ePropulsion Spirit 2 Outboard, Seabob Electric Jet Scooter, Battery Backed DC Charging

🏄🏾‍♂️ SEABOB Electrifies the Water: Germany’s High-Performance Electric Jet Scooter

A German-built electric watercraft that blends exhilarating performance with clean, quiet operation on and under the surface.

Electric propulsion in the marine world tends to focus on outboards, charging infrastructure, and commercial transitions—but SEABOB adds another dimension: pure electric recreation that gets riders moving across and beneath the water with precision and power. Developed by German manufacturer CAYAGO AG, the SEABOB is a handheld, self-propelled electric water scooter favored by yacht owners, charter fleets, and watersports enthusiasts worldwide. Unlike traditional personal watercraft, SEABOB combines advanced electric drive technology, robust battery systems, and streamlined hydrodynamic design to deliver a smooth, responsive ride with zero emissions at the point of use.

Unlike electric outboards designed to push a hull, the SEABOB is itself the vessel. A sealed lithium-ion battery pack powers the patented E-Jet Power System, which draws water through a high-efficiency pump and expels it as thrust. Riders hold two ergonomic grip handles, control speed with intuitive thumb levers, and lean to direct motion—whether skimming the surface or diving below. The effect is more like piloting a water-borne electric sports car than riding a traditional jetski: quiet, torque-rich, and remarkably agile.

Technical performance is a key part of SEABOB’s appeal. Entry models like the F5 series offer continuous power outputs in the neighborhood of 5 kW, while higher tiers such as the F5 S push peak outputs above 10 kW. The flagship F9 model ramps that up further with peak power exceeding 12 kW, allowing surface speeds up to approximately 20 km/h and underwater maneuvering at similarly brisk paces. Battery capacities range from roughly 1.7 kWh to 2.5 kWh depending on model and configuration, with runtime varying by speed and depth but typically supporting sessions of 30–60 minutes of active use. Charging is handled through an onboard port with a dedicated charger, bringing the onboard battery back to full in a few hours from standard shore power.

Build quality and materials reflect SEABOB’s premium positioning. The outer hull and structural components use high-strength alloys and corrosion-resistant composites to withstand saltwater environments, while internal thermal management sustains performance even under heavy loads. Trim options and accessories—from tow rings to special deck mounts—add versatility for boat integration or solo use. Some editions are co-branded with luxury automotive marques, underscoring SEABOB’s lifestyle appeal and the crossover between performance engineering and marine leisure.

While SEABOB doesn’t replace propulsion systems on larger e-boats, it complements the wider electrification trend by showcasing what electric marine power can feel like: immediate, silent, and engaging. For yacht owners, it enhances guest experiences; for charter operators, it’s a standout amenity; and for electric boat advocates, it demonstrates that zero-emission technology can thrive in high-performance, recreational contexts as well as utility applications.

🌊 Battery-backed DC arrives at Fowey—Aqua superPower scales up

A battery-buffered DC charger at Fowey Harbour shows how marine fast charging can work where grids are constrained.

Marine fast charging is moving beyond straightforward marinas and into tougher locations. A new installation at Fowey Harbour in Cornwall demonstrates a practical path forward: a battery-backed DC pedestal that delivers high-power charging even when the local grid can’t supply peak loads. Developed by Aqua superPower, the site is part of the Electric Seaway project along England’s southwest coast and is described as the world’s first battery-buffered DC charger deployed in a marine environment.

Why the buffer matters is simple. Marinas often reach grid limits long before boater demand tapers off. By charging a stationary battery at a manageable rate and discharging at higher power when vessels plug in, the system avoids multi-year utility upgrades. That approach improves user experience and opens the door to electrification at heritage harbours and constrained ports where trenching, transformers, or new feeders face physical or regulatory barriers.

The Fowey installation also signals how networks can scale. Aqua superPower expanded its footprint through 2025 with new sites across the UK and Italy; pushing into constrained locations tests a model that can be replicated for regional corridors. For operators, battery-backed nodes shorten permitting timelines and reduce demand risk as electric fleets grow and charging profiles diversify.

This architecture aligns with near-term vessel roadmaps. Today’s portable outboards and small cruisers are well served by AC or low-power DC, while performance craft and commercial boats increasingly ask for 50–150 kW DC. Buffered pedestals can meet those peaks, capture lower-carbon off-peak energy, and share data upstream for smarter scheduling—driving higher utilization and better economics for marina owners.

⚙️ ePropulsion Debuts Spirit 2 to Widen Low-Power Choices

ePropulsion has introduced the Spirit 2 electric outboard, expanding its low-power lineup with a more capable, flexible option for anglers, sailors, and small-boat owners who want quiet, zero-emission propulsion without the weight and complexity of larger systems. The new model builds on the original Spirit platform with a meaningful jump in output, a larger integrated battery, and a feature set aimed at real-world usability on dinghies, tenders, and lightweight skiffs.

At the core of Spirit 2 is a 2 kW electric motor, delivering nearly double the continuous power of the original Spirit while remaining firmly in the compact outboard class. For short bursts, a Boost mode increases output to 3 kW, providing extra thrust for maneuvering in current, pushing into wind, or accelerating a loaded boat. Operating speeds fall in the roughly 1,700 to 2,100 rpm range, and while top speed ultimately depends on hull and load, ePropulsion indicates performance approaching 9.5 knots at full power on suitable boats.

Energy storage is handled by an integrated 1,539 Wh lithium battery, one of the larger capacities available in a self-contained outboard of this size. This allows Spirit 2 to balance portability with practical endurance. At wide-open throttle, typical runtime is just under an hour, extending to roughly one hour and forty-five minutes at half power and up to around three hours at quarter power. Standard charging takes about eight hours, while an optional fast charger can reduce that to roughly two hours. The battery is rated for approximately 1,000 charge cycles to 80 percent state of health, aligning with expectations for recreational electric marine use.

A notable feature carried over and refined from earlier Spirit models is hydrogeneration. When the propeller is driven by water flow—such as while sailing or being towed at speeds between about 3 and 16 knots—the motor can generate electricity and feed it back into the battery. Under favorable conditions, output can reach roughly 300 to 380 watts, helping offset onboard power use and modestly extend range during longer passages. Spirit 2 also adds practical energy utility, including a USB-C port capable of delivering up to 45 watts for charging electronics, and compatibility with inverter accessories that allow the battery to serve as a small portable power source ashore.

Despite the increased capability, Spirit 2 remains focused on ease of handling. The motor unit weighs just over 10 kilograms, with the battery adding roughly another 10 kilograms, keeping the total system weight in the 20 to 21 kilogram range depending on shaft length. A foldable tiller with adjustable angles, a color display, integrated kill switch with safety lanyard, and steering range of approximately 180 degrees all contribute to a user-friendly experience. Trim angles can be set at multiple positions up to 21 degrees, while tilt positions include shallow-water operation and near-vertical lift for beaching or trailering.

Taken together, Spirit 2 fills an important gap in ePropulsion’s portfolio. It offers more authority and versatility than entry-level electric outboards, while remaining far lighter and simpler than higher-power systems designed for larger boats. For sailors looking for an efficient auxiliary, tender owners who value portability, and anglers seeking clean, quiet propulsion, Spirit 2 widens the set of realistic electric options in the 1–3 kW class and underscores how quickly this segment of the marine market continues to mature.
