Product Overview

A complete propulsion kit

The CubeMars W30 is a complete underwater thruster kit built around a W30 KV320 brushless motor, delivering a maximum forward thrust of up to 7.7 kgf and around 5.8 kgf in reverse. It is rated for operation to about 200 metres and designed for easy integration into marine robots and electric surfboards.

The kit includes the motor, a matched pair of CW and CCW propellers, a W30-6S-45A ESC and a shroud. Advanced anti-corrosion treatment and a compact, lightweight structure give stable performance in harsh saltwater environments.
