Notoriously Expensive Loopy Outboard Propeller Drops 50% in Price
4th October 2025
Nautical disruptor Sharrow Marine has been hard at work fast-expanding its lineup of innovative twisted-loop propellers, releasing tweaked models for new applications while also ramping up overall production. A year ago, that work saw it launch the MX-A propeller for smaller outboards, effectively cutting pricing by more than half compared to previous launches. Now it’s doing it again with the AX, smashing downward through the four-figure floor for the first time with a propeller designed for even smaller outboards and kicker motors. Buyers seeking to put the company’s striking, efficiency-boosting loop-blades to work can now do so for well under $1K.
Officially introduced on Tuesday, the all-new Sharrow AX propeller follows the MX-A in using a lightweight aluminum construction that delivers corrosion-resistant performance without the expense of stainless steel. Unlike with the MX-A. The AX slides below the targeted 40-hp+ market of the MX-A and is designed specifically for small outboards ranging between 6 and 30 hp.
“With the launch of the Sharrow AX, we’re proud to introduce our technology to the small-engine market,” said founder and CEO Greg Sharrow. “Whether used as a primary prop on a small outboard or as an auxiliary kicker for trolling, the AX offers smoother handling, quieter operation and unmatched fuel efficiency.”
Toroidal propellers represent the first significant advance in propeller design since the discovery of the cavitation problem in 1885. Go to YouTube and search for ‘toroidal propeller’ and be prepared to be amazed.
