Troubleshooting & FAQ

How do I know if this air filter fits my engine?

The best way to confirm fitment is to check your engine's serial number against the ranges listed in the compatibility table. You can also compare your old filter's part number to the ones listed in our Part Number Matrix (Mercury 35-879172143 or VM Motori 41132038F).

What are the signs of a clogged or failing air filter?

Common symptoms include reduced engine power, increased black smoke from the exhaust, higher fuel consumption, and rough idling. A visual inspection may also reveal a filter that is dark, dirty, or clogged with debris.

How often should I replace my marine diesel air filter?

Replacement intervals depend on operating conditions. In dusty or salty environments, more frequent checks are needed. As a general guideline, inspect the filter every 100 hours or annually, and replace it if it appears dirty or damaged.

Can I clean and reuse this foam filter?

This filter is designed as a disposable replacement part. While some foam filters can be cleaned, it is generally recommended to replace it to ensure proper filtration and prevent engine damage from cleaning solvents or filter degradation.

This listing is for an aftermarket replacement, not an original equipment manufacturer (OEM) part. It has been engineered to meet or exceed OEM-level specifications using comparable materials.

How fast is shipping and what does it cost?
