Product Overview
The propulsion equipment from Marine Jet Power (MJP), specifically the DRB Double Reversing Bucket Waterjet, is engineered for high-efficiency, high-maneuverability marine propulsion across a wide range of vessels from commercial crafts to performance yachts. Its mixed-flow pump design and inboard hydraulics deliver superior acceleration, exceptional thrust, and superior reversing control for demanding operational profiles. The DRB series is built with durable duplex stainless steel construction for longevity in even harsh marine environments.
Key Features
- Double Reversing Bucket: Split duct reversing bucket gives enhanced maneuverability and versatile thrust control superior to conventional waterjets.
- Mixed-Flow High-Efficiency Pump: Optimized thrust and fuel efficiency across a broad speed range.
- Inboard Hydraulics: Integrated hydraulics for steering and reversing provide precise control and save installation space.
- Duplex Stainless Steel Construction: Pump body and steering units made for outstanding corrosion resistance and long service life.
- Multiple Intake Options: Available with steel, metal, or composite intake for tailored installations.
- Reliable in Harsh Conditions: Designed to handle debris, sand, and rough water without performance loss.
