power density onto narrower hulls to achieve top vessel performance:
- Lowest size to weight ratio in the market
- Axial pump design means less space on the transom
- Worldwide availability, including China, Japan, Korea, etc.
- Inboard mounted thrust bearing block, for increased life and easy maintenance
- Optional inboard hydraulics
- High-performance components in Duplex stainless steel to prevent wear and corrosion
-Impeller tip clearance guaranteed due to axial shape and no risk of impeller housing collisions.
- Customisable to meet your needs
- Fully integrated solutions available
