Performance & Practical Benefits

This kit is all about keeping your engine protected where it matters most.

Everything fits perfectly because every part is built to Mercury’s specs, ensuring tight threads, proper dimensions, and a clean, straightforward installation.

Why Buy OEM

OEM Mercury parts deliver consistency that aftermarket alternatives just cannot match. The filtration media, housing strength, internal design, and corrosion resistance are all engineered specifically for Mercury engines. That means better protection, longer service intervals, and fewer unexpected problems.

Buying genuine Mercury parts is an investment in longevity — and in the peace of mind that your engine is protected by the same components Mercury relies on at the factory. It is practical, cost-effective, and the best way to keep your sterndrive or inboard running at peak performance.
