Sharrow Marine has developed a new type of propeller that the company calls the "future of propulsion". The technology initially seemed too expensive but Sharrow has now introduced the affordable variant MX-A after all. It is particularly designed for smaller outboard engines.
Sharrow has redesigned the common marine propeller by replacing the usual blades with twisted 'loops'. These reduce or prevent vortices and cavitation. As a result, less energy is wasted, leading to an efficiency increase of up to 30%. This is combined with a very smooth and quiet drive.
These remarkably shaped propellers with twisted loop are revolutionary for the marine sector. They are much quieter than traditional propellers and show huge efficiency gains. Propellers are designed to take in a liquid and use a rotary motion to propel that liquid through. In a way, it is a logical extension of Archimedes' screw, which was probably used in ancient Egypt for thousands of years before it was described by Archimedes in 234 BC. Over time, there have been few revolutionary changes in design. Many ships are fitted with propellers that still bear many similarities to 1700s propellers.
Sharrow's 150-patent design has now won numerous awards from the shipping and technology industries. The design has been tested on numerous ships with some remarkable results. The brand new MX-A now brings Sharrow's innovative propeller technology within reach of a wider market. According to Sharrow's statement, the new propeller works with 2-stroke, 4-stroke, in-line 4-cylinder and power thrust outboard engines from major brands such as Mercury, Yamaha, Honda, Suzuki, Tohatsu, Johnson and Evinrude.
Unlike the larger stainless steel variant, the MX-A series is CNC-machined from aluminium. The striking red colour is an interesting addition that brings just that little bit more to the boater.
