Imagine gliding into a tight marina slip with confidence, even in crosswinds or strong currents. The Lewmar 185TT 6.0 kW Gen2 tunnel thruster delivers exactly that kind of precision control for mid-sized boats. Designed for sailors and powerboaters who demand reliability without the hassle, this 24V model packs 97 kgf of thrust to make docking a breeze. Unlike older systems that require constant upkeep, the Gen2 series eliminates reservoirs entirely—no leaks, no fluid checks, and zero maintenance headaches.
What sets this thruster apart is its engineering focus on real-world performance. High-performance five-blade propellers ensure balanced thrust in both directions, so you get consistent power whether porting or starboarding. The spline-driven design ditches fragile drive pins, reducing wear and boosting longevity. Paired with a hardened spiral bevel gear, it transmits power quietly and efficiently, keeping noise levels low during those early morning departures.
These aren't just specs on paper; they're proven in demanding conditions from coastal cruising to offshore adventures. Boaters rave about how the Gen2's upgrades deliver smoother, more responsive control compared to first-gen models.
Fitted for a 185 mm tunnel diameter, this 6.0 kW (roughly 8 HP equivalent) powerhouse shines on displacement hulls and planing boats up to around 60 feet, depending on load and conditions. At 24V, it draws efficient power from standard marine battery banks, minimizing voltage drop issues common in 12V setups.

Pro tip: Pair it with a dedicated battery and solenoid for peak performance, ensuring quick bursts of thrust when you need them most.
Installation is straightforward—everything plugs together with a included 2-meter motor cable and the blue-black ICU controller. No need for custom wiring harnesses or hydraulic lines. It's perfect for retrofits on fiberglass hulls or new builds, fitting snugly into 185 mm tunnels without major fiberglass work.
Think beyond docking: Use it for precise station-keeping at anchor, fighting tidal currents, or even windlass assists during anchoring. Saltwater sailors appreciate the sealed design that shrugs off submersion, while freshwater users love the whisper-quiet operation.
Your package arrives ready to install: the full Lewmar 185TT 6.0 kW Gen2 thruster unit, 2-meter motor cable, and blue-black ICU. It's all you need to get maneuvering like a pro.
Electric models like the 185TT Gen2 skip hydraulic reservoirs, eliminating leaks, maintenance, and fluid changes. They're lighter, quieter, and respond faster for precise control.
Absolutely. The stainless steel hub and high-integrity seals provide excellent corrosion resistance, making it ideal for marine environments.
It's optimized for boats 40-60 feet with displacement hulls, delivering 97 kgf thrust for confident handling in winds up to 25 knots.
No routine maintenance needed. Self-resetting thermal protection and sealed components keep it hassle-free—just rinse after use in dirty water.
Choose joystick for tactile feedback or touch panel for sleek helm integration. Both connect easily with plug-together wiring.
Symmetric 5-blade propellers deliver equal 97 kgf thrust both ways, unlike asymmetric designs that lose power in reverse.
Precisely 185 mm inner diameter ensures a perfect fit and optimal water flow for maximum efficiency.
