I've always used the Sierra stuff. Ordered from B0ATFIX.COM. Same engines as you.
Part # 47-88032
About 30% less than Merc stuff. I'm on my second tuneup with this boat, and second set of these wires.

I also recommend Sierra marine products. The original Mercruiser wires on my 7.4 arced through after 3 seasons. I replaced them with Sierra wires and they have been running perfectly for the past 7 seasons. I can get any Sierra marine products through my local NAPA auto parts dealer. They cost significantly less than OE Mercruiser parts and IMO they are just as goodif not better.
