Features
Features
Long-term validation on the factory test boat
According to the manufacturer, the Omega 42 has run for thousands of hours on the company's own test boat in coastal and offshore conditions, covering continuous operation, harsh environments and high-load duty.
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, making it easier to suit engine room constraints such as engine oil sump depth.
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: Professional vessels; patrol boats and fast workboats
