    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.

    OVERHEAT PROTECTION

    When high temperatures are detected, On/off thrusters are automatically shut off to prevent overheating. PRO™ thrusters with speed control provide extended run-time by derating power to maintain temperature within safe levels.

    FLEXIBLE COUPLING

    Flexible coupling protects the product’s driveline by compensating for minor misalignments between the shafts of the thruster motor and gearleg.

    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.

Item code: SE300/300TC

SE300 is a powerful thruster with 300-340 kg thrust. Suitable for boats between 72-100 feet/ 22-30 meters, depending on weight and windage area. Can be mounted in the bow and stern.

The thruster offers great installation flexibility as it can be mounted at any angle on the tunnel. Additionally, the electric motor can be rotated 90 degrees on the motor bracket. 

It is galvanically isolated and features Sleipner's patented IPC technology for intelligent power control and safety. See more of the product features below.

Sleipner's tunnel thrusters are the world's top-selling thrusters resulting from over 35 years of development. Over the years, our tunnel thrusters have been installed in over 350,000 boats worldwide.
 

Bow and stern thruster

They are fitted either in a tunnel through the boat's bow or into a stern tunnel at the boat's stern. Available as standard version (on/off), PRO™ version (variable speed control), and IP PRO™ version (with ignition protection and variable speed control), extending from 20 kg to 300 kg of thrust.

Sleipner's stern tunnels are designed with solid and durable fiberglass to enhance the thruster's performance and are installed effortlessly in the boat's transom. Additional cowls (sold separately) allow installation in boats with shallow drafts or obstructions on the stern.

The electric motors, solenoids, patented IPC control system, and mechanical parts of the propulsion system are all custom designed and built - utilizing the extensive experience gained through years of leadership in the global thruster market.

 

Docking has never been easier

Our PRO™ thruster models are equipped with speed control, giving you full variable control of the thruster. The speed control is more intuitive for you as a boater and makes for a quieter and more relaxed maneuver. If you install a dual thruster system (bow and stern), you get the revolutionary hold function, pinning the boat to the pier while docking.

Ignition protection

We offer ignition-protected thruster models to provide a reliable and safe installation in locations where the thruster motor may be exposed to water or gasoline fumes.

Our IP models have a hermetically sealed composite housing around all electric parts. 

An additional advantage is that electric parts that could obtain water damage are also covered and protected, making these thrusters the ideal choice for stern thruster installations where ensuring that the thruster will always remain dry is difficult. The IP versions have all the benefits and proven reliability of our standard tunnel thrusters.
