A Sustainable Future for Boating

ePropulsion electric outboards and electric motors for boats represent a huge step ahead in creating a sustainable future for boating for sailboats, fishing boats, work boats, day boats, dinghies and tenders.

Electric outboard motors are proving to be the reliable and efficient alternative to traditional outboard engines.

Powered by lithium batteries, with more power and range than you would achieve with an equivalent tank of fuel, electric outboards are quiet, clean and kinder to wildlife and the environment.

Rechargeable from solar panels, 12 volt and now hydro-generation too, ePropulsion’s innovative electric outboard motors are versatile across a wide range of powerboats and sail boats.

Spirit 1 Plus/Evo – Portable Electric Outboard Motor for tenders and dinghies

The Spirit 1.0 Plus is a versatile 1kW electric outboard engineered for a wide range of vessels, from dinghies and tenders to fishing boats and small sailboats. Compact yet powerful, it is equipped with a high-capacity 1.2kWh integrated lithium battery, delivering extended range and reliable performance on the water. Combining lightweight construction, responsive handling, and clean energy, the Spirit 1.0 Plus sets a benchmark in portable electric propulsion.

The EVO model enhances this capability with a hydrogeneration function, allowing the battery to recharge while under sail.

Navy Evo 3.0 or 6.0 – Remote control with Hydrogeneration charging

for river cruisers, sail boats and work boats

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.
The ePropulsion Navy Evo 3.0 and 6.0 are long range electric outboards, capable of powering larger displacement boats at faster speeds over greater distances.

The robust Navy Evo 3.0 will comfortably power a 2.5 ton boat using one battery. Equivalent to 6hp petrol outboard.

The Navy Evo 6.0 is ideal for a displacement boat up to 5 tonnes with two batteries. Equivalent to 9.9hp petrol outboard.

Powered by a choice of three different sizes of separate 48v rechargeable batteries, you’ll have clean, quiet, and environmentally friendly propulsion.

Far smaller and lighter than their equivalent in fuel tanks, these waterproof, rechargeable batteries mean no engine noise, no oily bilges and no grease or fuel fumes on board either.

Lightweight and compact, the motors are easy to lift, transport and store ashore or onboard.

The efficient direct drive propulsion means few moving parts, and no maintenance or servicing either.
