Sleipner SX80/185T External Stern Thruster 12/24V

SX80/185T-12V

SX80/185T-24V

SX80 is an efficient stern thruster designed for boats up to 48 feet with twin stern drives. The thruster provides 80-96 kg thrust, and its special cowls redirect water flow past the stern drives.

The unit is delivered fully assembled, wired, and sealed in a waterproof box and only requires a small hole in the boat's transom to attach power- and control cables.

Remote control is a popular accessory. See some of the important product and safety features below.

Sleipner's SX stern thrusters are the perfect choice for boats equipped with twin stern drives. The unit features special cowls that divert water flow past the stern drive legs, ensuring excellent performance. Thanks to its hydrodynamic shape, short flow channel, and optimal placement, the unit boasts minimal water resistance, allowing for high speeds without any perceptible loss.

Installation is a breeze, as the SX stern thruster is delivered preassembled, wired, and sealed in a waterproof box. Only a small hole in the boat's transom is required to attach the power and control cables. The streamlined design of the unit reduces noise emission by about 80%, thanks to its external placement of the engine, which also eliminates potential border cavitations.

Moreover, the external placement of the unit provides more efficient water cooling, resulting in a much longer duration per cycle compared to traditional bow and stern thrusters. With ignition protection as standard, installing the SX stern thruster in petrol-powered boats is safe. Trust Sleipner's SX stern thrusters for reliable and safe performance on the water.

Q-PROP™

The five-bladed Q-Prop™ reduces noise by up to 75% in tests, while maintaining or improving thrust efficiency.

• Noise reduction in typical installations: 20–40%
• Upgrade kits available for other models

INTELLIGENT POWER CONTROL

Patented system that reduces mechanical wear by minimizing direction-change delay and automatically stops the thruster in case of solenoid malfunction.

OVERHEAT PROTECTION

Automatic shutdown when high temperatures are detected (on/off models). Speed-controlled PRO models reduce power to maintain safe operating temperatures.

ANALOG

Color-coded analog signal cables with Plug & Play connectors ensure correct and easy installation.

GALVANIC SEPARATION

Submerged parts are electrically isolated from the onboard system to prevent galvanic corrosion and stray currents.

SEALED DRIVE LUBRICATION

Pre-filled gearleg with lifetime lubrication and advanced ceramic-carbon mechanical sealing for long-term water protection.

TWIN PROPELLERS

Two propellers deliver more thrust than single systems within the same tunnel diameter — ideal for compact, high-performance installations.
