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
