Vetus Stern Thruster Extension for STERN150P

Too little depth, too much air at the propeller – that costs thrust. The Vetus extension kit for the STERN185P lowers both tunnel openings deeper below the waterline, thus ensuring an uninterrupted water flow to the propeller. The result: full thrust from your bow thruster, without the system protruding from under the hull and causing drag.

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