CubeMars SW12 Underwater Thruster

Product Description

The CubeMars SW12 underwater thruster is a high-efficiency propulsion unit designed specifically for light-duty underwater platforms such as surface/semi-submersible unmanned surface vessels (USVs), handheld diver propulsion vehicles (DPVs), and electric surfboards.

Featuring a high-strength aluminum alloy housing, a dual-chamber independent sealing structure, and a low-friction dynamic shaft seal system, the SW12 is filled internally with high-thermal-conductivity material and leverages direct water cooling for efficient thermal management. It operates reliably at depths up to approximately 30 meters and delivers a static thrust of ≥12 kgf.

This thruster is ideal for applications demanding an optimal balance of compact size, lightweight design, and high thrust—such as USVs, handheld propulsion devices, and electric hydrofoil boards.
