Vetus SDKIT150 Stern Thruster Extension Kit for Shallow Draft Boats Ø150 mm
The Vetus SDKIT150 extension kit is engineered to ensure reliable stern thruster operation when the tunnel openings are installed close to the waterline. On shallow draft boats or vessels with transom-mounted systems such as trim tabs, outdrives or platform brackets, a standard stern tunnel may allow air to be sucked into the thruster. This kit extends the tunnel opening below the water surface, preventing thrust loss and ensuring consistent maneuverability. The set includes two GRP shells and corrosion-resistant stainless steel fastenings for secure installation and long-term durability.
