Lewmar 140TT Complete Bow Thruster Kit

The Lewmar 140TT thruster kit includes everything needed to install a bow thruster system on boats up to 32 feet. The heart of the kit is Lewmar's 140TT electric thruster, providing 81 lbs of directional thrust at your fingertips for easier docking and maneuvering. Joystick control, control cable harness, fuse and fuse holder all included.

Maneuvering around the dock area can be difficult, but Lewmar's TT Thrusters make docking simple. The revolutionary design of the TT propeller achieves perfectly even thrust in both direction for maximum control and maneuverability. All Lewmar Thrusters have been extensively tested, resulting in smooth, efficient and quiet performance that will have you docking like a pro in no time.

I have the Lewmar 140TT thruster for my 26' center console. Lewmar cannot get the control right. After numerous generations of the controller, they still don't last more than a month or two then becomes problematic and malfunctions. I've gone through 3 or 4 of them already with hopes the new generation would last. NOPE!
