I did an oil change at the end of last season and bought merc oil with the part #92-858053K01 (see attached photo). I bought this from a local boat shop and while it says OUTBOARD engine oil, the owner stated this is also for stern drive engines. After doing a little research it looks like this oil has been superseded by part #92-8M0078630. No worries there, I just wanted to make what I bought is appropriate for this engine.
