Bow Thruster - 185TT 3.0 Kw (4HP) Gen2 - 12v

Lewmar 185TT 3.0kW Gen 2 Bow Thruster — 12V (590006)

A higher-power electric bow thruster unit for larger boats — even thrust in both directions, no maintenance reservoir, and electronics that protect the motor from misuse.

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, undermining the confidence a thruster is supposed to give you. The cassette shaft seal eliminates the need for a top-up reservoir most thrusters require, and Blue Box electronics protect the motor from misuse. The gear set is specifically engineered to handle debris jams rather than just failing when something gets caught. Unlike the smaller 140TT, this size uses a replaceable anode secured with a large nut, easy to swap out in the water without hauling the boat.

Use
Sized for typical boats 33' to 45'. Connects to either a joystick or touch panel controller (sold separately), with plug-together connections and a round back that fits standard instrument panel cutouts. Comes with a 2-meter motor cable and Blue Box ICU included; confirm fuse rating and fuse holder separately for your specific voltage configuration (12V uses a different fuse than the 24V version of this same thruster).
