Navy Series Outboard Motors

The Navy Series is our range of more powerful electric outboard motors and provide efficient and clean power for small vessels. Thanks to the direct-drive technology, the Navy electric outboard boat motor series is quiet, maintenance-free and reliable.

3kW (~6HP)
NAVY 3.0 Evo Electric Outboard Motor
Powerful 3kW electric outboard provides efficient and clean power for small vessels.
6KW (~10HP)
NAVY 6.0 Evo Electric Outboard Motor
Powerful 6kW electric outboard provides efficient and clean power for small vessels.
Power with Range

Our Navy 3.0 kW (~6HP) electric outboard motor is designed for power with long range. Enjoy the quiet and exhaust-free electric boating experience with our direct-drive design (no gearbox required) which essentially eliminates the requirement for ongoing maintenance.

High Performance

Leading the way in innovation of electric outboard motors, we're dedicated to sustainable boating. Our Navy 6.0 kW (~10HP) outboard motor strikes the right balance between power output and cruising range.

We recommend the E80 battery for Navy 3.0 Evo, and E175 battery for Navy 6.0 Evo. Other configurations can be created, but parallel connection is required.

To power a Navy 3.0 Evo with E40, you need two E40 batteries in parallel. To power a Navy 6.0 Evo with E80, you need two E80 batteries in parallel.

Our original E-Series battery has the best unit price on the market, as low as $0.46 per WattHour.

The E-Series battery weighs 70% less than the lead-acid battery with equivalent usable capacity, and costs 50% in five-year use.

Due to incompatible communication protocol, when powered by third-party batteries, the ePropulsion motor cannot access real-time battery status and apply the best operation strategy.

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.

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.

How to find the right shaft length?

Yes, it is designed for extensive use in the saltwater. We choose high-quality aluminum alloy as the base material, and apply anodizing coating and powder coating on top of it. For more info, please check ePropulsion Blog: How do we make an outboard corrosion-resistant?

See below for transom height and most suitable shaft length:

30cm - 40cm: Extra Short Shaft*
40cm - 50cm: Short Shaft
50cm+: Long Shaft

* Extra short shaft is available for Spirit 1.0 series only.
