Why Buy From Us

SLEIPNER SEP25/110S VARIABLE SPEED TUNNEL THRUSTER | 12V | 25KGF/55LBF THRUST | 2HP/1.5KW | SINGLE PROP

Whisper-quiet docking authority and proportional throttle precision for smaller vessels with tight structural constraints. The Sleipner Side-Power SEP25/110S is a premium 12V variable-speed tunnel thruster designed specifically for compact powerboats, center consoles, and day cruisers up to 24 feet. Delivering a dependable 25 kgf (55 lbf) of lateral thrust at its nominal 10.5V performance rating—and ramping up to a punchy 30 kgf (66 lbf) at a full 12V—this micro-sized powerhouse utilizes an ultra-low profile 110 mm (4.33-inch) tunnel diameter. Equipped with factory-standard S-Link™ Proportional Control, it replaces old-fashioned, blast-only "on/off" switches with smooth, variable speed joystick command.

The purpose-built 2 HP (1.5 kW) electric motor handles precision positioning effortlessly, giving small-boat owners commercial-grade docking confidence without overloading compact 12V battery banks.

Key Features:

  • True Proportional Power (S-Link™): Offers exact, metered variable speed control. Apply a gentle, quiet 10% nudge to smoothly hold position at the slip, or throttle up to 100% power to confidently fight crosswinds and tearing currents.

  • Micro 110mm (4.33'') Tunnel Profile: Sleipner's most compact tunnel profile. Specially engineered to easily fit into extremely narrow bows or shallow drafts where a traditional thruster setup would be physically impossible.

  • Maintenance-Free Sealed Gearleg: Features a factory-sealed gearhousing pre-filled with specialized lifetime gear oil. High-precision ceramic-on-carbon mechanical seals ensure absolute water tightness, completely eliminating regular gear oil changes.

  • Ultra-Quiet Single 5-Blade Q-Prop™: Outfitted with an aerodynamically skewed composite single propeller that cuts cavitation noise by up to 75% while squeezing maximum thrust and energy efficiency out of its compact housing.

  • Intelligent Power Control (IPC): Sleipner’s patented smart monitoring firmware protects the internal relays, preventing instant directional shifts and automatically cutting power if an electrical fault or overheating occurs.

  • Intelligent "Hold" Function: When paired with a proportional control panel, you can press the "Hold" button to lock in a specific thrust percentage—letting the thruster safely hold the boat against the dock single-handedly while you step off to secure lines.

  • Complete Galvanic Separation: The drive leg assembly features full insulation from the electric motor via specialized composite composite bushings, protecting underwater gear from harmful stray current and galvanic corrosion.

Specifications:

  • Part Number: SEP25/110S

  • Thrust Power: 25 kgf (55 lbf) at 10.5V / 30 kgf (66 lbf) at 12V

  • Motor Output: 1.5 kW (2.0 HP) at 10.5V

  • Typical Vessel Size: Up to 24 Feet (Up to 7.3 meters)

  • System Voltage: 12V DC

  • Tunnel Inner Diameter: 110 mm (4.33'')

  • Control System: S-Link™ Digital Bus (Variable Speed)

  • Propulsion Type: Single 5-Blade Q-Prop™

Pro Tip: Proportional thrusters run much longer and quieter than standard on/off models. By running the SEP25 at 30–40% power, you can comfortably hold your vessel against a dock or lock wall for extended periods without risking the rapid overheating common in old-school thrusters.
