Replacement of Certification Label
IMPORTANT: By federal law, it is required that all 1998 and newer Mercury Marine
outboards have a visible and legible emission certification label. If this label is mis-
sing or damaged, replacement labels can be obtained from Mercury Marine.
Removal
Remove all remaining pieces of the damaged or illegible label. Do not install new label
over the old label. Use a suitable solvent to remove any traces of the old label adhesive
from the display location.
Date Code Identification
Cut and remove a “V” notch through the month of engine manufacture before installing
the new label. The month of manufacture can be found on the old label. If the label is mis-
sing or the date code illegible, contact Mercury Marine Technical Service for assistance.
