What is the proper spark plug gap for the Merc. 240hp efi?

Thanks

0.040" or 1.00mm

I'm glad I saw this thread because the label on my engine says 0.060" (1.0MM)... See attached pic. Is this a misprint or what because when I do the conversion to take 1.0MM to inches it comes back with 0.040"... So the label is giving conflicting information... Which gap is correct?

Humm....



0.060" is = to 1.5mm


Since 1mm is common to both of our info sources... and since I've never really run into a spark plug gap as big as 0.060".... I think they printed your tag wrong.
