Hobbywing SeaKing 3674 SL V2 – Brushless Marine Motor

The Hobbywing SeaKing 3674 SL V2 is a particularly powerful, water-cooled brushless motor for large RC boats. Like all models in the SeaKing SL V2 series, it has an integrated water cooling jacket with an internal circulation channel, which reliably maintains the motor at its optimum operating temperature even under prolonged load.

Thanks to its robust construction, precise bearings and design optimised for continuous maritime use, the 3674 SL V2 delivers consistently stable performance. In combination with the recommended SeaKing 120A V4 controller, it creates a powerful and optimally tuned drive system that guarantees high efficiency and a long service life.

With its strong torque development, the SeaKing 3674 SL V2 is ideal for RC boats up to 100 cm in length that require a particularly resilient, thermally stable and powerful drive system.
