Lewmar 185TT6.0 Kw 8HP Gen2 24v Bow Thruster

The Lewmar 185TT6.0 Kw 8HP Gen2 24v Bow Thruster is a precision marine propulsion system engineered for vessels requiring independent directional thrust independent of main engine operation. Designed for law enforcement patrol boats, military fast-response craft, and professional maritime operators, this bow thruster delivers silent maneuvering capability in confined waterways, harbor approaches, and tactical insertion scenarios where engine noise discipline is critical. The 24-volt electrical architecture integrates seamlessly with modern patrol vessel electrical systems, providing redundant positioning authority when vessel-control margins are narrow.

The Lewmar 185TT6.0 Kw 8HP Gen2 24v Bow Thruster produces 8 horsepower of lateral thrust through a brushless tunnel-mount motor rated at 6.0 kilowatts, utilizing advanced impeller geometry to minimize cavitation and maximize thrust coefficient in both freshwater and saltwater operating environments. Generation 2 internals feature sealed bearing assemblies and corrosion-resistant materials compatible with marine duty cycles extending 5,000+ operating hours. The 24-volt DC motor architecture enables direct integration with marine auxiliary battery banks, reducing installation complexity and eliminating the need for dedicated DC-to-AC conversion systems found in competing designs.

Professional operators—including Coast Guard auxiliary units, port security teams, and commercial offshore support vessels—rely on the Lewmar 185TT6.0 for precision station-keeping, docking operations under adverse current, and dynamic positioning when main propulsion is offline. Installation requires tunnel mounting through the bow structure and integration with 24-volt control systems; consult vessel electrical schematics and Lewmar installation documentation to confirm compatibility with your specific hull type and electrical architecture. At 50 lbs, the motor assembly requires proper structural reinforcement at mounting points to ensure load distribution across adequate hull material.
