Introducing Navy

Navy Series is the backbone of ePropulsion electric outboard motors. It provides efficient and clean power for aluminum fishing boats, dinghies, daysailers and cruising sailboats, suitable for saltwater and freshwater. Thanks to the direct-drive technology, the Navy electric outboard boat motor is quiet, maintenance-free, and reliable.

*The performance data is based on a 12-foot aluminum boat with one person, powered by one Navy 3.0 Evo with one E80 battery and one Navy 6.0 Evo with one E175 battery, in calm lake water.

With one charge, you can go 40 miles with Navy 6.0 Evo, or go fishing all day long at trolling speed.

Can I use E40 to power Navy 3.0 Evo or E80 to power Navy 6.0 Evo?

  • Yes, but parallel connection is required. To power one Navy 3.0 Evo with E40, you need two E40 batteries in parallel. To power one Navy 6.0 Evo with E80, you need two E80 batteries in parallel.

Can I use third-party batteries to power Navy 3.0 / 6.0 Evo?

  • First, our original E-Series battery has the best unit price on the market, as low as $0.46 per WattHour.
  • Second, the E-Series battery weighs 70% less than the lead-acid battery with equivalent usable capacity, and costs 50% in five-year use.
  • Third, because of incompatible communication protocol, when powered by third-party batteries, the ePropulsion motor cannot access real-time battery status and apply the best operation strategy.
  • Despite all these, if you still prefer third party lithium or lead-acid batteries. The nominal battery voltage should be 48V. The continuous discharge current should be over 62.5A for Navy 3.0 Evo and 125A for Navy 6.0 Evo.

Do I need to charge the Evo top mount control?

The Evo top mount control has a built-in battery and it can be self-powered by its solar panel. When you use it with wireless connection and the control is at low battery level, you could charge the Evo top mount control with a communication cable.
