SLEIPNER SEP80/185T-24V PROPORTIONAL TUNNEL THRUSTER | 24V | 80KG/176LB | TWIN PROPS
Take complete command of your vessel with throttle-exact docking precision and highly efficient 24V twin-propeller performance. The Sleipner Side-Power SEP80/185T-24V is a premium proportional tunnel thruster engineered for boats from 35 to 48 feet, delivering a dependable 80 kg (176 lbs) of lateral thrust. Equipped with factory-standard S-Link™ Proportional Control, this system completely replaces old-fashioned, full-blast "on/off" thrusters. Instead, you can gently dial in the exact percentage of power required via a throttle joystick, giving you whisper-quiet, pinpoint control over your bow or stern.
By utilizing a 24V architecture, this system ensures cool, highly efficient operation under sustained loads, drawing fewer amps and minimizing voltage drop over long cable runs compared to traditional 12V setups.
Key Features:
-
True Proportional Power (S-Link™): Offers exact, metered variable speed control. Apply a gentle, quiet 10% nudge to smoothly hold position alongside a finger pier, or throttle up to 100% power to confidently fight heavy crosswinds and tearing currents.
-
Twin Q-Prop™ Counter-Rotating Propellers: Outfitted with aerodynamically skewed, 5-blade composite twin propellers that maximize raw water-flow thrust through the 185mm tunnel while cutting cabin cavitation noise and hull vibration by up to 75%.
-
High-Efficiency 24V Architecture: Built for robust 24V marine electrical grids, this model manages sustained loads flawlessly and utilizes lighter, more flexible wiring runs during installation.
-
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 hold the boat against the dock single-handedly while you safely step off to handle mooring lines.
-
Galvanic Isolation Gearleg: The gear housing features a completely isolated propeller shaft, preventing electrochemical reactions and galvanic corrosion from spreading to vital internal drive components.

Pro Tip: Proportional thrusters run much longer and quieter than standard on/off models. By running the SEP80 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.
