I got a merc 50 and it came with autolite plugs (p#unknown) when I bought it. When I changed them last year I could not find autolites so I converted over to NGk (BUHW-2)and ran them ever since. It doesn't seem my engine runs as good when I first got it. It kinda seems a little slower. When I looked in my owners manual it recommeds AC-V40FFK or champion L78V. should I run AC Delco or Champions over Ngk. I always thought NGK was the mercury plug of choice. I'm kinda confused if someone one could shine some light on this it would really help me.
