Lewmar 250TT8.0Kw 11HP Gen2 24v Bow Thruster — Product description

Discover Superior Maneuverability with the Lewmar 250TT Gen2 Bow Thruster

Navigating tight marinas or handling crosswinds during docking can turn a relaxing day on the water into a stressful ordeal. That's where a reliable bow thruster like the Lewmar 250TT 8.0kW Gen2 steps in, delivering precise sideways control for mid-sized yachts and motorboats. This 24V tunnel thruster packs 140 kgf of thrust, making it a game-changer for vessels where every inch of precision matters. Owners rave about its whisper-quiet operation and effortless power, allowing even novice skippers to dock like pros.

What sets this Gen2 model apart? Lewmar engineers refined the design for sealed, maintenance-free performance—no hydraulic reservoirs means zero leaks or fluid checks. Imagine pushing off from a crowded pier with confidence, knowing the high-integrity seals and self-resetting thermal protection keep everything running smoothly, trip after trip.

Engineered for Peak Performance and Durability

  • Balanced Thrust in Both Directions: The innovative 5-blade propeller design ensures equal forward and reverse power, eliminating the guesswork in tight spots.
  • Silent and Efficient Gearing: Hardened spiral bevel gears transmit power with minimal noise and maximum efficiency, so you hear the waves, not the thruster.
  • Smart Electronics: The included Blue Box ICU safeguards the motor from overloads and misuse, with intuitive plug-and-play connections for hassle-free setup.
  • Spline-Driven Reliability: No fragile drive pins—just a robust spline system that keeps the prop spinning reliably under load.
  • Sleek Hydrodynamics: A low-profile hub minimizes drag, optimizing water flow for better overall boat performance.

Boat handlers appreciate how this thruster integrates seamlessly into 250mm tunnels, fitting popular hull designs without major modifications. Its bronze hub resists corrosion in saltwater environments, extending lifespan even in harsh marine conditions.
