Innovation in Propeller Design

Yes, as in propellers for outboard motors. . .

By Gary S. Vasilash

When someone refers to the “Motor City,” it is typically thought of in terms of cars.

But Detroit is (1) on the Detroit River and (2) located in the “Great Lakes State.”

Which brings us to Sharrow Engineering, a Detroit-based advanced engineering and design firm.

And within Sharrow Engineering there’s Sharrow Marine, which produces propellers for outboard motors.

The company has just launched the Sharrow X10 for Mercury V10, 350- and 400-hp engines.

The propeller, which is CNC machined from a stainless-steel alloy, “offers superior performance, greater fuel efficiency, and a significantly quieter ride,” according to Greg Sharrow, the founder and CEO of the company.

Here’s an interesting thing: Greg Sharrow invented the propeller design not while pursuing advances for outboard motors. Rather, he was working in video production and worked to develop a quieter drone.

It was determined that by reducing or eliminating tip vortices there is significant noise-reduction—as well as the other benefits that are achieved for the propellers used in water.
