Hobbywing SeaKing 3660 SL – Brushless Marine Motor

The Hobbywing SeaKing 3660 SL is a powerful, water-cooled brushless motor designed specifically for 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 reliable temperature control even under high loads.

Its robust construction, high-quality components and design for continuous marine operation ensure consistent, stable performance. In combination with the recommended SeaKing 90A V4 controller, this creates an optimally tuned drive system that offers high efficiency and long-lasting performance.

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