Troubleshooting & FAQ
How do I know if this air filter fits my Mercury Verado?
This filter is made for Mercury Verado 200-300 HP L6 outboards. To ensure a perfect match, please consult the "Compatible Engine Models" table and cross-reference your engine's serial number. The primary OEM part number it replaces is 35-893318T02.
How often should I replace my outboard's air filter?
The standard replacement interval for most Verado models is every 100 hours of operation or annually, whichever comes first. However, if you operate in dusty or debris-heavy environments, more frequent checks are recommended. Always refer to your engine's specific service manual for the most accurate maintenance schedule.
What are the signs of a bad or clogged air filter?
Common symptoms include reduced engine performance, a noticeable drop in fuel efficiency, difficulty starting, or unusual black smoke from the exhaust. A visual inspection will often reveal a filter that is dirty, clogged, or damaged.
