Owner Responsibility

The operator must have routine engine maintenance performed to maintain emission levels
within prescribed certification standards.
The operator may not modify the engine in any manner that alters the horsepower or allows
emissions levels to exceed their factory specifications.

Emission Certification Star Label

Your boat is labeled on the hull with one of the following star labels. The Symbol for Cleaner
Marine Engines Means:
1. Cleaner Air and Water ‑ for a healthier lifestyle and environment.
2. Better Fuel Economy ‑ burns up to 30‑40 percent less gas and oil than conventional
carbureted two‑stroke engines, saving money and resources.
3. Longer Emission Warranty ‑ Protects consumer for worry free operation.
Beginning January 1, 2003, one Three‑Star or Four‑Star label will be included with each
factory‑certified Mercury MerCruiser engine.
All Mercury MerCruiser engines (500 hp and below) will have a Three‑Star Ultra Low
Emission rating or Four‑Star Super Ultra Low Emission rating. The Star label identifies that
these engines meet the California Air Resources Board's Sterndrive and Inboard marine
engine 2007 and later exhaust emission standards. Engines meeting these standards have
65‑90% lower emissions than One‑Star – Low Emissions engines.
The Star label will be affixed on the left side of the hull as shown.
