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 Emission engines.
The Star label will be affixed on the left side of the hull as shown.
