Marine Jet Power drives (waterjet propulsion) feature high efficiency single-stage axial-flow pump elements with a variety of intake housings and control options. A wide range of impellers match most marine diesel engines from 100 to 1620 kW (134 to 2172 bhp) per jet with the appropriate direct drive or reduction gear ratio. Marine Jet Power propulsion systems are rated for the real-world operating conditions encountered by commercial and military boats.

Marine Jet Power drives excel when thrust is required to quickly accelerate the boat, to permit getting on plane with a full fuel and passenger load, to maintain attitude at cruise throttle settings, even in turns, and to maintain control in following or quartering seas yet still providing the best top speed possible with the available power.

Marine Jet Power Waterjet Propulsion & Control Systems

Marine Jet Power waterjet propulsion and control systems are used by many organizations for various applications, including Navy, Coast Guard, police, government departments, pilot boats, offshore oil & gas service vessels, offshore windfarm service vessels, port & harbor security, passenger, workboat, fishing, and recreation craft. 

The Marine Jet Power range of waterjet propulsion and control systems are designed, manufactured, and supported by Marine Jet Power (formerly Ultra Dynamics). Their propulsion units are well suited to the performance and durability requirements of military, paramilitary, commercial, and passenger craft in real-world conditions for more than 50 years.
