Which spark plugs are recommended for the 2007 Mercury 225 Pro XS? Are they the same NGK IZFR6J plugs used in the 250 Pro XS?

Correct! IZFR6J, which should already be gapped at .031-033"

Hi..
I have opti 225, 2007(120h), my Spark Plugs IZFR5G,
Tell, can i replace on IZFR5J ?
Thanks!
If it is the regular Optimax motor and not a Pro XS you need to stick with the IZFR5G. Gap is .032 to .033. Here is some good information to book mark on mercury motor, that Don has put together. Click on the link.
