Service Replacement Certification Label
IMPORTANT: By federal law, it is required that all 1998 and newer Mercury Marine out-
boards have a visible and legible emission certification label. If this label is missing
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 missing
or the date code illegible, contact Mercury Marine Technical Service for assistance.
