Lewmar 110TT 12v Thruster Kit

The Lewmar 110TT 12v Thruster Kit is engineered for boaters who demand precision boat positioning in tight quarters without constant throttle adjustment. Whether you're docking in a crowded marina, holding position in a cross-current, or maneuvering through narrow channels, this compact bow thruster eliminates the struggle of one-handed helm control. Built by Lewmar—a name trusted across commercial and recreational fleets worldwide—the 110TT delivers the control that separates confident boaters from those fighting their boat.

This 12-volt thruster system operates on a straightforward electro-hydraulic principle: a proportional control lever sends a signal to the thruster unit, which generates lateral thrust independent of engine RPM. The 110TT is sized for smaller to mid-range vessels where a full-sized tunnel thruster would consume excessive space or weight. At 25 pounds, the kit integrates cleanly into modern hull designs without compromising performance or fuel economy. The sealed, stainless-steel construction resists corrosion in saltwater environments, ensuring years of reliable, silent operation during critical maneuvering situations.

Boaters with vessels in the 20–40-foot range benefit most from the 110TT's compact profile and modest power draw. Installation requires a through-hull opening and electrical integration with your vessel's 12-volt system; most marine electricians complete setup in a single day. Compatibility is broad across fiberglass, aluminum, and composite hulls, making retrofit and new-build integration equally straightforward. Once commissioned, the thruster becomes invisible—until you need it, when it transforms a difficult docking into a one-hand maneuver.
