ePropulsion Navy 6.0 Evo: Best-Value Electric Outboard for Tenders and Day Boats
The Navy 6.0 Evo delivers 6 kW peak on a 48 V lithium pack, offers 4–6 hours at cruising throttle, and undercuts comparable ICE outboards on total five-year cost of ownership.
ePropulsion's Navy 6.0 Evo has become the most widely specified electric outboard for sailboat tenders and small day boats in the 3–6 m range. The motor produces 6 kW peak and 3 kW continuous at 48 V, drawing from ePropulsion's 2.9 kWh or 5.8 kWh clip-on lithium pack. At a 2.5 kW cruise setting, the 5.8 kWh pack gives approximately 4.5 hours of runtime, which covers most tender use cases comfortably.
The system integrates a tiller-mounted LED display showing pack voltage, estimated remaining range, and motor temperature. A Bluetooth interface connects to the ePropulsion app for trip logging, power-use history, and firmware updates over the air. The app also provides a discharge curve so operators can plan range accurately under different load profiles.
One significant advantage over competitors is the modular battery design. The 48 V packs are hot-swappable; a spare fully charged unit clips on in seconds, doubling range without any wiring work. For charter operations running multiple daily trips, this makes the Navy 6.0 Evo genuinely practical in a way that permanently wired batteries are not.
On five-year total cost of ownership, the Navy 6.0 Evo compares favourably with a 6 hp petrol outboard when fuel, impeller replacements, winterisation, and carburetor servicing are included. The electric unit has no cooling-system service interval, no spark plugs, and no fuel system — maintenance is limited to an annual inspection of the propeller and electrical connections. European retail pricing is approximately €3,200 for the motor with the 5.8 kWh battery.
