CubeMars SW17 Underwater Thruster

Product Description

The CubeMars SW17 underwater thruster is a high-thrust propulsion system engineered specifically for shallow-diving unmanned surface vessels (USVs) and handheld diver propulsion vehicles (DPVs).

Constructed with precision-cast aluminum alloy, it features a dual-chamber independent sealing structure and a low-friction dynamic shaft seal. Internally filled with high-thermal-conductivity potting material, the thruster achieves enhanced heat dissipation—enabling reliable operation in water depths from 0 to 30 meters. With a rated voltage of 48 V, it delivers a maximum static thrust of ≥17 kgf, making it ideal for USVs, electric surfboards, handheld propulsion units, and other applications demanding high power in compact form.
