Hobbywing Seaking 3674SL 1900KV Motor V2 HW30419008

The Hobbywing Seaking 3674SL 1900KV Black Motor V2 (HW30419008) is a sensorless brushless motor for RC boats. It has a 1900KV rating, a four-pole design and is intended for 2–6S input voltage systems, with a no-load current of 4.3A.

A water-cooling jacket surrounds the motor to manage operating temperature during use. The motor uses a CNC aluminium case, high-temperature coils, a Kevlar-wrapped rotor, ultra-thin silicon steel sheets, a stainless steel shaft and ball bearings. Its modular construction allows the motor to be maintained by removing and servicing individual sections.

Suggested compatibility includes the Hobbywing Seaking 120A V4 ESC. When used as a matched system, the manufacturer states that this combination can support higher speeds and increased power output. The motor is suggested for boats up to 100cm in length, subject to the complete model setup and operating conditions.
