Catalogue excerpts

Features & Benefits • New low profile for lower decks • New hydrodynamic intake housing • Higher inspection cover to prevent • Improved reversing with new reverse deflector • New inboard hydraulic cylinder for reverse deflector operation • New sealed drive bearings for reduced maintenance • Less static hull immersion required for initial priming • Wide range of Ultra-developed reversing controls • Standard rubber impeller shaft bearing or optional composite bearing if dry running is required • Light weight and compact design with a variety of on jet and remote mounted hydraulic control systems • High propulsive efficiency • Superior manoeuvrability. Ability to accelerate quickly, reverse, stop, rotate, hold station and move sideways craft - high thrust at low speed. • Lower vibration and noise levels than other propulsion methods. (305mm) diameter impeller provides higher thrust per horsepower when matched to modern engines in the of a range of high performance 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 UltraJet 305 is derived from the Ultra and Dowty jet drive range used in military and commercial applications for almost forty years. The UJ305 incorporates an efficient and robust axial flow pump, reverse and steering controls, and has many of the same design features as used in the current "UltraJet designs". Planing Craft (above 25 knots) Maximum input power 336 kW (450 HP) Higher input powers may be approved upon review of application details. Suitable for craft displacements as follows:- Displacement Craft (below 15 knots) Maximum input power 224 kW (300 HP) Suitable for craft displacements as follows:- Note: The displacement figures below can often be exceeded on good hull shapes.
