I spotted oil in the valley of lower piece where water pump bolts on to. Oil seal on gear drive dry.1978 Galaxie xl 1700 75 hp Chrysler Outboard.
Drain gear oil in a clean container so you can reuse if new,if old drain it,
You need to find a presure vacumm hand pumptool to test the lower unit gear box for leaks.
Harbor freight tools,amazon,e-bay, google search, buy one.
You tube videos explains it better than i can, it can leak out the drive shaft or prop shaft,

The oil is probably unburned gas/oil.
It leaks down through the cracks and crevices and settles in the low spots.
Change the oil and check for water?
Then do a pressure test if the oil is contaminated.
Some posters parrot their suggestions and really don't have a clue.
