Battery Recharged While Sailing: The Electric Outboard That Makes Fuel Runs History
The Electric Evolution: Power Meets Portability
Electric propulsion is no longer a niche market; it is the definitive future for clean, quiet boating. ePropulsion, celebrating ten years of electric propulsion excellence, solidified its leadership at METSTRADE 2025 with the introduction of the new Spirit 2. This updated model significantly expands the Spirit range to 2 kW, delivering enhanced power while maintaining a lightweight, compact size. The Spirit 2 is designed to revolutionize the experience for dinghies and day cruisers, proving that silent, eco-friendly power can meet demand for strong performance.
The Game Changer: Hydrogeneration Technology
The key technical feature that sets the Spirit 2 apart is its Hydrogeneration function. This technology allows the battery to recharge while the vessel is under sail, actively recouping energy. Operating effectively between 3 and 16 knots, the system can generate up to 1.5kW of power. This capability extends range sustainably, maximizing the battery’s value and optimizing space for effortless adventures. For sailing applications, the integrated steering lock secures the motor for reliable control when using the yacht’s rudder.
Performance and Precision: The 3 kW Boost
The Spirit 2 is engineered to deliver immediate performance when needed. The 2 kW battery-integrated electric outboard includes a 3 kW sport mode for enhanced performance, ideal for upstream use or against strong currents. Performance is optimized through an updated hydrodynamic design that minimizes propeller vibration and features a streamlined propeller rotating at 2000 RPM. This focus on precision ensures a smoother, more powerful ride than traditional gas alternatives.
Beyond Propulsion: A Portable Power Station
The Spirit 2’s utility extends far beyond propulsion. Equipped with an expanded 1539Wh battery capacity, the unit includes a Type-C port that transforms the outboard into a portable power station. This feature allows users to charge mobile devices up to 100 times without a wall plug, making it perfect for extended adventures, fishing trips, or picnic outings on day boats. The quick-connect battery is cable-free and floatable, enhancing portability and ease of use.
The Verdict: The Final Word on Portability
ePropulsion’s Spirit 2, which will be available in Spring/Summer 2026, is a confident leap forward in marine electric technology. By mastering core technologies, including direct-drive motors and advanced cooling systems, ePropulsion ensures durability and dependability. The Spirit 2’s combination of enhanced power, extreme portability (motor and battery weigh just 20.6 kg), and the sustainable innovation of hydrogeneration sets a new, higher standard for the industry.
