Flux Marine has raised $15 million to scale production of its electric outboard motors and powertrain systems, according to Bloomberg. The Rhode Island-based company says it has delivered more high-voltage electric outboards than any other North American manufacturer over the past 18 months, bringing its total funding to more than $30 million since 2020.
The latest funding round—supported by existing investors, customers and new investor Collide Capital—will support Flux Marine’s shift from customer validation programs to larger-scale manufacturing. The company has commercialized a 115-horsepower electric outboard and a modular high-voltage battery pack, both developed in-house. Flux Marine’s 40,000-square-foot facility in Bristol, Rhode Island, houses development and production operations, including power electronics, cooling systems, battery management and software.
Flux Marine focuses on supplying propulsion technology to established boat builders through its modular powertrain architecture rather than producing complete vessels. Current partners include Scout Boats, Highfield, Flagship Pontoons, Hyfoil and Zodiac. The company reports that its systems are being deployed in a range of applications such as aquaculture workboats, rental fleets on inland lakes and twin-outboard tenders for larger vessels.
The company has also developed a telematics platform that provides remote diagnostics, real-time system monitoring, software updates and fleet management tools. Flux Marine says artificial intelligence–based predictive maintenance and routing functions are in development. Beyond recreational and commercial marine markets, the company is supplying powertrain solutions to customers in the uncrewed systems sector and has begun delivering components to undersea and aerospace applications.
Flux Marine expects demand for high-voltage electric propulsion to increase as boat manufacturers introduce more electric variants and as customers seek lower operating costs and reduced maintenance requirements. The company positions its approach as enabling boat builders to expand electric offerings while it focuses on propulsion system development and vertical integration.
