The Ultra-Efficient Toroidal Propeller


 Sharrow stacks propellers into a contra-rotating design for outboards and sterndrives that require them



The Ultra-Efficient Toroidal Propeller has taken a significant leap forward with the introduction of the Sharrow CX, a contra-rotating propeller system1. This new design integrates the company’s signature looped propellers into a contra-rotating setup, promising enhanced energy efficiency and reduced noise levels1.

The Sharrow CX features two propellers rotating in opposite directions around a single shaft1. This configuration, already known for its efficiency in marine propulsion, is further enhanced by Sharrow’s twisted looped blades1. The company anticipates notable improvements in efficiency, agility, and maneuverability1.

Previous testing of Sharrow’s single propellers has demonstrated significant enhancements in range, reverse thrust, and noise reduction1. The Sharrow CX, despite its premium pricing, underscores Sharrow’s commitment to quality and innovation, solidifying its position as a leader in the field of marine propulsion.

In conclusion, the Sharrow CX represents a significant advancement in marine propulsion technology, combining the efficiency of contra-rotating propellers with the performance benefits of Sharrow’s toroidal blade design1. It’s a promising development for the future of efficient and sustainable marine transportation1
