Performance & Practical Benefits

The 816296Q03 filter is a small part that makes a big difference in reliability. By removing moisture and fine particles from your fuel supply, it prevents engine hesitation, poor idling, and long-term wear on carburetor components. The clear body lets you keep an eye on fuel flow — if you see dirt or discoloration, it’s time for a swap.

Installation is straightforward: cut the line, slip it in, tighten the clamps, and you’re done. Once in place, it quietly keeps your outboard protected so every start is easy and every throttle push feels clean and strong.

Why Buy OEM

Mercury’s OEM fuel filters are tuned for exact flow rates and filtration levels that match their outboards. Aftermarket filters often use different materials or micron ratings that can restrict fuel flow or let harmful particles pass through.

A genuine Quicksilver filter gives you peace of mind — it fits perfectly, performs reliably, and is tested for the harsh marine environment. It’s one of those inexpensive parts that can save you from major repair costs down the road.
