The ePropulsion Spirit 1.0 Plus is a portable electric outboard motor with tiller steering and a power output of 1 kW. The motor is available in extra short shaft, short shaft, and long shaft versions. Depending on the chosen model, the motor is supplied with or without the removable 1,276 Wh Spirit Battery Plus.
Choose the right model
The choice of model determines the shaft length, condition, price, and whether the battery is included. Both new and pre-owned models are available. For the previously offered pre-owned long shaft with battery, a three-month warranty is stated; the battery has been tested and has at least 90% capacity. Always check the selected variant when ordering.
- Extra short shaft: for a transom height of approximately 30 to 40 cm
- Short shaft: for a transom height of approximately 40 to 50 cm
- Long shaft: for a transom height of more than 50 cm
Measure the transom height from the motor mounting point to the bottom of the boat. The required shaft length may differ from that of a fuel-powered motor.
Power and application
The Spirit 1.0 Plus delivers 1,000 watts, which ePropulsion compares to approximately 3 HP. This is a theoretical comparison based on thrust and performance; kW and HP are not directly equivalent.
As a practical guideline, Marinaut suggests that the motor is suitable for bringing boats up to approximately 900 kg to cruising speed and lighter boats up to approximately 300 kg toward hull speed. The actual result depends on hull shape, waterline, load, wind, and waterway conditions. The motor is widely used on dinghies, RIBs, sloops, fishing boats, and smaller sailboats.
For larger or heavier boats, the ePropulsion Navy 3.0 Evo and ePropulsion Navy 6.0 Evo are possible alternatives.
Performance with Spirit Battery Plus
| Power | Speed | Run time | Range |
|---|---|---|---|
| 35 W | approx. 3.5 km/h | 36 hours and 25 minutes | approx. 129 km |
| 65 W | approx. 4.3 km/h | 19 hours and 35 minutes | approx. 85.3 km |
| 125 W | approx. 5.6 km/h | approx. 10 hours | approx. 56 km |
| 250 W | approx. 7.1 km/h | approx. 5 hours | approx. 35.5 km |
| 500 W | approx. 8.5 km/h | approx. 2 hours and 30 minutes | approx. 21.3 km |
| 750 W | approx. 9.2 km/h | approx. 1 hour and 40 minutes | approx. 15.3 km |
| 1,000 W | approx. 10 km/h | approx. 1 hour and 15 minutes | approx. 12.5 km |
These factory values were measured with one person in a 12-foot aluminum boat, with one Spirit Battery Plus and in calm water. The actual speed, run time, and range will vary depending on the boat, load, weather, and operating conditions.

- Weight: approx. 8.7 kg
- Dimensions: 416 × 275 × 202 mm
- Protection: IP67
- Charging temperature: 0 to 45 °C
- Operating temperature: -20 to 60 °C
- Lifespan: at least 500 cycles at specified operating conditions
- Standard charging time: approx. 8.5 hours
- Fast charging: approx. 3.5 hours with the optional fast charger
The battery can be charged via mains power and, with optional accessories, via 12 V or solar panels. To connect an ePropulsion E-series battery, the appropriate external battery cable is required.

Real-world experiences
- On a Gentle 430 with six people, the motor was experienced as quiet, strong, and sufficient for relaxed cruising.
- With an extra short shaft, approx. 8 to 9 km/h at full power and 6.5 to 7 km/h at about one-third power was reported.
- On a sailboat of approx. 700 kg, about 7 km/h was reported, with quick response and good maneuverability.
- On a Drascombe Lugger, a run time of approx. four to five hours was reported at about 6 km/h.
These are user experiences and not guaranteed performance. Results vary per boat and conditions.
