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 • ow profile for lower decks and hydrodynamic L intake housing • Higher inspection cover to prevent overflow • mproved reversing with new reverse deflector I • Inboard hydraulic cylinder for reverse deflector operation • Sealed drive bearings for reduced maintenance • ess static hull immersion required for initial priming L • ide range of MJP-developed mechanical and electrical W reversing controls • tandard rubber impeller shaft bearing or optional S composite bearing if dry running is required Description The MJP Ultrajet 340 with a 340mm (13.4”) diameter impeller provides higher thrust per horsepower when matched to modern engines in the 242-448 kW range. The MJP Ultrajet 340 is one of a range of high performance MJP Ultrajet drives developed for commercial, pleasure and military craft. Single stage design utilising four or five bladed impellers to match the specified engine power at a range of input speeds. The MJP Ultrajet 340 is derived from the Ultra and Dowty jet drive range used in military and commercial applications for almost forty years. The MJP Ultrajet 340 incorporates an efficient and robust axial flow pump, reverse and steering controls, and has many of the same design features used in the current MJP Ultrajet range. • ight weight and compact design with a variety of on jet L and remote mounted hydraulic control systems • High propulsive efficiency • uperior manoeuvrability. Ability to accelerate quickly, S reverse, stop, rotate, hold station and move sideways for ease of docking • Excellent resistance to cavitation in displacement craft - high thrust at low speed • ower vibration and noise levels than other propulsion L methods Planing Craft Maximum input power 448 kW (600 bhp) Single jet up to 9 tonnes (19,836 lb.) Twin jets up to 20 tonnes (44,080 lb.) Triple jets up to 32 tonnes (70,528 Ib.) Displacement Craft Maximum input power 242 kW (325 bhp) Single jet up to 15 tonnes (33,060 lb.) Twin jets up to 33 tonnes (72,732 lb.) Triple jets up to 55 tonnes (121,220 lb.) N ote: The displacement figures can often be exceeded on good hull shapes.
