Side-Power SRP80/185T Retractable Electric Bow Thruster, 24V — 80 kg Boat

SRP80/185T Retracting Proportional Thruster 24V | 176LB Thrust

The SRP80/185T Retracting Proportional Thruster 24V delivers high performance, silent operation, and precise maneuverability in a compact system. Designed and manufactured by Sleipner (Side-Power), this advanced 24V bow thruster provides complete control in all sea conditions and is the ideal choice for vessels that cannot accommodate a tunnel thruster.

Its innovative retractable mechanism allows it to extend only when needed and retract fully when not in use, preserving hull efficiency and aesthetics. With 80 kg (176 lb) of thrust, this unit ensures confident docking, reliable side movement, and full positional control, even under strong winds or current.

Retractable Electric Bow Thruster

The retractable electric bow thruster configuration provides the perfect balance between power and protection. When activated, the thruster deploys smoothly from the hull, generating immediate thrust with minimal turbulence. When retracted, it seals flush with the hull, eliminating drag and protecting the propellers from marine growth or damage.

The retractable system operates quietly thanks to twin composite propellers and a sealed gearleg that reduces vibration and noise. Additionally, a built-in pressure sensor automatically retracts the unit if the vessel exceeds safe operating speeds, while a thruster lockout system ensures it cannot be activated while partially retracted — maximizing safety and system reliability.

This design not only enhances performance but also reduces maintenance needs, making it ideal for owners who prioritize long-term dependability and low operating costs.

Boat Bow Thruster

Engineered for yachts and sailing vessels between 30 and 45 feet, this boat bow thruster provides responsive and proportional thrust for all docking and slow-speed maneuvers. Its proportional speed control allows the captain to choose exactly how much power to apply, ensuring smooth acceleration, gentle corrections, and total precision during approach and departure.

The S-Link™ two-way communication system simplifies installation, enabling plug-and-play integration with other Sleipner control panels and accessories. The horizontal motor mount minimizes space requirements, making it suitable for compact engine compartments or custom installations.

Because it’s powered by a 24V DC system, the SRP80/185T operates efficiently and quietly while reducing battery consumption — an advantage for modern vessels seeking high performance with minimal noise.
