Hobbywing SeaKing 3660 SL – Brushless Marine Motor

The Hobbywing SeaKing 3660 SL is a powerful, water-cooled brushless motor designed for demanding use in RC boats. Like all models in the SeaKing SL series, it features an integrated water cooling jacket with internal circulation channel, which ensures that the motor is reliably cooled even under high loads and delivers consistently stable performance.

High-quality workmanship, precise bearings and a design optimised for marine use make the 3660 SL a reliable choice for high-performance boat models. In combination with the recommended SeaKing 90A V4 controller, the result is a perfectly matched, efficient and durable drive system.

With its high speed reserve, the SeaKing 3660 SL is ideal for RC boats up to 80 cm in length that require a powerful, thermally stable and durable drive system.
