Hi men, I have a 1988 Mercruiser, 260 hp, 350 CID. What plugs run best in these engines and what number are they? Thank you, Bob

Spark Plugs

I just looked your engine up and it says that you should run AC MR43T spark plugs gapped at .035. The Mercury part # is 33-898264001. If you need help getting these let me know.

Thanks!
