How do you change oil in a 2007 60 hp four stroke mercury bigfoot outboard?

To change the oil in a 2007 60 hp FourStroke Mercury BigFoot outboard, start by warming up the engine briefly to thin the oil, then turn it off. Remove the oil drain plug located at the bottom of the lower unit and allow the old oil to fully drain into a suitable container. Replace the drain plug and use a pump to add new oil through the dipstick tube until it reaches the appropriate level on the dipstick. Finally, run the engine for a few minutes, check for leaks, and recheck the oil level, adding more if necessary.
