Engineered for Maximum Efficiency and Reliability

Every Sleipner thruster is designed with performance, efficiency, and longevity in mind. Key design features include:

Hydrodynamic gearlegs that minimize drag and resistance, maximizing overall system efficiency
Clean, streamlined housing design to optimize water flow and reduce turbulence
Optimized tunnel and propeller geometry for maximum thrust output
5-blade bronze Q-Prop™ propellers for:
- Reduced noise and vibration
- Increased efficiency and thrust
- Lower risk of cavitation
- Smooth, predictable maneuvering

Comprehensive Thruster Solutions for Commercial Applications

Sleipner offers one of the industry’s most complete ranges of commercial thrusters, covering everything from compact workboats to large commercial vessels:

Hydraulic Thrusters:
Available in tunnel diameters from 7¼” to 29”, delivering 220 lbs up to 4,800 lbs of thrust for precise, powerful maneuverability.
AC Thrusters:
Offered in 10” through 29” tunnel sizes, providing dependable performance for larger vessels and continuous-duty applications. A new Permament Magnet motor option will be available for the larger sizes (700 kg thrust/16" (410 mm) tunnel sizes and up.
DC Thrusters (E-Series)
Proportional 24V and 48V DC thrusters in 8½”–12” tunnel sizes, delivering up to 770 lbs of thrust, with runtime limited only by onboard battery capacity. Brushless Sleipner-engineered motors, lightweight bronze gearlegs with composite Q-Props, ignition protected, splashproof, and joystick-ready via S-Link CANbus.
Commercial Certification:
All commercial-grade thrusters are DNV approved, meeting strict international standards for safety, reliability, and performance.
Service-Friendly Design
Larger models feature optional in-water gear oil change capability, reducing downtime and simplifying routine maintenance.
