Operating voltage

Detailed description

The Sleipner SX100/185T 12V external stern thruster is a manoeuvring solution designed for vessels from 12 to 17 metres (39 to 55 feet), particularly those with twin drives. This external system eliminates the need for major structural work on the hull, as it is supplied fully assembled, wired, and sealed in a watertight housing. Only a small hole in the transom is required for power and control cables.

Performance and integrated technologies

This thruster delivers a thrust of 100 kg (220 lbs) at 10.5V and 116 kg (256 lbs) at 12V thanks to its dual-propeller system, optimizing power within an internal tunnel diameter of 185 mm. Powered by 12V DC, it provides 6.3 kW (8.4 hp) at 10.5VDC. The Q-PROP™ technology features an asymmetric five-blade propeller, reducing operational noise by 20 to 40% in real conditions and up to 75% in controlled tests, without compromising thrust performance.

Safety and durability

The Intelligent Power Control (IPC) system minimizes the delay between direction changes, reduces mechanical wear, and monitors solenoids. In case of solenoid blockage or prolonged continuous signal, the thruster automatically stops, enhancing safety and system longevity. Overheat protection ensures the system shuts down automatically before any damage occurs. The galvanic isolation of submerged parts prevents corrosion. The strut lubrication system is sealed for life with ceramic and carbon mechanical seals for enhanced watertightness. Its hydrodynamic design reduces water resistance, even at high speeds. Watertight and ignition-protected, its robust GRP housing allows secure installation, including on gasoline-powered boats. Analog control is facilitated by Sleipner Plug & Play connectors. Maintenance is possible when the boat is ashore, thanks to a replaceable O-ring.

Expert opinion

«
Sleipner SX100/185T 12V external stern thruster: no-compromise maneuvering
»

The Sleipner SX100/185T 12V is positioned as a strategic solution for boat owners of 12 to 17 meters, particularly those whose internal configuration (type of propulsion, layout) makes installing a traditional stern thruster complex or even impossible.

Its external, pre-assembled, and watertight mounting significantly simplifies the integration process. Only minimal drilling in the transom is required for cable passages, avoiding heavy and costly lamination work. This approach not only reduces vessel downtime but also mitigates risks associated with structural interventions.

The dual-propeller technology delivers effective thrust of 100 kg at 10.5V and 116 kg at 12V, while the Q-PROP™ system significantly reduces noise pollution, a notable advantage for onboard comfort. Robustness is ensured by a GRP housing resistant to corrosion and galvanic isolation of submerged components, extending the device's lifespan in harsh marine environments. The Intelligent Power Control (IPC) system adds an additional layer of safety and reliability by protecting the motor against overloads and solenoid malfunctions.

A notable practical advantage is the ability to perform maintenance and replace the O-ring seal when the boat is ashore, without requiring complex disassembly of the main unit. It is crucial to validate sizing, tension, and accessories (such as optional cowls for twin-skeg boats) with an expert to ensure optimal performance and seamless integration with the vessel's electrical system.

Frequently Asked Questions

Need help? Contact us

What is the thrust power of the Sleipner SX100/185T 24V stern thruster?

The Sleipner SX100/185T 24V stern thruster delivers a nominal thrust of 116 kg at 24V. At 21V, its thrust is 100 kg.

For which sailboat size is the SX100/185T 24V stern thruster recommended?

The Sleipner SX100/185T 24V stern thruster is ideally suited for vessels between 12 and 17 meters (or 35 and 55 feet).

Can the SX100/185T 24V bow thruster be controlled with a variable speed system?

Yes, the SX100/185T 24V thruster is compatible with Sleipner’s PRO™ technology. This option provides variable-speed control for smoother, quieter, and more precise maneuvers. It also includes a hold function for twin systems, allowing the boat to be held gently against the dock with a single button press.

What is the Q-PROP technology used in this thruster?

The Q-PROP technology is a five-blade, skewed propeller system designed to reduce propeller operating noise by 20 to 40% in real-world installations, and up to 75% in controlled tests. This technology maintains or improves thrust performance while providing quieter operation.

Is it possible to add a remote control to operate the SX100/185T 24V thruster?

Yes, it is possible to add a remote control system for the SX100/185T 24V thruster. This allows you to operate the system remotely, making docking manoeuvres easier, especially with a reduced crew.

What are the built-in protections for the Sleipner SX100/185T 24V thruster?

The Sleipner SX100/185T 24V thruster integrates multiple protection systems:

Overheat protection: Automatically detects high internal temperatures and shuts down the system before damage occurs. Galvanic isolation: All underwater components are electrically isolated from the onboard system to eliminate stray currents and prevent galvanic corrosion. Smart power control: Minimizes mechanical wear by ensuring minimal delay between direction changes and monitoring solenoid performance. If a solenoid is blocked, the thruster automatically shuts down. Safe start-up: Control panels require a two-button activation to prevent accidental starts.

Does the SX100/185T 24V thruster require specific lubrication?

Yes, the SX100/185T 24V thruster uses a gravity-fed lubrication system. A separate oil tank, located above the waterline, feeds the lower unit by gravity. This creates positive pressure for effective water sealing and makes oil changes easier. Additionally, it features factory-sealed lifetime lubrication with long-life ceramic and carbon seals.
