Important – Check Compatibility
Mercury uses different oil filters across its FourStroke engine generations.
This filter is not suitable for all 75–115 HP FourStroke engines, particularly later 2.1L models.
It should also not be confused with the oil filters used on Mercury Verado L4 or L6 engines.
Please check your complete engine model, serial number and original oil filter reference before ordering.
If the filter looks the same as yours, it is not always the correct one for your outboard.
OEM part numbers are used for compatibility reference only.
