Marine engines require ultimate water separation, fuel filtration and maximum fuel flow. Sierra's new filter elements deliver all three of these critical performance factors and are engineered for today’s outboards, sterndrives and inboards.

Sierra has designed these fuel filter cartridges as a direct replacement for the original cartridge elements installed on many Mercury Verado, Optimax and MerCruiser sterndrive engines. Each Sierra filter element is engineered to remove harmful debris while maintaining fuel flow required for these high powered engines.
