Made from durable, marine-tested composite material, it keeps exhaust gases sealed and prevents leaks that can rob power or damage nearby components. Key Features Purpose: Seals the exhaust manifold to prevent gas leaks and maintain proper backpressure. Material: Constructed from marine-grade composite that withstands heat, pressure, and vibration. Performance: Maintains a leak-free seal, protecting your engine and improving exhaust flow. Durability: Resists warping, cracking, and corrosion even in harsh marine environments. Compatibility: Designed for V8 GM-based engines (454, 482, 496, 502, and 540 CID) used in MerCruiser, OMC, and Volvo Penta sterndrives and inboards. Fitment: Built to Mercury OEM specifications for perfect alignment and easy installation. Engine & Boat Compatibility V8 MerCruiser sterndrive and inboard engines (454, 482, 496, 502, and 540 CID) OMC sterndrives and inboards using similar CID GM-based engines Volvo Penta sterndrives and inboards with compatible GM V8 blocks Commonly found on offshore boats, cruisers, and high-performance inboards Performance & Real-World Benefits The 46820 exhaust gasket ensures a clean, tight seal between the manifold and cylinder head, preventing hot gases from escaping and keeping exhaust flow efficient. A proper seal helps your engine maintain backpressure, reduces noise, and protects against corrosive gas leaks that can damage the manifold or block. Made to handle the extreme temperatures and vibration of marine engines, this gasket stays intact where ordinary automotive gaskets fail. Whether you’re cruising or running at wide open throttle, it keeps your exhaust system sealed and performing the way it should. Why Choose Mercury OEM The Quicksilver 46820 is a genuine Mercury Marine gasket , engineered specifically for marine-grade performance. Generic gaskets often use weaker materials that break down under heat or salt exposure. Mercury’s OEM gaskets are precision-cut, pressure-tested, and proven to hold up to years of use in demanding conditions. Installing OEM ensures the perfect fit and seal, protecting your investment and keeping your engine running strong. FAQ Q1: Which engines does this gasket fit? It fits V8 MerCruiser sterndrives and inboards (454, 482, 496, 502, and 540 CID) and compatible GM-based engines from OMC and Volvo Penta . Q2: What’s it made from? A marine-grade composite engineered to resist heat, pressure, and corrosion. Q3: When should I replace the exhaust gasket? Replace it any time you remove the manifold or notice exhaust noise, leaks, or discoloration around the joint. Q4: Can it handle saltwater environments? Yes — it’s made for long-term durability in both saltwater and freshwater conditions. Q5: Why use Mercury OEM instead of an aftermarket gasket? OEM gaskets ensure exact fit, even sealing, and materials that won’t degrade under marine heat and pressure.
