Troubleshooting & FAQ
How do I confirm this filter fits my specific engine model and year?
This filter is designed for Mercury 135-200 HP Verado inline 4-cylinder outboards. Please consult the Engine & Model Compatibility table on this page and cross-reference the OEM part number 35-877767K01 with your engine's service manual.
What is the difference between this aftermarket filter and an OEM part?
Our aftermarket filters are engineered to meet or exceed OEM specifications using comparable, high-quality materials. They provide the same performance and protection at a better value, featuring a robust housing and an anti-drain back valve, just like the original.
What is the recommended replacement interval for this oil filter?
Always follow the service interval recommendations provided in your engine’s owner or service manual. Typically, the oil filter should be replaced with every oil change, which is often every 100 hours of operation or annually, whichever comes first.
What are the signs of a failing or clogged oil filter?
Common symptoms include a low oil pressure warning light, a noticeable drop in engine performance, or engine sputtering at high speeds. If you notice these signs, inspect and replace your oil and filter immediately.
Does this filter feature an anti-drain back valve?
Yes, it includes an integrated anti-drain back valve. This feature prevents oil from draining out of the filter and engine galleries when the engine is off, ensuring a quick supply of oil on startup to minimize engine wear.
Is this filter suitable for saltwater use?
Absolutely. The filter is finished with a durable, corrosion-resistant paint to protect the steel housing from harsh saltwater and high-humidity marine environments.
