Detailed description

The Sleipner SX80/185T 12V stern thruster is a standalone external unit designed for installation on the transom of vessels. This system is suitable for boats with limited internal space, shallow drafts, or standard 12V service battery systems. It is recommended for sailboats ranging from 10 to 15 meters (35 to 48 feet) in length.

Performance and Hydrodynamic Design

The SX80/185T 12V delivers 80 kg of thrust at 10.5V and can reach 96 kg at a peak load of 12V. Its motor provides 4.4 kW (5.9 HP) at 10.5V. The system features a tunnel with an internal diameter of 185 mm and uses twin Q-Prop™ five-blade contra-rotating propellers. This setup optimizes thrust density within the 185 mm tunnel while reducing cavitation noise and vibration by 20–40% in real-world installations and up to 75% in controlled environments.

Integrated Safety and Reliability

This thruster is equipped with patented Intelligent Power Control (IPC), a microprocessor-based system that minimizes mechanical wear and monitors solenoid performance. It includes overheat protection with automatic system shutdown in case of high temperatures. All submerged components are galvanically isolated from the vessel’s electrical system to eliminate stray currents and prevent corrosion. The gearcase lubrication system is factory-sealed for extended service life, featuring ceramic and carbon mechanical seals. The Sleipner SX80/185T 12V is certified to ISO 8846 (ignition protection) and CE, making it suitable for installation on gasoline-powered vessels or near fuel ventilation ducts. Optional covers are available for optimal performance with twin stern drives.

Expert opinion

« Sleipner SX80/185T 12V stern thruster: external option for tight spaces »

The Sleipner SX80/185T 12V stern thruster stands out for its external pod design, a strategic solution for vessels where integrating a traditional tunnel thruster is complex or impossible. It is particularly suited to boats with limited draft or those requiring preservation of internal volume, such as sailboats or motor vessels with dense aft layouts. Installation is simplified by its self-contained and pre-assembled nature, requiring minimal drilling of the transom for power and control cable routing.

Its ability to operate on a 12V DC system makes it a relevant choice for vessels equipped with standard service batteries without requiring complex conversion. The Q-Prop™ contra-rotating propeller technology is a key feature, reducing noise and vibrations perceived on board (by 20 to 40% in real-world installations and up to 75% in controlled environments), which enhances comfort during docking manoeuvres. The ISO 8846 certification for ignition protection broadens its application to gasoline-powered boats, offering increased safety. During installation, it is critical to validate sizing, voltage, and precise location with a professional to ensure optimal performance and reliable system integration, particularly for control accessories and electrical power.
