Sharrow. reaches out to a larger market with the aluminum MX-A propellerSharrow Marine View 2 Images

Sharrow Marine has quietly been working to disrupt the marine industry with a reimagined propeller it calls the "future of propulsion." The tech originally looked like it might be too expensive and make/model-specific to see that future to fruition in a substantial way, but Sharrow has now introduced the more affordable, consumer-friendly MX-A. Less than half the price of previous models, the latest Sharrow propeller works with smaller outboards of just 40 hp and up, and it's compatible with motors from a who's who of the largest, most popular brands in the industry.

Sharrow has redesigned the common marine propeller by replacing the usual blades with gently twisted loops that promise to eliminate efficiency-sapping tip vortices and cavitation. Put simply, less energy is wasted, leading to claimed efficiency boosts of up to 30%, not to mention smoother, quieter overall performance.

Not only has Sharrow's 150-patent-deep design won a host of major awards from the marine and tech industries, it's been put to the test on numerous vessels, both internally and by third-party reviewers, with some intriguing results.

The first time we took a look at Sharrow's unique propeller design, we noted that the one big drawback seemed to be price. At about US$5,000 a pop to start, they were an estimated 10 times more than a typical propeller, a steep upfront investment that might be difficult to recoup even with a 30% efficiency boost.

These appear to work for boat propellers as well as smaller plastic ones being able to make drones fly quieter and more efficiently.

Why are they machining this out of a solid block of aluminum, instead of investing in foundary tooling so they can cast these ?

What aluminum alloy are they using? It doesn’t say, and matters a lot for marine durability.

They wouldn’t work in the weed moss infested marsh and bayous of Louisiana. They’d clog up.
