I'm running NGK's in mine and have all summer. Doesn't seem to load up in the no wake zones like the Champions used to. I'll have to find the number for you. Went with the iridium tipped too, and from what I understand, you really can't foul them out.

Yes!
More eggbeater questions :evilb:

Im not a big Champion fan myself but I havent been able to find a cross reference for this plug. Id be interested to see what Jordy comes back with.

OK, I had to look around to find the receipt (easier than pulling the cover and shrouds off, but I've been running an NGK BR8HIX (iridium) plug all Summer and haven't had a single problem with them. I go them at sparkplugs.com for under $7.00 a piece. Put 60 something hours on the boat without a hiccup. Seemed to run better too from the first time I installed them and motored out of the no wake zone.

QL77PP doesnt show a cross reference anywhere...mine have 80 hours on them and lookie here

Re: merc 300x spark plugs
 

I was running champions too, since switched to NGK. go to www.sparkplugs.com Cross reference to the NGK's.

Re: merc 300x spark plugs
 

Thats where I buy my plugs. They dont list a cross reference and Ive yet to find anyplace or anyone that has an exact match.

What number NGK's are you guys running?

Re: merc 300x spark plugs
 

This is the NGK I am running BZ7HS-10. I did a search on screamandfly last august and this was what they recommended also. I am running 300 promax's, not sure how different that would be to the X's.
