QSR – Retractable Thrusters

The QSR retractable thrusters can be both DC electric and hydraulic. Designed to give minimal hydrodynamic turbulences (especially in sailboats applications) the QSR retractable thrusters take advantage of the same technology applied to the other ranges. In DC version they can be provided in ON/OFF configuration.
