Well guys this is new to me,<br /> I know how to tune an engine, but this boating and stern drive stuff is new to me. I live up in Canada in the boonies and well I tried to get a manual but they are all on back order :( Any way I have a 1991 four winns 23' 225 sundowner. It has a OMC 5.8 L cobra engine with omc drive. This is simple I want to know how to change the gear oil or at least check to see if I have to add any. <br /> My second question is can I add Slick 50 to the 5.8 L engine. <br /><br />Thanks for any responses<br />Scooby

The center screw is a dipstick. Check level with the drive trimmed level.
