Navy Series
Navy Evo 3-6kW 6-9.9HP**
Electric Outboards
HydrogenerationLow Maintenance Direct-Drive
The Navy Series delivers powerful, efficient, and reliable electric propulsion with outputs from 3 to 6 kW (equivalent to 6–9.9 HP). Its direct-drive system ensures quiet operation and minimal maintenance, while integrated hydrogeneration technology allows the battery to recharge under sail. Combining performance with sustainability, the Navy Series is the ideal choice for boaters who demand both power and eco-friendly innovation.


Electric outboards for larger boats
Powered by a choice of separate rechargeable batteries, these electric outboards deliver clean, quiet, and environmentally friendly propulsion.
Designed for convenience, the lightweight and compact motors are easy to lift, transport, and stow whether on board or ashore. The external waterproof batteries are far lighter and more compact than traditional fuel tanks, while eliminating engine noise, oily bilges, and unpleasant fumes.
Thanks to an efficient direct-drive system, the motors contain fewer moving parts, reducing wear and removing the need for regular servicing or maintenance.
Highly versatile and offering impressive range, these electric outboards can be paired with different vessels, including:
- Yacht tenders and dinghies
- Aluminium fishing boats
- SIBs (small inflatable boats)
- RIBs (rigid inflatable boats)
- Motor boats
- Day sailers
- Yachts up to 5 tons

Hydrogeneration Empowers Sailors
The Navy 3.0 / 6.0 Evo models are equipped with hydrogeneration technology, enabling the battery to recharge from water flow while sailing. This system enhances energy efficiency, extends range, and reduces reliance on shore power, marking a significant advancement in electric propulsion engineering.
- The Navy 3.0 and 6.0 Evo outboards are equipped with hydrogeneration, enabling ePropulsion batteries to recharge by harnessing water flow to drive the propeller, provided specific operating conditions are met.
- Hydrogeneration data is based on real-world testing with the anti-ventilation plate installed.
- The Navy 6.0 Evo has been tested extensively with a 12.6" × 8.7" three-blade aluminium propeller, available as an optional accessory.
