Overview
The CubeMars SW7 underwater thruster delivers powerful and efficient propulsion for unmanned surface vessels (USVs), remotely operated vehicles (ROVs), electric surfboards, and handheld thrusters. Operating at 36V with a rated power of 360W, it generates a maximum bollard thrust of ≥7kgf and supports operation at depths of up to 30 meters. Crafted from high-strength aluminum alloy with precision casting, the SW7 offers excellent corrosion resistance and durability. Its streamlined hydrodynamic design, optional drag reduction cone, and advanced sealing technology ensure smooth performance and reliability in harsh aquatic environments.
