Mercury – Quicksilver 8M2004414 Exhaust Elbow Gasket | Standard Cooling Series | Marine Composite | 8M2004414

Overview

Anyone who’s spent enough weekends on the water knows that a dependable engine isn’t just about horsepower—it’s about the small, unseen parts quietly doing their job trip after trip. The Quicksilver 8M2004414 Exhaust Elbow Gasket is one of those parts. It sits tucked away in your V6 or V8 MerCruiser, creating a tight seal that keeps water and exhaust exactly where they’re supposed to be. And when it’s doing its job right, you feel it in the smoothness of your ride, the steadiness of your idle, and the peace of mind that settles in when you’re miles from the dock with nothing but open water ahead.

Performance & Practical Benefits

A failing exhaust gasket can make itself known in all the worst ways—moisture where it shouldn’t be, exhaust leaks, sluggish performance, or that uneasy feeling when the engine sounds just slightly “off.” Installing a fresh Mercury Marine part like the 8M2004414 gasket brings everything back to the tight, smooth, predictable operation you expect.

Once in place, the gasket forms a clean, even seal that holds up against long hours of engine heat and cold water pass-through. You’ll feel the difference in how steady the engine runs, especially when idling or loading up passengers. Because Quicksilver builds it to Mercury’s exact specs, the fit is precise, the edges match perfectly, and there’s no wrestling or trimming during installation. It’s the kind of part that simply goes in, does its job, and lets you get back to running your boat instead of fussing with repairs.

In real-world use, this gasket helps protect expensive components from premature wear, keeps exhaust passages flowing properly, and supports the overall health of your cooling system. It’s a small investment that pays you back every time you turn the key.

Why Buy OEM

With exhaust components, shortcuts can cost you—sometimes literally. Aftermarket gaskets may look similar but often lack the material density, heat tolerance, or exact shape needed for a perfect seal. Mercury’s OEM version is engineered specifically for these engines, tested under marine-specific conditions, and designed to last. Choosing OEM means fewer surprises, fewer repeat repairs, and the confidence that you’re protecting the core of your boat’s power system. For a part this critical, OEM is the smart, seasoned boater’s choice.
