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

Digital Operation

Tailored Control and Display Solutions to Suit Every Boater

  • Digital Display

    Provides real-time monitoring of key information including power output, remaining runtime, battery level, voltage, and more.

  • Electric Start

    Start instantly at the push of a button, eliminating the effort of pull starts.

  • Magnetic Kill Switch

    Enhances safety by instantly shutting down the motor in case of emergency.

  • Smooth Throttle Changing

    Delivers precise throttle response with a clear, comfortable feel in both forward and reverse.

  • Adjustable Max Power Output

    Allows you to set a maximum throttle limit, making the motor suitable for children or rental applications.

  • Ambidextrous Operation

    Throttle can be operated comfortably from either the left or right hand for flexible control.

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.
