Flux Marine has closed a $15 million funding round to expand production of its electric outboard motors and powertrain technology. The Bristol, Rhode Island-based company reports leading North American deliveries of high-voltage electric outboards in 2024 and 2025, bringing total capital raised to over $30 million since 2020.
Highlights
- Funding from existing investors, customers, and new backer Collide Capital supports transition from fleet validation to scaled production
- Company has delivered more high-voltage electric outboards than any North American competitor over the past 18 months
- Modular powertrain architecture integrates with multiple boat builders including Scout Boats, Highfield, Flagship Pontoons, Hyfoil, and Zodiac
- In-house technology development spans power electronics, cooling systems, battery management, and fleet telematics platform
Production Scale Following Validation Program
The capital infusion supports Flux Marine’s shift from customer-driven fleet testing to volume manufacturing. CEO Ben Sorkin stated the company invested significant time and resources in real-world validation before scaling production. The testing program placed systems with early adopters in demanding ocean environments to verify performance and incorporate customer feedback.
Flux Marine has fully commercialized its 115HP electric outboard and modular battery pack, marketed as the only high-voltage electric outboard designed from clean-sheet principles currently in North American production.
Boat Builder Partnership Strategy
The company’s business model centers on supplying propulsion technology to established boat manufacturers rather than producing complete vessels. The modular electric powertrain and battery architecture is designed for integration across multiple hull types, enabling boat builders to add electric options to their product lines.
Current manufacturing partners include:
- Scout Boats
- Highfield
- Flagship Pontoons
- Hyfoil
- Zodiac
Christophe Lavigne, President of Highfield Boats, noted the company tested multiple electric marine products before selecting Flux Marine’s system, citing the maintenance-free closed-loop cooling system, belt drive, and lower unit design.
Fleet Telematics and Remote Management
Flux Marine developed a proprietary Fleet Telematics Platform providing cellular connectivity to all deployed systems. The platform enables real-time system health monitoring, remote diagnostics, over-the-air software updates, and trip data analysis. The company states AI-powered predictive maintenance and route optimization features are in development.
Applications for Flux-powered vessels span aquaculture workboats in Maine, lake rental fleets, and twin-outboard superyacht tenders in the British Virgin Islands.
Technology Development and Dual-Use Applications
The company maintains in-house development of its complete electric propulsion stack, including power electronics, cooling systems, battery packs, battery management systems, software, and telematics. Sorkin stated this vertical integration approach provides control over performance, quality, supply chain management, and cost reduction trajectory.
Flux Marine reports receiving requests for its powertrain technology from industries beyond marine applications. The company has begun delivering solutions to uncrewed platform manufacturers, leveraging demand for domestically produced, rapid-turnaround powertrain and energy products.
The 40,000-square-foot Rhode Island facility houses both development and manufacturing operations, supporting customers in undersea and aerospace sectors.
Market Position and Outlook
Stephen Petranek, Operating Partner of Ocean Zero and investor in Flux Marine, stated the marine electrification market requires empowering existing boat builders rather than replacing them. He noted established manufacturers like Highfield, Scout, and Zodiac possess decades of expertise in boat design and manufacturing economics.
Flux Marine positions its approach as enabling these partners to innovate in their established market segments while the company focuses on propulsion system development.
