Hobbywing Seaking 3660SL 2600Kv Black Motor V2 HW30419007

Hobbywing Seaking 3660SL 2600Kv Black Motor V2 (HW30419007) is a sensorless brushless motor for boats. It delivers a 2600Kv output and uses a four-pole design for smooth startup and operation. The motor is intended for 2–4S input voltage systems and includes a water cooling jacket to manage temperature during use.

The motor has a CNC aluminium case, high-temperature coils, a Kevlar-wrapped rotor, an ultra-thin silicon steel sheet and a stainless-steel shaft. Its modular construction supports maintenance, while the fitted bearings provide support at the front and rear of the motor. The manufacturer lists suggested compatibility with the Hobbywing SEAKING V4 90A ESC, where the pairing is intended to support increased speed and power output.

Features

This sensorless brushless boat motor has an 8.4A no-load current and a 5mm shaft diameter. Suggested boat applicability is for boats up to 80cm in length. The water cooling jacket is integrated into the motor housing, making cooling part of the installation rather than a separate accessory.
