Side-Power SRL80 Retractable Electric Bow Thruster, 12V — 80 kg On/Off Marine

SRL80 Retractable Thruster 90° Motor 12V | 176LB Thrust

The SRL80 Retractable Thruster 12V by Sleipner (Side-Power) is a compact and efficient 12V bow thruster designed for yachts and sailing vessels requiring precision control, low noise, and easy installation. This model combines advanced engineering, durable materials, and a smart retractable mechanism — offering the perfect balance of performance, safety, and reliability for marine maneuvering.

With 80 kg (176 lb) of thrust and a space-saving design, the SRL80 ensures superior handling during docking, mooring, or navigating narrow marinas. Built with Sleipner’s strict safety and quality standards, it delivers professional-grade performance for vessels up to 48 feet.

Retractable Electric Bow Thruster

The retractable electric bow thruster system offers the perfect combination of efficiency, protection, and simplicity. The flange-mounted casing allows the thruster to be securely bolted onto the hull base, simplifying installation on various hull materials — including fiberglass, aluminum, and steel. This configuration eliminates the need for laminating work, making it ideal for both new builds and production boats.

Equipped with a fast, high-torque actuator, the SRL80 deploys or retracts in approximately 3–5 seconds, providing instant response when maneuvering. Once retracted, the unit fits flush against the hull, minimizing drag and preventing marine growth on the propellers and moving parts.

The vertical motor installation reduces mechanical stress and impact during heavy seas, while the sealed drive system ensures lifetime lubrication and maintenance-free operation. The entire underwater mechanism consists of only a few, robust components — each engineered for strength, stability, and long-term performance.

Marine Bow Thruster

As a dependable marine bow thruster, the SRL80 offers Sleipner’s proven reliability and intelligent safety systems. The Plug & Play S-Link™ digital control system provides two-way communication between the motor, control panels, and accessories, enabling precise feedback and quick diagnostics.

Safety remains a central part of the design. The shear pins on the hatch prevent hull damage under excessive force, while the IPC (Intelligent Power Control) feature safeguards the system against overload, overheating, or electrical faults.

With its twin Q-Prop™ propellers, the SRL80 ensures high thrust efficiency with minimal vibration and noise. The galvanic separation and high-quality materials provide resistance to corrosion, even in harsh saltwater environments, extending the system’s lifespan and reliability.
