If the plugs you have now have worked good, you should be able to cross the old part # over to a new/good #.
I have a 1990 60hp Mercury and wanted to change the plugs. I can not find the ones that are in it because they are old. What plug would do well in this engine? Thanks
Jason

You should be able to find plugs for a 90 model easily.I would stick with NGK if I was you.....
Can`t go wrong with ngk.

I buy mine from West Marine.
Seems to be a location near any wal-mart
If you think there isn't a God, you better be right!
NGK are the only way to go with a mercury motor.
