Lewmar 185TT 6.0Kw 8HP Gen2 12v Bow Thruster

The Lewmar 185TT 6.0Kw 8HP Gen2 12v Bow Thruster is a marine propulsion unit engineered for vessel positioning and lateral maneuvering in confined waters. Designed for tactical marine operations and professional vessel control, this bow thruster delivers independent thrust authority without reliance on main engine controls. The unit serves law enforcement, coast guard, and military maritime platforms requiring precise low-speed positioning in harbors, alongside docking procedures, and high-pressure operational environments where traditional steering alone proves insufficient.

This Gen2 thruster generates 6.0 kilowatts (8 horsepower) from a 12-volt electrical system, driving a high-performance 5-blade propeller that produces equal thrust in both forward and reverse directions for symmetrical maneuvering capability. The tunnel-mounted design eliminates the need for external reservoirs, reducing installation complexity, eliminating hydraulic fluid leakage hazards, and removing routine maintenance requirements—critical factors in austere maritime environments. A high-integrity seal system protects internal components from saltwater corrosion and debris ingestion, while the spline-driven propeller eliminates mechanical drive pins that can fail under stress, improving reliability during mission-critical operations.

Maritime professionals operating rigid-hull inflatable boats (RHIBs), patrol craft, and tactical watercraft benefit from the Lewmar 185TT's responsive lateral control during search and rescue, interdiction, and security operations. Installation requires integration with existing 12-volt vessel electrical systems and a bow tunnel aperture sized for the 185-millimeter thruster housing. At 40 pounds, the unit's compact weight signature minimizes topside load distribution while delivering sufficient thrust for vessel beam positioning and precision anchorpoint holding in current-affected waters. This thruster is ideal for operators demanding redundant maneuvering capability and zero-maintenance propulsion in high-utilization maritime platforms.
