1986 Yamaha 90 hp 2 stroke ETLJ Gear oil question

[Blue Man]

Is there a special marine grade gear oil I should use for oiling the gears? Or, can I get something at Auto Zone?

Any specified "marine lower unit oIl" should be fine....in fact I've run The Walmart brand In my 1999 C90 Yamaha for many years without issue.....

Cool. Thanks for the reply!
