Hey Don

[weatherby340]

I have a 2004 225 EFI, model# 1225413cd, SN# OT947272
I know you recommend QL77CC (Champion) for 3 Liter EFI's (.035") however, I was wandering if the NGK 4322 would cause any problems. I'm having a hard time finding the champions. Thanks for your help, I have learned a great deal from your post.

Don, and the Mercury manual specify the Champion QL77CC. And if I recall correctly(may have been someone else)...I believe Don told me he had even seen a PCM that had to be flashed because the wrong plugs erased or corrupted it.

I got the champions online for mine from "sparkplugs.com"....I just looked on there and they are $4.29 each.

Try this new Champion # at any chain parts store.

QL77CC now = 941m

Auto zone, Advance Auto, and Pep Boys all have these plugs for $2.49.

Champion QL77CC only. Doesn't matter "where" you buy them from.... just that you run the appropriate plug!

Thanks for the reply.
I was able to get the QL77CC and does she run much better.
The guy I bought the boat from did not have the right plugs however, we do now.
