Lewmar Thrusters

When precision maneuvering matters most, Lewmar delivers thruster technology engineered for exceptional control. The company's TT Thruster series represents decades of marine engineering expertise focused on solving one of boating's most challenging tasks: confident docking in tight quarters, strong currents, and adverse conditions.

Revolutionary TT Propeller Design

The revolutionary design of the TT propeller achieves perfectly even thrust in both directions for maximum control and manoeuvrability, setting Lewmar apart in the thruster category. This balanced thrust delivery means you get consistent performance whether pushing port or starboard, eliminating the asymmetric power characteristics that plague conventional thruster designs. High performance 5 blade propellers give equal thrust in both directions, providing the predictable response experienced captains demand during critical docking maneuvers.

Comprehensive Product Range

Lewmar's electric thruster lineup spans from compact 140TT models for smaller vessels to powerful 300TT units for boats approaching 21 meters in length. The electric range of thrusters are available in power outputs ranging from 28Kgf (1.5kW) to 250Kgf (10.8kW) in both 12 and 24 volt models with tunnel sizes ranging from 110mm to 300mm. This extensive selection ensures proper matching to your vessel's displacement, windage characteristics, and operational requirements.

GEN 2 Blue Box Technology

The GEN 2 blue box system is their next-generation thruster system with main electronic components completely redesigned to increase reliability and functionality. This intelligent control system provides motor protection from overheating, incorporates direction change delays to prevent internal damage, and integrates seamlessly with both joystick and touch panel controllers. The blue box architecture represents Lewmar's commitment to long-term reliability in harsh marine environments.

Proven Performance Advantages

All Lewmar Thrusters have been extensively tested, resulting in a smooth, efficient and quiet performance that enhances the onboard experience. The hardened spiral bevel gear system delivers maximum power transmission efficiency while minimizing operational noise—critical when maneuvering in crowded marinas. Lewmar thrusters are suitable for all kinds of boats, from monohulls to pontoons to houseboats, demonstrating the versatility of their tunnel thruster platform across diverse hull configurations.

With no hydraulic reservoir to install or maintain, self-resetting thermal protection on all motors, and high-integrity seals engineered for saltwater durability, Lewmar thrusters combine performance with practical serviceability that marine operators appreciate over years of use.
