Vetus Stern Thruster Extension for STERN185P

Insufficient depth, too much air at the propeller – that reduces thrust. The Vetus extension kit for the STERN185P lowers both tunnel openings deeper below the waterline, ensuring an uninterrupted water flow to the propeller. The result: full thrust from your bow thruster, without the system protruding obstructively below the hull.

Tip: Before purchasing, check whether your tunnel diameter is actually 185 mm – Vetus also offers the extension kit for diameters of 150 mm, 250 mm, and 300 mm.
