Boat water-jet drive: max. 5000 hp
max. 1200 hp | ULTRAJET 452 ULTRA Dynamics

The UltraJet 452 is derived from the Ultra (formerly Dowty) jet drive range, which has
been used extensively in military and commercial applications for over 40 years.
The UltraJet 452 is a single stage axial ﬂow design incorporating an impeller with a
diameter of 450mm (17.7 inches), which develops higher thrust per horsepower at
boat speeds between 0 - 20 knots than any equivalent sized waterjet on the market.
The hydraulic reverse control system has been totally integrated onto the waterjet,
simplifying the installation for the boat builder and allowing the complete reverse
control system to be factory tested before despatch.
