Product Overview

Compact, efficient propulsion

The CubeMars SW17 is a 48 V underwater thruster that produces a maximum static bollard thrust of over 17 kgf and is rated for operation to about 30 metres. A streamlined nozzle reduces drag to improve propulsion efficiency and lower electrical load.

The precision-cast aluminium alloy housing resists corrosion and impact, while a two-stage sealing chamber and low-friction dynamic shaft seal block sand, dust and water for reliable, low-maintenance operation.
