Sleipner SE170/250TC-24V Tunnel Thruster 24V

The SE170 is mechanically built like its larger brothers, making it the market leader in its size range, suitable for boats between 15-22m (50-70 feet). With its powerful 170-210 kgs of thrust, you get reliable thruster when you need it the most.

It is fitted either in a tunnel through the boat's bow or into a stern tunnel at the boat's stern using a stern thruster kit (sold separately).

Remote control is a popular accessory. Read more about the significant product features below.

FLEXIBLE INSTALLATION

Sleipner offers installation flexibility to work with the space you have. Our thruster models allow installation at any angle on the tunnel, tailored to fit any space available in your vessel.

Power supply

Powered by direct current.

FLEXIBLE COUPLING

Flexible coupling protects the product’s driveline by compensating for misalignment between the shafts of the electric motor and gearleg.

ANALOG

Sleipner analog signal cables with Plug & Play connectors are color-coded to match the wiring diagrams with high-quality connectors to ensure a correct installation.

OVERHEAT PROTECTION

Automatic detection of overheating of internal components. When an unsafe temperature is detected, the unit is automatically shut off to prevent overheating.

GALVANIC SEPARATION

Immersed parts exposed to seawater are galvanic isolated from the onboard electrical system, eliminating stray currents.

SEALED DRIVE LUBRICATION

The thruster gearleg is pre-filled for lifetime lubrication and sealed using a long-time mechanical seal with ceramic and carbon surfaces for ultimate security against water intrusion.

TWIN COUNTER-ROTATING PROPELLERS

Two counter-rotating propellers offer the most thrust at a good performance ratio in a minimal tunnel diameter. This system is used in our larger thrusters for maximum power. Our twin-counter thruster range is the favorite among leading boatbuilders in high-end yachts.

Q-PROP™

The Q-PROP™ has measured noise reductions of up to 75% in controlled environments. The five-bladed skew propeller reduces noise levels while maintaining exceptional efficiency. Some thruster models even see an increase in thrust power.

• The expected noise reduction in average installations: 20-40%
• Upgrade kits are available for most Sleipner thruster models with special adaptors

INTELLIGENT POWER CONTROL

Sleipner's patented intelligent power control provides a minimal delay between drive directions to reduce wear of the mechanical parts while monitoring solenoid functions. In the case of a solenoid lock-in, the thruster will automatically stop without extra user action or controlling the main switch.
