Sleipner E170 EVision 170kg Thrust Tunnel Bow/Stern Thruster 24V

The Sleipner E170 EVision redefines electric propulsion for serious sailors who dock in tight marinas or operate in challenging currents. This high-performance 24V electric tunnel thruster is purpose-built for 50–70 ft (15–22 m) vessels, delivering precise, powerful thrust where it matters most—without sacrificing efficiency or ease of installation.

Why the E170 EVision stands apart

• Industry-leading control and efficiency: A 6‑phase PMSM synchronous motor paired with an integrated inverter enables exceptionally smooth, variable speed control and optimized runtime for demanding docking scenarios.
• Significant weight reduction: Up to 50% lighter than previous Sleipner models, making installation simpler and reducing the load on your transom or bow system.
• Smart cooling for reliability: Active air cooling maintains peak performance during long, careful maneuvers in sun or heat—so you can rely on consistent thrust when visibility or wind is less than ideal.
• Quiet, precise hydraulics-free operation: A five-bladed skew propeller delivers clean, controllable thrust with minimal vibration or noise, ideal for night docking or busy harbors.
• Seamless integration: Designed to work with Sleipner’s S-Link control system, letting you integrate this thruster with your vessel’s existing electronics for intuitive control and automation.

Built for 50–70 ft (15–22 m) vessels

As a high-performance 24V electric tunnel thruster, the E170 EVision is purpose‑engineered to handle the demanding needs of mid‑sized motor yachts and sail-assisted powerboats. Its compact form fits a 250 mm tunnel, while delivering robust thrust and reliable operation in a variety of docking conditions.

Real-world benefits and use cases

• Docking precision in tight spaces: Variable speed control lets you feather the boat at inches-per-minute increments, reducing the risk of contact with pilings or other vessels.
• Enhanced maneuverability in wind and current: Subtle adjustments translate to confident lineups and safer berthing, even in gusty or tidal conditions.
• Quiet operations for sensitive environments: The low-noise, low-vibration design minimizes disruption on quieter canals or when guests are aboard.
• Future‑ready integration: S-Link compatibility means you can synchronize thruster commands with rudder, autopilot, or joystick systems for cohesive vessel control.

Who this is for

• Owners of yachts and sport boats in the 50–70 ft range who value precise, reliable propulsion for docking and close-quarters maneuvering.
• Marinas or boaters in crowded harbors seeking smooth, controlled thrust with minimal installation complexity.
• Vessel teams that want robust performance paired with a clear upgrade path through Sleipner’s trusted eVision technology.

Tips for installation and optimal performance

• Pair the E170 EVision with a compatible 24V electrical system and 충분한 battery capacity to meet the 395 A current draw during peak thrust.
• Plan for the 250 mm tunnel diameter in your hull when retrofitting, and coordinate with your existing S-Link ecosystem for seamless control.
• Schedule regular cooling checks during periods of intensive docking to ensure active air cooling remains unobstructed and effective.

With the Sleipner E170 EVision, you’re choosing a high-performance, lightweight, and intelligently integrated bow/stern thruster that meets the precise needs of modern 50–70 ft boats. It’s more than raw thrust—it’s reliable control, smarter cooling, and a smoother docking experience that translates to less stress on your crew and your vessel.
