Marine Jet Power (MJP) has announced three new sizes in the X-Series range of waterjets. Expanding upon the proven 280, 310 and 350 X sizes, the new 400, 450 and 500 X feature MJP’s duplex stainless-steel, mixed-flow pump design and welded aluminum intake.

The new additions to the range will service vessels ranging in size from 26m – 40m/85'–131' and up to 2070 kW/2,775 hp. The X-Series is built for fast patrol craft, military applications as well a commercial workboats and search and rescue vessels.

“The new X-Series sizes demonstrate MJP’s commitment to engineering high-performing waterjets that are not only easy for shipyards to install but also easy to maintain for end users and operators,” MJP CEO, Jonas Tegström, said in a statement announcing the new waterjets.

The 400, 450 and 500 X-Series models have been designed in compliance with full class approval with dual feedback sensors and a stainless-steel hydraulic tank. The jet models will be configured with MJP's JetMaster3 electronic control system, which under class rules come with a dual power supply, redundancy, and back-up system. ​​The fabricated intake has been developed for larger vessels, optimized through Computational Fluid Dynamics (CFD) to offer both high-top speed and high thrust.

Other key X-Series features include a responsive nozzle with central fin, optimized reverse bucket, and a fully integrated hydraulic pump, resulting in a highly efficient waterjet that’s easy to install, operate and maintain. 

“The new 400, 450 and 500X waterjets are a new era for MJP,” said Adam Mills, X-Series product manager. “We can now offer X-Series on larger vessels up to 40m, helping shipyards to streamline the installation process saving them time and money, while reaping the benefits of a high performing, mixed-flow, duplex stainless-steel waterjet at a lower price point.”

The new X-Series sizes are available now and the first 400X unit will be delivered to an undisclosed customer in Asia next quarter.
