Flux Marine is a Bristol, Rhode Island–based marine propulsion company focused on advancing electric outboard motors and integrated battery systems. Its product portfolio features a fully commercialized 115-horsepower electric outboard paired with a modular battery pack. The company’s modular powertrain architecture fits a broad range of hulls, enabling partners such as Scout Boats, Highfield, Flagship Pontoons, Hyfoil, and Zodiac to introduce electric boat packages quickly. Aimed at both recreational and commercial markets, Flux Marine’s technology offers a cleaner, quieter alternative to traditional gasoline engines. Since 2020, the company has raised more than $30 million in total funding. The latest capital will be applied to scaling outboard production and expanding sales of its core technology.
