Engine Data Label
A tamper‑resistant engine data label is affixed to the engine at the time of manufacture. It contains important information. Note
that the engine data label will not affect the fit, function, or performance of the engine and neither boatbuilders nor dealers may
remove the engine data label or the engine component it is affixed to before sale. If modifications are necessary or the engine
data label is damaged, contact Mercury Marine about the availability of a replacement.
The owner or operator is not to modify the engine in any manner that would alter the horsepower or allow exhaust gas emission
levels to exceed their predetermined factory specifications.
