It suits thrusters with a 513 mm tunnel diameter (BTH 513 and BTAC 513).\u003c\/p\u003e\u003cp\u003eQuick recommends that preparation and positioning of the tunnel in the hull is entrusted to a skilled professional, and the installer bears responsibility for any problems caused by defective installation. The tunnel should sit as deep as possible, at least 0.75 times the tunnel diameter from the waterline, to avoid propeller cavitation (Quick thruster manuals). Check the thruster manual for tunnel length and tube thickness limits for your model.\u003c\/p\u003e","brand":"Quick","offers":[{"title":"Default Title","offer_id":57450629398868,"sku":"FGTLA5132222A00","price":7571.75,"currency_code":"GBP","in_stock":true}],"url":"https:\/\/hudsonmarine.co.uk\/products\/quick-bow-thruster-tunnel-513mm-x-2200mm-steel-e-355-22mm-wall","provider":"Hudson Marine Electronics","version":"1.0","type":"link"}
