PRODUCT DATA SHEET The MJP Ultrajet range excels where high bollard pull and exceptional acceleration is a specified craft requirement and boat speed must not be sacrificed to achieve this. Features & Benefits • Excellent resistance to cavitation in displacement craft - high thrust at low speed • Light weight and compact design with a variety of on jet mounted control systems • Superior manoeuvrability. Ability to accelerate quickly, reverse, stop, rotate, hold station and move sideways for ease of docking. • Higher mid-range thrust for improved cruising speed and economy Description MJP Ultrajet 251 with a 250mm (9.84”) diameter impeller provides higher thrust per horsepower and can be used with engines up to 261 kW. The MJP Ultrajet 251 incorporates an efficient and robust axial flow pump unit utilising four or five bladed impellers to match the specific engine power at a range of input speeds. MJP Ultrajet drives have been developed for commercial, pleasure and military craft. The MJP Ultrajet 251 can be supplied with a full range of both hydro-mechanical and electro-hydraulic steering and reverse control systems. • Lower vibration and noise levels than other propulsion methods • Wide range of MJP-developed mechanical and electrical reversing controls • Standard rubber impeller shaft bearing or optional composite bearing if dry running is required Planing Craft Maximum input power 261 kW (350 bhp) Single jet up to 4 tonnes (8,816 lb.) Twin jets up to 9 tonnes (19,836 lb.) Triple jets up to 15 tonnes (33,060 lb.) Displacement Craft Maximum input power 112 kW (150 bhp) Single jet up to 8 tonnes (17,632 lb.) Twin jets up to 18 tonnes (39,672 lb.) Triple jets up to 28 tonnes (61,712 lb.) Note: The displacement figures can often be exceeded on good hull shapes.
