Overview

There’s a certain peace that comes from maintaining your inboard engine with the right parts — the quiet satisfaction of tightening everything down, knowing the seals are clean, the components are sound and your boat is ready for another honest day on the water. The Mercury Marine part number 8M0162538 Exhaust End Cap Riser Gasket is one of those often-overlooked parts that carries more responsibility than its size suggests. When you replace a riser gasket with a proper OEM-quality component, you restore the confidence that your cooling system and exhaust flow are working exactly as they should. It’s a small change that pays off every time you crank the engine and hear it settle into that familiar, steady rhythm.

Performance & Practical Benefits

Exhaust riser gaskets do a lot of heavy lifting. They help keep exhaust gases contained, ensure proper water flow through the cooling system and protect the engine from leaks that can turn into expensive repairs. When a gasket starts to fail, the symptoms show up slowly — a faint exhaust smell, uneven cooling, moisture where it shouldn’t be. Replacing it with a Quicksilver gasket ensures your system goes back to feeling tight, smooth and secure.

The moment you install this gasket, you’ll feel how well it seats. The material compresses exactly the way a marine gasket should, creating a uniform seal that stands up to vibration, pressure and the cycle of heating and cooling your exhaust system goes through every trip. Once installed, your engine runs steadier. Cooling passages flow the way they should, and exhaust leaves the system cleanly without restriction or backflow.

Unlike cheap aftermarket versions, this gasket is engineered for long-term reliability. It won’t swell, crack or crumble prematurely. It resists moisture, salt and heat — all the things that punish marine components year after year. It’s the kind of part you install once and don’t think about again for a long time, which is exactly how a good gasket should behave.

Why Buy OEM

When it comes to exhaust and cooling systems, shortcuts are never worth it. OEM gaskets are made to fit exactly, seal exactly and last exactly as long as the manufacturer intended. Aftermarket versions might be cheaper upfront, but inconsistencies in thickness or material quality can lead to misalignment, leaks and early failure. Quicksilver parts are built to meet Mercury’s demanding standards, ensuring you get the durability and peace of mind that only true OEM components provide. Ask any seasoned boater — exhaust parts are not the place to gamble.
