Product of the Week- The Ecowind varying pitch propeller
by Kevin Woody on 12 Oct 2010

Max-prop Ecowind propeller SW
A propeller that will adapt to changing situations by automatically varying its pitch under differing load conditions. It sounds like a good deal, particularly for long range cruising sailors, and that's just what the manufacturer claims.
The result is claimed to be higher top speeds in both calm and rough conditions, significantly lower fuel consumption, extended range under power, better acceleration and much less engine noise at cruising speed due to the lower RPMs.
If PYI's latest addition to their Max-Prop automatic feathering propeller line, the Ecowind, is anything like promised, it will be a real game-changer.
How does it work?
The Max-Prop ECOWIND propeller by PYI features a cutting-edge patented spring-based technology that adjusts propeller pitch automatically to its optimum position based on load. When the boat accelerates, the pitch flattens to allow the engine RPMs and boat speed to increase rapidly.
As a vessel’s speed progresses, the load on the propeller decreases and the pitch increases. Compared to fixed pitch propellers, the ECOWIND offers greater speed with the same RPMs as well as the same boat speed at a lower RPM.
'The Max-Prop ECOWIND represents a huge leap forward in propeller design and technology,' said Fred Hutchison, PYI Inc. 'Delivering enhanced performance with improved speed under power as well as significant fuel savings, the ECOWIND propeller demonstrates PYI’s continued commitment to providing innovative technology solutions to boating enthusiasts.'
The ECOWIND propeller features Max-Prop’s renowned automatic feathering design. While underway, each individual propeller blade slices through the water allowing it to feather past, rather than being dragged.
Also known for its reverse efficiency, going from forward to reverse, the propeller rotates the shaft of the blade to provide the same productivity in either direction.
Max-Prop ECOWIND propellers range in size from 14- to 22-inches, are purpose built for the harsh sea environment and protected by a 3-year warranty.
Pricing and Availability:
Max-Prop ECOWIND propellers are available for purchase from authorized PYI dealers and distributors worldwide and have a suggested retail price range of US $4,800 to $5,600.
