FUNCTIONAL APPLICATION — DIESEL ENGINE OIL FILTRATION:
Per Mercury Marine and Quicksilver documentation, this oil filter is specifically designed for MerCruiser 7.3L diesel engine applications. The filter removes pollutants from the engine lubricating oil including dirt, soot (characteristic of diesel engines), and metal particles — essential for long engine life in marine diesel applications. Following the manufacturer's recommended filter replacement schedule is critical for diesel engine longevity, as diesel engines produce more soot than gasoline engines and require more frequent oil filter changes.

FITMENT NOTE:
This is an OEM-spec replacement Oil Filter for MerCruiser 35-805809T (and 35-805809). ALWAYS verify the OEM part number from your MerCruiser service manual or owner's manual before ordering. This filter is for DIESEL applications — NOT for gasoline V6/V8 MerCruiser engines (which use different OEM numbers like 35-866340K01). Confirm your application is the 7.3L diesel before ordering.
