How to choose this product
propeller-nozzle

A propeller nozzle is a cylinder surrounding the propeller. It accelerates water flow, increasing propeller efficiency.

Applications

Such devices increase propeller output by providing additional thrust.

Technologies

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.

Advantages

- Increased output

Disadvantages

- Creates drag at higher speeds
