Yamaha’s HARMO® Electric Outboard System Makes U.S. Debut at IBEX

Posted 9/28/2021

KENNESAW, Ga., Sep. 28, 2021 –  Yamaha Marine introduced its HARMO electric outboard system to the U.S. market today during the 2021 International Boatbuilders Exhibition and Conference (IBEX®) in Tampa, Florida.
Coupling a 48-volt power supply with a high-yield, low-drag 3.7-kilowatt motor, HARMO’s rim-drive electric motor and specially encased impeller provide an incredible 225 pounds of static thrust - the equivalent of a conventional 9.9-horsepower gas-powered motor. Run times depend on battery type, size, configuration and operational parameters.  
While rim drive motors have been deployed for thrusters and other marine applications, this is the first application in an outboard motor.
“HARMO is the perfect system for horsepower or internal-combustion restricted waterways. Ultimately, it is up to our boat builder customers to decide how to integrate it into their boats, and we are eager to see the result,” said Ben Speciale, President, Yamaha Marine U.S. Business Unit.
The system includes Helm Master® EX system controls (including the joystick) for simple, intuitive operation in a clean, quiet system. HARMO also features integrated Digital Electric Steering (DES), and a 140-degree total steering angle, combining strong, smooth acceleration with incredibly sharp handling and control. The control system can rotate a single-engine boat within its length and allows for true lateral operation in twin configuration. Additionally, its extreme 74-degree tilt angle helps keeps the impeller clear of the water when not in use.
The motor offers virtually silent operation, quick response, crisp and dramatic maneuvering, and easy-to-understand and operate controls. Available in single or twin configurations, the HARMO motor unit weighs 121 pounds and the system can effectively maneuver boats up to 32-feet in most conditions.
The latest product to emerge from Yamaha’s CommandBlue™ engineering and design philosophy, HARMO combines advanced propulsion technology, environmental awareness, future vision and proven joystick control to provide high thrust and maneuverability
Yamaha’s CommandBlue philosophy drives the design and development of new, connected technologies and technology-based products from the consumer’s perspective, specifically to simplify boating and instill deep feelings of confidence, satisfaction, and excitement while on the water.
Deriving its name from the harmony that exists between a vessel, its propulsion system, its passengers and the environment, HARMO is available through boat builders only and in European markets now. U.S. availability is expected within 18 months.
For boat builders, marine industry dealers, aftermarket suppliers and buyers, designers, repairers, surveyors, and boatyard/marine operators, IBEX® is the single source for the latest boatbuilding technologies, tools, and materials.
