Sharrow Props Tested a Sportsman Masters 267
Sportsman Masters 267: 9.2 MPH FASTER at 3000 RPM
12% Better Fuel Efficiency at 24 MPH with Sharrow Propeller
Sharrow propellers have proven remarkably consistent in outperforming conventional 3- 4- and 5-bladed propellers on a wide variety of boat and motor combinations. Most recently, Sharrow tested a Sportsman Masters 267 center console bay boat powered by a 300-hp Yamaha outboard, and again the innovative propeller proved superior to a standard 3-blade stainless steel propeller by multiple standards.
Sharrow propellers can be custom engineered and manufactured for each boat and motor combination, and the company works with boat owners to assure a perfect match for any given package. The propellers include a lifetime guarantee in workmanship and a 30-day swap policy.
This speed chart shows that Sharrow TrueAdvance propeller gained a speed advantage over the traditional stainless steel 15.25” x 18” 3-blade propeller at about 2000 rpm and 9 mph and continues to outperform up to 5000 rpm on the Sportsman. The maximum 61% advantage is evident at 3000 rpm, where the Sharrow has already brought the hull to a full plane while the conventional prop is still struggling to get it over the hump.
The Sharrow propeller not only shows better fuel efficiency when the Sportsman is on plane, maxing out at 12% better at 25 mph, but also does 25% better at around 7 mph. This can be a big advantage for anglers who troll for extended periods offshore. Better fuel efficiency saves money at the pump, and also extends the range on a given fuel capacity.
Sharrow TrueAdvance propellers effectively get a better grip on the water, and advance at more nearly their design pitch with each revolution as seen in this chart. The Sharrow propeller shows the greatest advantage at 3000 rpm, where it already had the boat on plane and moved the boat forward 14.91” per turn compared to only 9.21” per revolution for the conventional prop, which was still struggling to bring the boat to full plane. The Sharrow was a remarkable 62% better. It maintained an advantage all the way to wide-open throttle, with the prop actually exceeding its design pitch between 3500 and 5000 rpm.
Invented by Greg Sharrow, the Sharrow Propeller is recognized as the first major advancement in propeller technology since the 1830s. Its design has solved the most basic problem of rotary propulsion. Specifically, tip cavitation and vortices have been eliminated or significantly reduced, offering incredible performance gains over traditional propellers.
Users also report less noise and vibration and more positive low-speed steering control in both forward and reverse.
