Electric outboards for larger boats

Powered by a choice of separate rechargeable batteries, you’ll have clean, quiet, and environmentally friendly propulsion.

Designed for convenience, the lightweight and compact motors are effortless to lift, transport, and stow, whether ashore or onboard.

These waterproof batteries are not only far lighter and more compact than traditional fuel tanks, but they also eliminate the need for engine noise, oily bilges, and unpleasant fumes onboard.

Thanks to the efficient direct-drive system, the motors have fewer moving parts, eliminating the need for ongoing maintenance or servicing.

Highly versatile, these long-range electric outboards are interchangeable between various types of 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
River boats
Sailing Yachts

Made for ePropulsion Motors

The batteries share data with our motors, optimising performance and efficiency.

Hydrogeneration Empowers Sailors

The Navy 3.0 / 6.0 Evo models come equipped with a hydrogeneration function, enabling you to harness electricity directly from both wind and water. As a leader in the field, ePropulsion continues to pioneer groundbreaking innovations in electric outboard motor technology.
  • The Navy 3.0 and 6.0 Evo outboard motors have the capability to charge ePropulsion batteries by utilising water flow to drive the propeller, provided certain conditions are met.
  • The hydrogeneration statistics are derived from actual tests conducted with the anti-ventilation plate installed.
  • The Navy 6.0 Evo has been rigorously tested using a 12.6" x 8.7" three-blade aluminium propeller, which is available for separate purchase.

Shaft Length Recommendation

The NAVY Series motors come in two shaft lengths, Short and Long.

Transom HeightShaft Length
40-50cm / 15.7-19.7 inchesShort
Higher than 50 cm / 19.7 inchesLong
