The owners' manual for my 2001 Mercury 4-stroke (90) does not indicate
how to drain the crankcase oil. How do you do that?


On my 50 Hp Mercury outboards the crankcase oil has to be sucked out the
dipstick tube. The tube has a male hose thread on it so you can easily
attach the hose from a hand pump and suck the oil out.
