Lewmar 185TT Gen 2 — 12V Bow Thruster, 3.0kW
The entry point into the Lewmar 185TT Gen 2 platform, the 3.0kW model delivers dependable bow thrust for mid-size vessels where precise docking control is a priority. It shares the same sealed, low-maintenance architecture as the higher-output 185TT variants — just scaled to a lower power draw that suits a wider range of 12V electrical systems.
Key Features
- Sealed, reservoir-free design — no hydraulic fluid, no leaks, no routine maintenance
- High-integrity motor seal for long-term reliability in saltwater and freshwater environments
- Black box electronics module protects the motor from overload and voltage irregularities
- Hardened spiral bevel gears for efficient, quiet power transfer
- Self-resetting thermal protection on all motors — no manual reset required after overload
- Plug-together switch connections for straightforward installation wiring
- Low-profile hub minimizes drag and turbulence at speed
- 5-blade spline-driven propeller delivers equal thrust in both directions
What’s Included
This listing is for the 185TT Gen 2 3.0kW thruster unit only. A complete installation also requires a control panel, control cable, fuse holder, fuse, and tunnel — all available separately. Contact us to help spec a complete system.
Parts Desk Insights
Best use case: Best suited for powerboats and sailboats in the 35–45 ft range where the 185TT tunnel diameter is the right fit but a lower-output unit is preferred. The 3.0kW rating is the most accessible of the 185TT Gen 2 range in terms of electrical demand, making it a practical option for vessels without a dedicated high-capacity thruster battery. Ideal for owners upgrading from a smaller thruster platform who want the 185TT tunnel size without committing to the higher current draw of the 4.0–6.0kW variants. Tunnel, cabling, and control panel are separate line items — confirm tunnel diameter compatibility before ordering.
