Troubleshooting & FAQ

How do I confirm this air filter fits my engine?

First, check the "Engine & Model Compatibility" table in this listing. Verify your Mercury outboard's horsepower (75-115 HP) and model series. Second, cross-reference your existing part number with the numbers in our "Part Number Matrix" to ensure it's a direct equivalent.

What are common signs that my air filter needs replacement?

Symptoms of a clogged or failing air filter include reduced engine performance, decreased fuel economy, increased emissions (like black smoke), or difficulty starting. A visual inspection showing heavy dirt or debris is also a clear indicator.

How often should I replace my outboard's air filter?

As a general guideline, we recommend replacing the air filter annually or every 100 hours of operation, whichever comes first. However, if you operate in particularly dusty or salty environments, more frequent changes may be necessary. Always consult your engine's service manual for OEM recommendations.

Is this an OEM or aftermarket part?

This is a high-quality aftermarket replacement part, not an OEM component. It is engineered to meet or exceed original equipment manufacturer (OEM) specifications for fit, form, and function, using comparable materials. It is produced in an ISO 9002 certified facility and undergoes batch inspection for quality assurance.

What are your shipping speeds and costs?

We ship worldwide, and typical transit time is 5–15 days for most regions. Standard shipping is free. If available for your location, expedited shipping options and their costs will be displayed at checkout.

What is the warranty and return policy?

This product is covered by a 1-year warranty against manufacturing defects under normal marine use. If you encounter an issue, please contact our support team with your order number. Returns are accepted within our standard policy window for unused items in their original packaging. Please see our full policy page or contact us for instructions.
