Lewmar 140TT 2.2kw Gen. 2 Bow Thruster -12V

Master Precision Docking with the Lewmar 140TT Gen 2 Bow Thruster

Picture this: you're approaching a tight marina slip with crosswinds pushing your boat off course and currents tugging at the bow. What was once a stressful ordeal becomes a confident maneuver with the Lewmar 140TT 2.2kW Gen 2 Bow Thruster. Designed for boats where every inch counts, this 12V tunnel thruster delivers balanced power forward and reverse, turning novice captains into docking pros.

Unlike older models that struggle with uneven thrust, the Gen 2 series features a revolutionary five-blade propeller that spins with hydrodynamic perfection. It slices through water efficiently, minimizing cavitation and noise while maximizing control. Boaters rave about its whisper-quiet operation—perfect for early morning departures without waking the harbor.

Standout Features That Set It Apart

This thruster isn't just another piece of gear; it's engineered for real-world reliability on the water. Here's what makes the Lewmar 140TT a game-changer:

• Maintenance-Free Design: Say goodbye to hydraulic reservoirs, leaks, or constant upkeep. The cassette seal and spline-driven prop eliminate anodes and drive pins, keeping things simple and sealed tight.
• Equal Thrust in Both Directions: The high-performance five-blade prop ensures identical power port and starboard, giving you pinpoint control even in tricky conditions.
• Smart Electronics: Built-in blue box safeguards the motor from overloads and misuse, with self-resetting thermal protection that keeps you operational without fuss.
• Quiet and Efficient Gearing: Hardened spiral bevel gears transmit power smoothly, reducing vibration and extending gear life under heavy use.
• Seamless Installation: Plug-and-play connections for switches and a low-profile hub promote smooth water flow, preventing drag when underway.
• Durable Construction: Thick stainless steel sections wrapped in a sleek hydrodynamic shell stand up to saltwater corrosion and impacts.

Whether you're retrofitting a mid-size cruiser or outfitting a new sportfisher, this thruster integrates effortlessly with joystick or touch panel controls for intuitive handling.
