Hobbywing SeaKing 2040 SL V2 – Brushless Marine Motor

The Hobbywing SeaKing 2040 SL V2 is a compact, powerful brushless motor that has been specially developed for use in RC boats. Thanks to its integrated water cooling jacket with internal circulation channel, the motor remains reliably cool even under prolonged load and delivers consistent performance.

In combination with the optimally matched SeaKing 30A V4 ESC, the 2040 SL V2 delivers particularly harmonious power output and high efficiency. Its robust construction and precise bearings ensure smooth running and durability – even under demanding conditions.

The motor is ideal for model boats up to 45 cm in length and offers an excellent balance of weight, speed and thermal stability. This makes it the perfect choice for ambitious RC boaters who value a reliable, marine-grade drive system.
