I read in the 1973 Mercruiser manual(orange cover) to use AC CR44TS...I don't believe that is a current number. Looking up the automotive application for the same engine I see AC CR45's...
I also see from some similar posts to stay far, FAR away from Champions, Bosch et al...
Looks like the AC's or NGK's are the most popular.
Any opinions and/or recommendations?
As I said, I have no running issues...just thought I'd replace these at the end of the season.
