Performance & Practical Benefits

Anyone who has dealt with an exhaust riser gasket knows how much depends on a clean, dependable seal. The exhaust system on an inboard engine doesn’t get the credit it deserves, but it carries intense heat, moisture and pressure — and a bad gasket can cause anything from minor leaks to serious engine damage over time. This Quicksilver gasket is engineered to handle all of it.

You’ll feel the quality the moment you install it. The material compresses evenly, giving you a tight, confident seal that feels secure from the first turn of the wrench. Once everything is bolted back together, you’ll notice steadier engine tone, cleaner exhaust flow and more predictable cooling behavior. It’s the kind of performance upgrade you don’t see from the helm, but you certainly feel in the engine’s reliability.

The gasket is built to resist the constant combination of heat and water that defines marine exhaust systems. Where cheaper aftermarket versions may swell, crack or wear prematurely, this gasket holds its shape and integrity, helping reduce maintenance surprises. It’s a small part, but it supports the kind of dependable engine behavior every boater counts on — whether you’re fishing sunrise flats or taking the family out for a long weekend cruise.

Why Buy OEM

Marine engines are unforgiving places for shortcuts. Aftermarket gaskets might be cheaper, but they often lack the consistency, thickness and heat tolerance needed for high-stress inboard systems. With this Quicksilver OEM gasket, you’re getting a component built to match the exact specs of the engines it replaces, ensuring it seals right the first time. That means fewer do-overs, fewer leaks and more time on the water. If a boater friend asked for real-world advice, you’d probably tell them the same thing: go with the OEM part. It’s a simple choice that pays off in reliability and peace of mind.
