does anyone know the right spark plug for a 2005 regular optimax 225hp? a friend mine has a boat at the lake and we want to get spark plugs for it before we go down, it's an OB1 serial number and the only one I can find is for the pro in the catalogues.

I changed out literally over 1000 dollars worth of these babies during my internship with mercury. If my memory serves me right, they are NGK Platinums IZFR5G. The stock number is #5887 for NGK's.
