Troubleshooting & FAQ
How do I confirm this filter fits my specific engine?
Compare the original filter with the verified reference 35-879884T, then match your engine's model, cylinder configuration, stroke, and complete serial-number range against the compatibility table. If any detail differs, consult the engine service manual or a qualified marine technician before ordering.
Is this an OEM Mercury part?
No. This is an aftermarket replacement listed for the Mercury reference shown above. Mercury and Mariner are trademarks of their respective owner and are used only to identify application compatibility.
Does the part fit every Mercury or Mariner 30–60 HP 4-stroke engine?
No. The 30–60 HP range is not sufficient by itself to confirm fitment. Serial-number ranges and engine configuration must match the applicable catalog listing. The verified catalog evidence available for this product covers the Mercury applications shown on this page; verify any Mariner application separately.
What are common signs that a fuel filter may need replacement?
Possible symptoms include hard starting, hesitation, loss of power, or stalling under load. These symptoms can have several causes, so inspect the fuel system and follow the engine manufacturer's diagnostic procedures.
How often should the filter be replaced?
Replacement intervals vary by engine model, fuel quality, operating conditions, and the manufacturer's maintenance schedule. Follow the service interval in your engine manual and replace the filter sooner if contamination or restriction is found.
What are the shipping options?
We ship worldwide quickly—typical transit is 5–15 days. Standard shipping is free; expedited options appear at checkout where available.
What is the warranty and return policy?
This part is covered by a 1-year warranty against manufacturing defects under normal use. Returns are accepted within the standard return window when the part is unused and in its original condition. Contact support with your order details for assistance.
Safety & Important Info
- Verify the part number, physical configuration, engine model, and complete serial number before purchase.
- Fuel is flammable. Work in a well-ventilated area away from ignition sources and dispose of spilled fuel properly.
- This is an aftermarket replacement, not an OEM component.
- Professional installation is recommended for safety and performance.
