Seaking 4685SL 900kV brushless water-cooled

Hobbywing Seaking 4685SL 900kV V2 brushless motor for boats

Specially developed for large model boats with high performance and low operating temperatures thanks to efficient heat dissipation.
Constructed with a high-strength CNC aluminium housing, high-quality bearings, ultra-thin silicon steel laminations, high-temperature copper wire, high-temperature rotor and high-strength output shaft. Each material has been carefully selected to ensure that the motor delivers long-lasting and stable performance.

The motor's water cooling jacket features a highly efficient internal circulation design with external cooling fins. There are ventilation holes on the front and rear end caps and a blade-shaped fan.
This design not only enables fast motor cooling, but also ensures stable performance and consistent power output during prolonged high power and high torque operation.

Combined with the SeaKing V4 controllers, the motor offers smoother control, quicker response and a more exhilarating riding experience!
