Mercury and Mariner use different oil filters depending on engine model, year, displacement and serial number.
Not every Mercury / Mariner 8–30 HP outboard uses this filter.
If the part looks the same as yours, it is not always the correct one for your outboard.
Please confirm your engine model, serial number and original oil-filter part number before purchasing.
