Troubleshooting & FAQ
Why is this decal required in California?
California regulations mandate that outboard motors operated in its waters must display a decal indicating their emission compliance level. The 3-star rating signifies an "ultra-low emission" engine, which is the cleanest category under California Air Resources Board (CARB) standards.
How do I choose the right size for my engine?
Multiple sizes are available to match original OEM decal dimensions for various engine cowlings. It is best to measure the space on your motor where the decal will be placed to select the most appropriate fit from the available options.
Will this decal withstand harsh marine conditions?
Yes, it is made from high-quality vinyl with a protective gloss laminate, making it waterproof, UV-resistant, and resistant to fuel and solvents. It is designed specifically for long-term outdoor durability in marine environments.
What do the different star ratings mean?
The CARB rating system classifies engines based on their emission output levels. The ratings are: 1-star (low emission), 2-star (very low emission), and 3-star (ultra-low emission). A 3-star rating represents the highest level of compliance and the cleanest engine performance.
