S400-48V 180LB Electric Boat Trolling Motor with Speed Controller 180 Pound Large Thrust Saltwater for DIY

S400-48v has been designed for dinghies and sailboats up to 4 tons. It is 2700 watt input power and 180lb thrust.S400 high-efficiency contributes to more thrust, greater speed and ultra-long operating time and superior range. S400 includes a power switch, a speed controller and premium battery cables with a quick connector for safe and convenient appliance.S400 adopts unique brushless technology, which distinguish it from competition.Other trolling motors use conventional commutator brushes which eventually wear out, consume additional power and generate unnecessary heat. S400 brushless electric motors use an electronic controller instead, providing these significant advantages: Efficiency values is significantly higher 30%~60% Much higher torque values at lower battery currents 5 times longer service life and no periodic maintenance required Less noise, cooler operation and reduced battery consumption Specifications Maximum thrust: 180 pound Input power:2700WMaximum efficiency:65% Volts:48VMaximum current:56AmpMaximum proper speed:1800RPMMaximum torque:12 N.MShaft: Stainless steel, standard length 36”(If need 10” or 42", leave message, no cost.
