ePropulsion Navy 6.0 Evo 6 kW electric outboard motor including remote control

The ePropulsion Navy 6.0 Evo is a quiet 6 kW electric outboard motor for heavier boats and longer trips. The direct-drive system has no gear transmission and requires little maintenance. The remote control is included at Marinaut.

Key features

• Power: 6,000 W, 48 V and a maximum of 125 A.
• Thrust: 279 lbs.
• Comparison with combustion engine: ePropulsion cites a theoretical equivalent of 9.9 hp. Marinaut compares the practical sailing performance to approximately 10 hp of propulsion power up to 15 hp of thrust. Electric power, thrust, and the motor power of a combustion engine are not directly convertible.
• Hydrogeneration: while sailing, the rotating propeller can provide charging current to the battery.
• Closed liquid cooling: the cooling system does not use outside water.
• Noise: quiet due to the direct-drive motor.
• Starting: electric.
• Use: suitable for fresh and salt water.
• Trim and tilt positions: manually adjustable to 0°, 5°, 10°, 15°, 20°, 35°, 50°, 65°, and 80°.
• Steering: with manual control, the motor can rotate 360 degrees.
• Weight: 28.5 kg for the short shaft and 29.5 kg for the long shaft.

Which boats is the Navy 6.0 Evo suitable for?

The motor is used on sloops, RIBs, and sailboats, among others. As a practical selection guideline, the Navy 6.0 Evo is applied to bring boats up to approximately 5,400 kg to cruising speed and boats up to approximately 1,900 kg to hull speed. Actual performance depends on the hull shape, load, propeller, weather conditions, and battery installation. Also, view the explanation of electric boating.

On a light 4.5-meter RIB, a speed of approximately 26 kilometers per hour was measured. This is a practical example and not a guaranteed speed for every boat.

Operation and installation

The Navy 6.0 Evo Remote is connected to a monokabel steering control. For complete steering, a steering cable and steering wheel are also required. The available control options are:

• remote control for top-mount installation;
• side-mount control for Spirit Evo, Navy Evo, and Pod Drive Evo, with an additional cost of €149;
• dual Evo remote control for two motors;
• foldable tiller, item number NE-TC00-00.

The displays show the battery status and remaining sailing time, among other things. Switching between remote control and tiller later is possible.

Two propellers included

The motor comes with two three-blade propellers made of fiber-reinforced nylon:

• Low pitch, 340 × 216 mm: more pulling power and control for heavy boats and maneuvering; a lower top speed.
• High pitch, 320 × 274 mm: intended for lighter, streamlined boats where speed is more important.

An aluminum propeller is also available, item number N6-LU01-E0, with dimensions 12.6 × 8.7 inches. The thrust is between that of the low and high pitch propellers.

1,200 rpm	36.5	76.5%
1,300 rpm	35.0	79.3%
1,400 rpm	33.4	81.5%
1,500 rpm	32.3	83.4%
1,600 rpm	30.5	85.1%
1,700 rpm	29.2	86.5%

Shaft lengths and item numbers

• Short shaft: 64 cm, for a transom height of approximately 40 to 50 cm. Item number NE-6000-S1, EAN 6971312632026.
• Long shaft: 76.5 cm, for a transom height above 50 cm. Item number NE-6000-L1, EAN 6971312632033.

Measure the transom height from the top where the motor rests to the bottom of the boat. The required length may differ from that of a combustion engine. See the ePropulsion explanation of shaft lengths.

Battery and necessary components

Battery: not included. Choose a suitable 48 V battery and charging solution for the chosen installation.

• Battery: minimum 125 Ah. Recommended are an ePropulsion E175 LiFePO4 battery of 9 kWh or two E80 batteries. Suitable AGM and other LiFePO4 batteries are also possible.
• Installation: €995.
• For multiple batteries: battery cables and one ePropulsion E-Series Communication Terminator or E-Series Remote Battery Switch of 5 meters.
• Control: depending on the chosen version, a top or side-mount control, tiller, or dual remote control.

Sailing time and range are not given as a fixed value. These depend on the chosen battery capacity, speed, boat, load, and conditions.

Optional accessories

• ePropulsion wristband with kill switch. Free at Marinaut when specified with the order, worth €119.
• Anti-ventilation plate N6-AP00-E0: for performance improvement on light, fast-moving boats. Mounting 2 to 3 cm above the propeller and below the waterline.
• Steering rod for two motors: €245. Available in different lengths, including 700–900 mm. For two motors, the transom plate must be longer than 120 cm and the distance between the motors must be more than 60 cm.
• Dual control NE-DR00-00: control of two motors, together or separately. Includes 4.3-inch display and communication cables. EAN 6971312631920, price €795.

Navy 6.0 Evo or Haswing Armada?

Choose the ePropulsion Navy 6.0 Evo when silence, efficiency, hydrogeneration, and extensive control options are important.

Choose a Haswing Armada when a lower purchase price and simple, robust operation weigh more heavily than hydrogeneration and the extensive Evo functions.

Maintenance and business use

The direct-drive motor requires less periodic maintenance than a combustion engine. Check the anode and lubrication points according to the manual. Replace the transmission oil according to the ePropulsion maintenance schedule.

For commercial use, an electric drive may fall under a tax environmental scheme. Always check the current conditions and environmental list at RVO.

Transport on a boat trailer

Do not transport the motor in a trimmed position without extra support. This can damage the bracket, and this damage may not be covered by the warranty.
