Hobbywing Seaking 2850SL 3600Kv Motor V2 HW90070011

The Hobbywing Seaking 2850SL 3600Kv Black Motor V2 (part HW90070011) is a sensorless brushless motor for RC boats. It uses a 4-pole design and is rated at 3600Kv for 2-3S input voltage. A water-cooling jacket surrounds the motor to help manage operating temperature during use, while the modular construction allows access for maintenance.

The motor has a CNC aluminium case, high-temperature coils, a Kevlar-wrapped rotor, ultra-thin silicon steel laminations, a stainless steel shaft and bearings at the front and rear. Its sensorless brushless configuration keeps the motor design suited to installations where a sensor connection is not required. The manufacturer lists the Seaking 60A V4 ESC as the suggested ESC pairing, with the motor designed for integration with Seaking V4 electronics.

Suggested compatibility is with boats up to 60 cm in length. The black finish identifies this V2 motor within the Seaking range, while the 4 mm shaft diameter and compact 28 mm outside diameter provide useful information when checking the available space in a model. Review the figures below against your boat and drivetrain before installation.
