Overview
The CubeMars SW17 Underwater Thruster delivers powerful and efficient propulsion for unmanned surface vehicles (USVs), electric surfboards, and handheld thrusters. Operating at 48V with 870W rated power and generating maximum bollard thrust ≥17 kgf, it is engineered for high-performance navigation up to 30 meters depth. Its aluminum alloy precision-cast shell ensures durability and corrosion resistance, while the low-resistance dynamic seal and two-stage sealing chamber provide reliable waterproof protection. The streamlined nozzle and customizable drag reduction cone optimize hydrodynamics for smooth movement in high-speed conditions.
