Side-Power SRL100 Retractable Electric Bow Thruster, 12V — 100 kg On/Off Marine

SRL100 Retractable Thruster 90° Motor 12V | 220LB Thrust

The SRL100 Retractable Thruster 12V is a compact, high-performance 12V bow thruster designed for precision, reliability, and long-term durability. Developed by Sleipner (Side-Power), this model delivers exceptional maneuvering control while maintaining a streamlined hull profile, making it ideal for yachts and sailing vessels where internal tunnel space is limited.

With up to 100 kg (220 lb) of thrust, this system ensures powerful performance for docking, tight turns, and slow-speed maneuvers in any sea condition. The SRL100/185T combines ease of installation, advanced mechanical stability, and compact engineering for a truly dependable marine control solution.

Retractable Electric Bow Thruster

The retractable electric bow thruster system of the SRL100 is engineered for efficiency, safety, and simplicity. Its flange-mounted casing design allows for easy integration across various hull materials—fiberglass, aluminum, or steel—making it suitable for both custom builds and series production.

When activated, the thruster deploys quickly (within 3–5 seconds), providing instant thrust for precise maneuvering. When retracted, the unit sits flush with the hull, maintaining hydrodynamic efficiency and protecting the internal mechanism from marine growth or impact.

Built with a fast, high-torque actuator system, the SRL100 ensures smooth, reliable deployment and retraction. Its vertical motor orientation reduces stress from heavy seas and minimizes vibration compared to angled motor systems, ensuring stability and longevity even under demanding conditions.

The sealed gearleg design is permanently lubricated, eliminating messy maintenance and guaranteeing a lifetime of smooth, quiet operation.

Marine Bow Thruster

As a robust and compact marine bow thruster, the SRL100 provides unparalleled control and safety. It incorporates Side-Power’s trusted engineering principles, including shear pins on the hatch to prevent hull damage, IPC (Intelligent Power Control) for additional system protection, and galvanic isolation to prevent corrosion.

The system’s Plug & Play S-Link™ digital control network ensures seamless communication between the thruster, control panel, and accessories—offering intuitive operation and real-time system feedback.

Each component has been designed for reliability and minimal wear, with no moving parts during deployment, reducing the risk of jamming or failure. The Q-Prop™ propeller system enhances efficiency while further reducing noise, making this thruster ideal for vessels prioritizing both performance and comfort.
