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.

E-Series Lithium Battery

Unlock the full potential of your Navy electric outboard with ePropulsion’s 48V E-Series lithium iron phosphate battery, the perfect match for clean and powerful performance.

Competitive pricing

Unit price is as low as £0.46 per watt-hour.

High energy density

70% less weight and space than standard lead-acid batteries.

Longer life cycles

Boasting an impressive 3,000 cycles at 80% State of Health (SoH).

Made for ePropulsion Motors

With an integrated BMS, the batteries optimise motor performance, efficiency, and safety.

Shaft Length Recommendation

The Navy Series motors are available in two shaft lengths: short and long.

Transom Height	Shaft Length
40-50cm / 15.7-19.7 inches	Short
Higher than 50 cm / 19.7 inches	Long
