Side-Power SRP80/185T Retractable Electric Bow Thruster, 12V — 80 kg Boat

SRP80/185T Retracting Proportional Thruster 12V | 176LB Thrust

The SRP80/185T Retracting Proportional Thruster 12V is a compact, high-performance retractable electric bow thruster engineered by Side-Power to provide superior precision, silent operation, and energy efficiency. Designed for vessels that lack the space for a tunnel thruster, this unit combines the advantages of a retractable system with the control of proportional speed technology, offering smooth, reliable maneuvering for small and mid-sized yachts.

Delivering up to 80 kg (176 lb) of thrust, it ensures total command during docking, mooring, or navigating tight marinas — even under strong winds or currents. With its durable build and advanced electronics, the SRP80/185T sets the standard for efficiency and control in modern 12V bow thruster systems.

Boat Bow Thruster

Designed for performance and adaptability, this boat bow thruster features twin 5-blade composite propellers for optimal thrust and minimal vibration. Its proportional control capability allows captains to adjust power smoothly according to maneuvering needs — from gentle course corrections to full-power thrust.

Compact and flexible, the SRP80/185T uses a horizontal motor layout that simplifies installation in tight spaces, while the Plug & Play S-Link™ two-way communication system ensures intuitive setup and dependable connectivity between controls and motor.

This model can also function as a stern thruster, offering complete maneuverability at both ends of the vessel — a valuable advantage for operators seeking total control in any docking scenario.

Retractable Electric Bow Thruster

The retractable electric bow thruster design combines innovation, protection, and hydrodynamic efficiency. When activated, the thruster deploys vertically from the hull to deliver immediate thrust and precision control. When not in use, it retracts completely into the hull cavity, preserving the vessel’s sleek profile and significantly reducing drag.

This retractable system also prevents fouling and corrosion by shielding the propellers and housing when retracted — extending lifespan and minimizing maintenance. A pressure-sensing safety feature automatically retracts the unit when the vessel exceeds safe operating speeds, while a thruster lock-out system disables operation when partially deployed, ensuring total system safety.

With its fast-acting hydraulic hatch and minimal cut-out design, the SRP80/185T maintains a smooth exterior finish, delivering the perfect balance between performance, protection, and style.
