Quicksilver water-separating fuel filter 35-8M0093688 is an original filter element for the Gen III Cool Fuel module on compatible MerCruiser gasoline engines. The filter removes water and fuel-borne impurities in the fuel cooling chamber before they are passed further through the engine's fuel system.
The filter has a proven filtration efficiency of 95% at 15 microns. The filter medium consists of polyester, cellulose, and fiberglass with a phenolic binder and silicone coating. One filter element and two rubber gaskets are included for the replacement.
The part is documented for MCM and MIE engines with a Gen III fuel cooler, including select 5.0L MPI, 350 MAG MPI, 496 MAG, MX 6.2L MPI, 8.1L, and 8.2L MAG variants. The Quicksilver accessories guide specifies use for MCM/MIE engines from 2004–2015, while other current sources also specify later engines. Therefore, always check the engine serial number and parts catalog before ordering.
Part number 35-8M0093688 replaces the previous numbers 866171A01 and 35-866171A01. Compare the existing filter and part number to ensure the correct variant for the engine's Gen III Cool Fuel system is selected.
