Flux Marine

Market position

Flux Marine positions itself as a developer of purpose-built high-performance, zero-emission electric outboards, claiming its 100 HP outboard on a 22-foot dual console reaches top speeds near 35 knots with more than 75 nautical miles of range on a charge. It publicly debuted its outboard line at the 2021 Newport International Boat Show, where it received two best new product awards. Coverage identifies Torqeedo's scale among competing suppliers in the electric outboard segment.

The company emphasizes a ground-up electric propulsion design rather than a retrofit of EV components into a conventional outboard housing, continuous horsepower ratings measured at the propeller, standard mounting and modular batteries for integration across hulls, elimination of combustion maintenance items such as impellers, spark plugs, filters and winterization, IP67 waterproofing with fault-triggered de-energization, and IoT connectivity with over-the-air updates and fleet telematics.

Technology

Flux Marine's system comprises an all-electric outboard with continuous power ratings at the propeller, modular lithium-ion battery packs with thermal management, solid-state power electronics, and standardized mounting for integration across hull types. All electronics, including the outboard and battery pack, are waterproofed to IP67; an array of sensors monitors operation and de-energizes the system on a detected fault. A low-power mode engages below 10% state of charge to extend range via software limits. Units are IoT-connected for over-the-air updates, and a fleet telematics platform is used for monitoring and predictive maintenance. The company describes its designs as patent-pending.

Go-to-market

The company markets directly to boaters via on-water demonstrations and sea trial bookings, online configuration and an inventory listing that includes units held at its own Bristol, Rhode Island location and at third-party dealers such as EMO Electric in Brookhaven, New York and Jersey Jet Boats in Brick, New Jersey. In parallel, it runs a hull manufacturer partnership program covering engineering review, CAD and electrical integration planning, pilot builds and on-water validation, then production launch with technician training and documentation. Earlier go-to-market steps included preorders for standalone outboards and in-person demonstration centers on Greenwich Bay, Rhode Island and Steelpointe Harbor, Connecticut.

Recreational boaters buying dual console, center console, aluminum sport and pontoon packages; hull manufacturers and boat builders seeking to electrify product lines; and commercial watercraft operators, including fleets that use telematics-based monitoring.

Geography

R&D, corporate and manufacturing operations in Rhode Island, with headquarters reported in Bristol, RI; demonstration locations on Greenwich Bay, RI and Steelpointe Harbor, CT; and dealer inventory in Brookhaven, New York and Brick, New Jersey. The company describes delivering outboards to companies and customers around the United States.

History

Following its origins in Princeton-funded research from 2015 and roughly a decade of development, Flux Marine debuted its all-electric outboard line at the 2021 Newport International Boat Show. In March 2022 it announced a $15.5 million oversubscribed Series A led by Ocean Zero LLC, established R&D, corporate and manufacturing headquarters in Bristol, Rhode Island, secured tax incentives from the State of Rhode Island, worked with Connecticut's AdvanceCT on manufacturing, and partnered with the RCI Group on a destination center at Steelpointe Harbor. A 2025 report describes a further $15 million equity funding round led by Collide Capital to scale production.

Risks & controversies

Reported adoption barriers include limited marina charging infrastructure and higher upfront costs for electric packages relative to gasoline equivalents, along with competition from established electric outboard suppliers. Funding figures for the 2025 raise come from secondary coverage that itself notes undisclosed terms and cites differing cumulative totals across data providers, and no revenue figures are public.
