Changing the gear oil in a 4 stroke outboard, is the same proceedure as with the 2 stroke.
Remove the drain plug, at bottom of gearcase, remove vent plug at top of gearcase and let drain. Fill from bottom, (drain plug hole), until lube runs out of top, (vent plug hole). While blocking off drain plug hole, to keep oil from draining, replace vent plug. Make sure that plug gaskets are in place and in serviceable condition. Quickly, replace the drain plug.

How do you change oil on a mercury 60 hp four-stroke outboard?
I just changed the oil in my mercury 60 hp 4 stroke and had very little clean up. I let the oil completely drain from the motor before I removed the filter and had No drips there either. Just over 30 minutes to change motor oil and lower unit oil. Total cost of $35.00 included quicksilver 25W40 quicksilver oil filter and quicksilver 80/90 gear oil. Take your time and save your money . No reason to pay a dealer $150 to $250. for this simple oil change. Charliestoybox
