Lewmar 140TT — 12V Bow Thruster Kit, 2.0kW
Take the stress out of tight marina maneuvers. The Lewmar 140TT is a 2.0kW, 12-volt bow thruster kit engineered for confident docking and departure in any wind or current condition. Whether you're backing into a slip solo or navigating a crowded fairway, this thruster gives you precise lateral control at the push of a button.
Key Features
- Completely sealed, reservoir-free design — no hydraulic fluid, no leaks, no routine maintenance
- High-integrity motor seal for long-term reliability in harsh marine environments
- Black box electronics module protects the motor from overload and voltage spikes
- Hardened spiral bevel gears deliver maximum efficiency and whisper-quiet power transfer
- Self-resetting thermal protection on all motors — no manual reset required after overload
- Plug-together switch connections for straightforward installation
- Low-profile hub minimizes drag and turbulence for smooth water flow
- Includes a 5-blade spline-driven propeller with equal thrust in both directions
What's Included
This is a complete kit. The 140TT 2.0kW thruster unit ships with a fuse, fuse holder, 7m control cable, and locking joystick panel. Only the tunnel needs to be ordered separately.
Parts Desk Insights
Best use case: Ideal for mid-size powerboats and sailboats in the 30–45 ft range requiring reliable bow thrust for single-handed docking or tight-quarters maneuvering. Pair with a compatible Lewmar tunnel (sold separately) sized to the 140TT's tunnel diameter spec. Confirm 12V battery bank capacity before installation — this unit draws significant current at full thrust. Not recommended for vessels already running a heavily loaded 12V system without a dedicated thruster battery.
