Proportional Retracting Thruster Retro Kit
The Lewmar Proportional Retracting Thruster Retro Kit lets you upgrade your vessel to a fully retractable, variable-speed thruster system. Combining Lewmar’s efficient brushless proportional motor technology with a retracting mechanism that stores cleanly inside the hull, it delivers smooth, quiet and precise manoeuvring without adding drag underway. Built for retrofit compatibility with existing Lewmar installations, it offers deeper immersion, better thrust efficiency and premium low-speed control for performance-focused yachts.

Smooth, Variable-Speed Thrust for Superior Control
Powered by Lewmar’s advanced proportional brushless motor systems, the retrofitted thruster provides infinitely adjustable thrust levels for delicate, highly controlled manoeuvring. Proportional brushless systems are chosen for their efficiency, long life, and the ability to deliver refined throttle response ideal for precision docking.
Durable, Maintenance-Free Brushless Design
The proportional motor range is built using brushless digital DC technology, offering zero brush wear and extended operating life. The system is engineered to withstand continuous operation with no maintenance requirements beyond vessel checks.
Quiet Operation with Better Immersion Depth
Retracting thrusters achieve deeper immersion when deployed compared to fixed tunnels, resulting in quieter, more efficient thrust. Because retracting units can be mounted further forward, they also provide improved turning leverage and higher manoeuvring authority.
Retrofit-Ready for Existing Lewmar Installations
Designed to integrate seamlessly with current Lewmar thruster systems, this retro kit is compatible with Lewmar’s proportional controllers and can be adapted to existing installations. Retrofit capability is a key benefit of Lewmar’s proportional motor range, allowing owners to upgrade without a full system replacement.
