Troubleshooting & FAQ
How do I know if this oil filter fits my engine?
This filter is designed for Mercury/Quicksilver 75-115 HP FourStroke (1731cc) engines with serial numbers from 1B366823 to 2B094995, and the 150 HP EFI FourStroke model. Always verify your engine's part number or serial range against our compatibility table.
What is the recommended replacement interval?
For optimal engine protection, we recommend replacing the oil filter with every oil change, or at least once per season, following your engine manufacturer's service schedule.
