Re: o2 sensor location 250hp ox66
Its Located On Rear Starboard Side Of The Motor On Top , Its A Black Box Mabey 3x6 Inches With A Cylindrical Top Through Which The Sensor Wires Pass, Remove The Cover 3 Screws, Slide The Cover Up The Cable Remove The Metal Sensor , Three More Screws, You Will Find A Small Barbell So To Speak That Slides In And Out ,clean This And The Housing I Use A Half Inch Plumbers Wire Brush, There May Be Tough Carbon Build Up, You Can Un Screw The Sensor From The Metal Part To Clean Also. You May Need New Gaskets
