Thruster Replacement Propeller - 185TT

Lewmar Replacement Propeller — 185TT (589351)

A direct OEM replacement 5-blade propeller for the Lewmar 185TT bow thruster — a straightforward, no-adapter swap when the original prop is damaged or worn.

Why It's Worth It
Over time, even the toughest propeller blades develop nicks, bends, or erosion that show up as reduced thrust, vibration, or unusual noise during operation. This is a direct OEM-spec replacement, not a generic substitute, so it bolts on without modification and restores the thruster's original performance — protecting the motor and seals from the extra strain a damaged prop puts on the rest of the system.

Use
A direct replacement for the single 5-blade propeller on the Lewmar 185TT bow thruster. Unlike the 250TT/300TT range, this is not a hand-specific (LH/RH) part — the 185TT runs on a single propeller across the full 110-185 size range, not a counter-rotating pair. Installation is straightforward with basic hand tools.
