Features
Thrust and efficiency across a wide speed range
According to the manufacturer, the Omega 33 delivers good thrust and efficiency across a wide speed range, and the company calls it the most advanced waterjet in its class.
Stainless steel pump unit
The pump unit is made of stainless steel; according to the manufacturer, this extends service intervals and product life.
Patented Dual Angle Shaft (DAS)
Rotating the shaft support structure 180° switches between 0° and 4° shaft angles (drive shaft inclination) while the waterjet's own angle stays the same and no extra parts are needed.
Modular Intake Geometry (MIG)
Intake inserts come in high-, medium- and low-speed versions and can be changed to suit vessel speed and bollard pull requirements without modifying the external structure.
Applications: Demanding commercial and military vessels
