This replacement water separating fuel filter can be used on all Mercury Marine outboards (Mercury, Mariner or Force) and all MerCruiser sterndrive and inboard engines except 1992 MerCruiser 4.3L Gen II engines equipped with an inline fuel filter and not on 1.6L Vazer and 3.0L MPI engines. Don’t let water moisture or other fuel contaminants rob horsepower from your engine. Filter those particles before they can get to your engine. Includes replacement filter and rubber gaskets for installation.
