Got a new to me boat with a 2004 Optimax 250xs, serial# 0T818269. I'm going to change spark plugs and called mercury for what plug I need and they told me NGK IZFR6J but the sticker on the motor says I need NGK PZFR6H. I see in the sticky section of here Don says 225-250 racing xs motors take the NGK IZFR6J as well but the sticker on the motor is causing me to hesitate. Any input would be nice.
Thanks
I would go by the sticky section here.

IZFR6J is it your engine does not use the P= platinum plugs updated to I=iridium with new number
