The ePropulsion Navy 3.0 Evo is a 3 kW electric outboard motor featuring direct-drive propulsion, hydrogeneration, and remote control. The motor is intended for use on vessels including sloops, tenders, RIBs, and sailboats, and is supplied without a drive battery.
Selecting the model
- Short shaft: typically for a transom height of 40–50 cm.
- Long shaft: typically for a transom height above 50 cm.
- Control: the model offered includes remote control. Other Evo controls, such as side mount, dual remote, or tiller, are available separately.
- Battery: not included. A suitable 48 V battery and charging solution are required for a complete installation.
Measure the transom height before ordering. For more power, the ePropulsion Navy 6.0 Evo is also available.
Power and application
The Navy 3.0 Evo delivers 3 kW. As a practical comparison, this corresponds to approximately 5 hp of propulsion power up to 8 hp of thrust. ePropulsion also mentions a theoretical comparison of approximately 6 hp. Electric power, thrust, and the motor power of a combustion engine are not directly interchangeable.
As a practical Marinaut guideline, the motor can bring boats of approximately 900 to 2,700 kg to cruising speed and lighter boats of approximately 300 to 950 kg towards hull speed. Actual performance depends on hull, load, battery, propeller, wind, and current.

| 1,000 W | 8.6 km/h | 4 hours | 34.1 km |
| 1,500 W | 9.7 km/h | 2 hours 40 min. | 25.7 km |
| 2,000 W | 10.2 km/h | 2 hours | 20.4 km |
| 2,500 W | 12.8 km/h | 1 hour 35 min. | 20.5 km |
| 3,000 W | 16.4 km/h | 1 hour 20 min. | 21.9 km |
Factory test with a 12-foot aluminum boat, one person, a Navy 3.0 Evo, and an E80 battery on calm inland water. Actual values will vary per boat and conditions.
Hydrogeneration
While sailing, the Navy 3.0 Evo can charge a suitable ePropulsion battery via the rotating propeller, provided the required sailing conditions are met. Yield varies with speed, installation, and conditions. Consult the manual for the conditions.
Propulsion and control
- Brushless 48 V DC motor with direct-drive transmission.
- Stepless forward and reverse.
- Digital display showing power, battery status, voltage, and remaining runtime.
- Adjustable maximum power, e.g., for rentals or quiet use.
- Magnetic kill switch.
- Support for top-mount, side-mount, dual-remote, and tiller control.
- Wireless or wired communication, depending on the chosen control and installation.
- Closed liquid cooling without the use of external water.
Battery and installation
The motor is supplied without a battery. ePropulsion recommends a 48 V E-Series LiFePO4 battery. The E80 4.1 kWh model is a suitable combination and was also used for the official performance table.
- A suitable battery, battery charger, wiring, main switch, and fuse are required for operation.
- For an installation with steering, a suitable steering cable and steering wheel are also required.
- Other suitable 48 V batteries can be used provided that voltage, current capacity, protection, and communication are correctly configured.

- Steering link bar for two motors: available in different lengths. A dual installation requires sufficient transom width and distance between the motors.
- Wireless ePropulsion emergency stop wristband is available as an option.
Practical experience
Jan Romeijn, console boat of approx. 750 kg: reported a quiet sailing experience and a speed of up to approx. 10 km/h after a trip of approximately 6.5 hours. The test was performed with one person. This is personal practical experience and not a guaranteed performance.
Sea trials with different boats

Speeds and range vary per boat, battery, load, and conditions. In tests with a smaller battery, a previously mentioned range may have been converted; therefore, only directly stated speeds and test conditions are shown here.
Comparison with Haswing Ventura F.50
- Choose the Haswing Ventura F.50 when a more compact 2.5 kW motor and a lower purchase price are important.
- Choose the Navy 3.0 Evo when 3 kW power, hydrogeneration, and the extensive Evo control options are important.
