Went to replace spark plugs in my 1976 mercruiser 888... And apparently I ordered the wrong plugs:
The plugs I read were right are NGK A6FS. What came out is a much smaller motorcraft ARF52.
The previous owner's mechanic (my best friend's dad) is a retired Ford tech... So finding car parts is not a surprise. But, the obvious mechanical incompatiblity is a head scratcher.
I don't know if the heads are stock (I've asked; the intake and above are not stock at least).
Serial number:
What plugs should I get?
