Overview

The ePropulsion Navy 6 is a 6kW/9.9hp electric outboard that's a great choice for sailboats, dinghies, and bass boats. The Navy 6 Evo can be controlled with a tiller or remote throttle and is powered by an external battery, typically two ePropulsion E60 batteries or one E163.

Controls

The Navy 6 can be used with a tiller, top mount remote control, side mount remote control, or dual mount remote control. It is easy to switch between controls for the Navy 6 Evo if you change your mind in the future. The Navy 6 Evo can be hooked up to a standard teleflex steering system if you aren't planning to use a tiller.

Batteries

We recommend using two ePropulsion E60 batteries or one E163 battery with the ePropulsion Navy 6 Evo. It is not possible to power the Navy 6 with one E60. Using two E60 batteries with a Navy 6 Evo, customers can expect about one hour of run time at full power and about two hours of run time at half power. Using one E163 Battery, customers can expect about one hours and 20 minutes of run time at full power and about two hours and 40 minutes of run time at half power. Actual run time depends on a number of factors including the weight and shape of the hull, number of people in the boat and sea state. 

While we recommend using the Navy 6 Evo with an ePropulsion E Series Battery, it is possible to use the Navy 6 outboard with a third party battery. There are a number of factors to consider if you're thinking about using a third party ePropulsion battery; we'd recommend reading out blog post on using third party batteries with ePropulsion motors. Some factors to consider are:

Voltage. The Navy 6 Evo runs on 48 volts. You can use more than one 48v battery if you wire them in parallel. If you're planning to use more than one third party battery with your ePropulsion Navy 6 Evo, you may be able to use two 24v batteries or four 12v batteries if you wire them in series, but the voltage must add up to 48v.

Continuous power output. It's important that the continuous power output of the third party battery can meet the power demand of the Navy 6 Evo. The specification that you're looking for here is the continuous discharge rate of the battery; you need to make sure that the battery's continuous power output is greater than or equal to the power demand of the motor, which is 125A for the Navy 6 Evo.

IP rating. ePropulsion E Series Batteries are IP67 rated, which means that the E60 and E163 are completely protected from dust and are protected against water for up to 30 minutes at a depth of one meter. If you do decide to use a third party battery with your ePropulsion Navy 6, it's best practice that this battery also be rated IP67. 

Built in Battery Management System (BMS). A built in BMS is a very important safety feature for batteries for electric outboards. Not only does the BMS monitor the battery for safety reasons, but it optimizes battery performance and longevity. It's important for safety reasons that any third party ePropulsion battery has a built in BMS.

Bluetooth/state of charge (SOC) monitoring. If you decide to use a third party battery with the Navy 6 Evo, you won't have a data cable that connects the motor the the battery. You motor should still be able to tell you SOC, but having an additional SOC monitoring method is helpful during use and when your battery isn't connected to your electric boat motor. Most high quality batteries have a Bluetooth feature, which allows you to monitor the SOC of your third party ePropulsion battery from your phone.

Cables & Wiring 

The ePropulsion Navy 6 has two power cables that come out of the motor (a positive and negative that are each about 6ft long) as well as a data cable that is about 15ft long. Customers who are using a side mount remote control with the Navy 6 Evo must purchase an additional data cable (one cable runs from the motor to the battery, the other runs from the motor to the throttle). Customers who are using the top mount control may purchase the same cable or choose to connect their top mount throttle to their Navy 6 via Bluetooth. Customers who are using the Evo Tiller do not need to purchase an additional data cable as there is a cable built into the Evo Tiller that connects to the Navy 6 Evo. 

Customers who are using the Navy 6 with an E Series battery/batteries placed more than 6ft from the motor will need to extend their power cables by purchasing an ePropulsion Bus Bar 150A as well as an E Battery Bridging Cable. The E Battery Bridging Cable is available in 0.15m, 0.45m, 1.5m and 5m lengths. The power cables will run from the motor to the bus bar, and the E Battery Bridging Cable will run from the bus bar to the E Series battery.

Customers who are using the ePropulsion Navy 6 with two ePropulsion E Series Batteries need to purchase additional cabling to connect the two batteries. You'll need an E Battery Bridging Cable (sold in sets, includes positive and negative cables) and a Battery Communication Cable Kit.

It is recommended that customers who are using a third party battery to power the Navy 6 Evo purchase a third party battery kit, which includes one E Battery Output Cable (1.5m) and one ePropulsion Bus Bar 150A. This kit allows you to connect an ePropulsion Navy 6 Evo to a third party battery without cutting the motor cables and crimping on new ring terminals. Alternatively, you can cut the connectors off of the motor power cables and crimp on new ring terminals. We do not recommend doing so, as any issues that arise that correlate to a bad crimp would not be covered under warranty. To use this kit, you'll connect the power cables from the Navy 6 Evo to the bus bar, then connect one end of the E Battery Output Cable to the bus bar, then connect the other end to your third party ePropulsion battery.
