Performance & Practical Benefits

The 816296Q2 filter keeps your fuel clean so your engine can breathe and perform the way it should. Even a tiny bit of debris or water can cause hesitation or poor idling — this filter catches it before it ever reaches the carburetor or fuel injectors.

The transparent housing lets you keep an eye on what’s flowing through your line. When you spot dirt or discoloration, you’ll know it’s time to replace it. Installation takes just a few minutes, and you’ll be back on the water with peace of mind that your fuel system is protected.

Why Buy OEM

Mercury’s OEM fuel filters are designed and tested for their engines’ exact flow and pressure needs. Aftermarket filters might look the same, but internal differences in micron rating or materials can restrict fuel flow or break down faster in ethanol-blended fuels.

With genuine Quicksilver parts, you get the proper flow, the right fit, and long-lasting protection — all engineered for marine conditions. It’s a simple way to protect your engine’s performance and longevity.
