Mercury – Quicksilver Engine Gasket | 4-Stroke 8–9.9HP Outboards | 802699002
Overview
A good gasket might not look like much, but it’s one of the unsung heroes inside your outboard. The Mercury Marine 802699002 Quicksilver Engine Gasket keeps your Mercury 8–9.9HP FourStroke carbureted (209cc) engine sealed tight so it runs smooth and clean. Built from heat-resistant, fuel-safe materials, this OEM gasket handles the constant pressure and vibration of marine use without shrinking or breaking down. It’s an exact-fit replacement that helps prevent leaks, maintain compression, and keep your outboard performing the way it should.

Performance & Real-World Benefits
The 802699002 gasket does more than just seal — it preserves your engine’s power and reliability. When an old gasket wears out, tiny leaks can reduce compression or let oil seep into places it doesn’t belong. Replacing it restores the tight seal your motor needs for smooth operation and full efficiency.
It’s a quick and inexpensive repair that prevents bigger issues later. Whether you’re rebuilding the engine or doing routine maintenance, using a proper OEM gasket keeps your Mercury running strong and clean season after season.
Why Choose Mercury OEM
The Quicksilver 802699002 is a genuine Mercury Marine part, cut to fit your engine exactly. Cheaper aftermarket gaskets often use weaker materials that fail under marine heat or don’t align perfectly, which can lead to leaks or loss of compression.
Mercury OEM gaskets are tested for durability, heat resistance, and long-term sealing in marine conditions. Choosing OEM means you’re using the same high-quality materials Mercury installs at the factory — reliable, proven, and built to last.
