MJP Ultrajet marine jet 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 1342 kW (134 to 2172 bhp) per jet with the appropriate direct drive or reduction gear ratio. MJP Ultrajet propulsion systems are rated for the real-world operating conditions encountered by commercial and military boats.
