Plugs for 2002 225 optimax

[Btuvi]

Searching the forums I find two very definitive statements. One says that NGK IZFR5G gapped at 0.031 is correct.

The other says PZFR5F-11 (no timing mentioned) is correct.

Which one is correct?

Thanks

Just checked and NGK site says PZFR5F-11 gapped at 0.40

Can't find anything on Merc site

Motor serial number is OT581122 if that helps.

I'm beginning to wonder if this is actually a 2002 model.

The -11 plugs mentioned are for 2006 opti.

Come on fellows. I need some input here.

Thanks
