1974 Evinrude 115 hp outboard leaking oil question. With pictures.
Today I looked under the prop and there was a puddle of oil. At 1st I thought it was the final drive lower unit oil. Maybe a bad gasket or a loose bolt from the side. It appeared to be leaking between the prop and the lower unit. 1st I took out the two bolts on the right hand side of the lower unit seen in the pictures below and let it drain. After completely draining I decided to take off the prop. Sure enough I noticed a collection of oil and smelled to be unburned 2 stroke oil. Since the prop is used for the exhaust I felt everything was ok. I know you guys are the experts and would like your input on this with viewing the pictures below.
The boat was last taken out 3 days ago and everything functioned correctly. Power was there and gas is always mixed properly.
2 question I have is this normal for oil to leak?
Also, since I drained the lower unit final drive, how much oil is required upon re-fill?

It is completely normal to get unburnt fuel dribbleing out the exhaust. That motor can live with generic outboard gear lube from Wal Mart. While you are there buy one of those nifty little pumps to put it in.
