A propeller nozzle is a cylinder surrounding the propeller. It accelerates water flow, increasing propeller efficiency.
Such devices increase propeller output by providing additional thrust.
These nozzles increase the velocity of the water flowing over the propeller and reduce disturbance at the tips of the blades. The higher water speed creates a pressure difference, increasing thrust.
How to choose
Nozzle and propeller should be chosen together. Criteria include engine power, propeller diameter and related factors.
- Optional custom size can be manufactured.
- Increased output The nozzle increases the thrust at low speeds.
- High efficiency nozzle increases bollard thrust up to 30% at low
