Correct ignition wires

[JGJR]

It is time to replace the coil and plug wires on my Mercruiser 4.3l tks. The local dealer I usually buy from is currently closed so I bought a set from Amazon. They arrived today, and I notice the part number doesn't match what is listed in the manual, and the wires are black instead of blue. The part number in the manual is
84-863656A04
and the part number of the set I received is
84-816761Q16

My fault, these are the ones I ordered, they're Mercruiser and labeled on the box "Fits GM V-6 CID engines with Thunderbolt IV ignition (1985 and newer)", which is the engine i have. Why the difference, and are these ok to use?

Actually, these are Quicksilver brand, which, I believe, is made by Mercury, if that matters. Forgot to mention in my original post.

I would return them and use the recommended blue wires. They provide max voltage,Protects electronics/rfi/emi when compared to standard hypalon. I couldn't even link the two kits by cross reference.

Ayuh,..... Quicksilver is just Merc's aftermarket brand,...... No problem,.....

I'm having difficulty finding the correct kit with matching serial number. Does anyone happen to know of a source? I'm striking out on Amazon, and the one source I found on Google with the correct serial number had a picture showing the exact same kit, black wires, that I have now. Any help is appreciated.
