Hobbywing Seaking 3660SL 3400Kv Motor V2 HW30419006

The Hobbywing Seaking 3660SL 3400Kv Black Motor V2 (HW30419006) is a sensorless brushless motor for boats, with a black finish and water-cooling jacket. Its 3400KV rating is intended for 2–4S input voltage, while the four-pole design provides smooth startup characteristics for marine radio-controlled models.

The motor uses a CNC aluminium case, high-temperature coils, a Kevlar-wrapped rotor, an ultra-thin silicon steel sheet and a stainless-steel shaft. Bearings are fitted at the front and rear, and the modular construction allows the motor to be opened for maintenance. The water-cooling jacket is designed to carry cooling water around the motor during operation.

Suggested compatibility includes Hobbywing’s Seaking 90A V4 ESC, with the manufacturer describing the motor and ESC as suitable for integration together. The stated boat application is for models up to 80 cm in length. Check the complete power system and available installation space before fitting.
