SR100 185 retractable bow thruster 24v
$11,160.00
SR100/185T Retracting Thruster Kit (24V, 185mm) delivers strong, manufacturer-rated thrust for confident close-quarters maneuvering while retracting when stowed to help reduce drag. Designed for 185 mm tunnel integration and suitable for bow or stern setups, it’s an ideal upgrade for yachts in the typical 40–55 ft range that need reliable low-speed control in tight marinas.
SR100 185 retractable bow thruster 24v
This marine bow thruster is a retracting 24VDC thruster designed to deliver confident close-quarters control while minimizing drag when stowed. The unit is built around a direct mold-in concept with fast deployment/retraction and is positioned for typical vessel sizes in the 10–17 m (≈33–56 ft) range, depending on integration and handling goals.
side power SR100 retractable thruster kit
A key advantage is the retractable architecture: when not needed, the thruster retracts to reduce drag; when docking, it deploys quickly to provide lateral authority in wind/current. The platform is also described with Plug & Play S-Link™ two-way communication wiring and other integrated safety/feature items intended to support reliable marine duty use.

electric tunnel thruster
Positioned as an electric tunnel thruster solution with retracting geometry, SR100/185T-24V emphasizes thrust efficiency in a compact tunnel diameter through twin propellers and a feature set that supports reliability and system integration (e.g., S-Link™, sealed drive lubrication, galvanic separation).
What makes the SR100/185T a smart upgrade
- Reduced drag when stowed: retractable thrusters are positioned as a solution for minimizing drag when the unit is not in use.
- Strong published thrust in the 185 mm class: up to ~256 lbs (116 kg) at 24V for confident low-speed positioning.
- Built for mid-size vessels: typical integration is stated around 10–17 m (≈33–56 ft).
- Flexible as bow or stern: supports balanced maneuvering strategies depending on the yacht’s layout and use case.
- System-oriented platform: Plug & Play S-Link™ wiring and listed protection/feature items support cleaner integration planning and long-term reliability.
