Bow Thruster - 185TT 4.0 Kw (5.4HP) Gen2 - 12v

Lewmar 185TT 4.0kW Gen 2 Bow Thruster — 12V (590008LEW)

A mid-power electric bow thruster for mid-to-larger boats — even thrust in both directions, no maintenance reservoir, with a replaceable anode for easy in-water servicing.

Why It's Worth It
The 5-blade composite propeller delivers genuinely equal thrust whether you're pushing the bow left or right, which matters far more than it sounds — uneven thrust makes a boat handle differently depending on direction. The cassette shaft seal eliminates the need for a top-up reservoir most thrusters require, and Black box electronics protect the motor from misuse. Hardened, ground spiral bevel gears keep power transmission quiet and efficient, and plug-together switch connections make installation and maintenance straightforward.

Use
Intended for use in 185mm thruster tubes. Comes with the thruster unit, a 2-meter motor cable, and Blue Box ICU included; a complete system still requires a control panel, control cable, fuse holder, and fuse, plus the thruster tunnel, sold separately. Connects to either a joystick or touch panel controller. Note: the 185TT 4.0kW size is available in both 12V (590008LEW) and 24V (590009LEW) versions — confirm voltage before ordering.
