Side-Power SRP100/185T Retractable Electric Bow Thruster, 12V — 100 kg Marine

SRP100/185T RETRACTING PROPORT THRUSTER 12V, 100Kg/220LB

The SRP100/185T Retracting Proportional Thruster 12V is a compact yet powerful 12V bow thruster engineered to deliver exceptional control, silent performance, and reliable thrust. Designed by Side-Power, a trusted name in marine maneuvering systems, this model combines the precision of proportional speed control with the efficiency of a retractable configuration—making it ideal for yachts and sailing vessels where internal tunnel space is limited.

With up to 100 kg (220 lb) of thrust, it provides smooth, responsive handling during docking, anchoring, or close-quarter maneuvers, even in challenging conditions.

Retractable Electric Bow Thruster

This retractable electric bow thruster extends vertically from the hull when activated, providing immediate directional power and precise control. When not in use, it retracts completely into the hull, maintaining a clean hydrodynamic profile and minimizing drag.

The design ensures that the thruster remains protected from marine growth and corrosion, extending its operational lifespan. Thanks to its proportional control system, the SRP100 allows captains to adjust thrust intensity for fine movements, reducing energy consumption while improving responsiveness and safety in confined spaces.

Its horizontal motor mount and compact assembly make installation easier, even in smaller engine rooms. The unit can also function as a stern thruster, giving full control over vessel positioning during docking or mooring operations.

Marine Bow Thruster

Built to endure demanding conditions, this marine bow thruster features a sealed gearleg system that requires no oil fill during installation, reducing maintenance and ensuring smooth operation. The composite propellers and streamlined housing minimize turbulence and vibration, delivering quiet and efficient thrust performance.

Advanced safety measures—such as an overheat protection switch, flexible coupling between motor and gearleg, and self-locking high-pressure solenoids—extend system reliability and service life. Combined with corrosion-resistant materials and a two-year limited warranty, the SRP100 offers lasting value for any yacht owner.
