S300-48v 160lb Electric Boat Trolling Motor With Speed Controller Saltwater, Diy on 2040-parts.com

Product Descriptions：

S300-48v has been designed for dinghies and sailboats up to 3 tons. Its 2100 watt input power is equivalent to a 7-HP petrol outboard.

S300 high-efficiency contributes to more thrust, greater speed and ultra-longer operating time and superior range.

S300 includes a power switch with IP56 waterproof grade, a speed controller and premium battery cables with a quick connector for safe and convenient appliance. 

S300 adopts unique brushless technology, which distinguish it from competition. For competition electric motor the rotation of motor is generated by sliding carbon brush, which gets worn out easily, consumes power and results heat. For S300 brushless electric motor, it is generated by electronic circuits, which is more reliable and stable. Comparing with competition electric motor, the advantage of S300 brushless motor is as below:
Efficiency values is significantly higher 30%-50%
Much higher torque values at lower battery currents
Longer service lives and less maintenance requirement 
Quieter power, cooler operation and less battery consumption
