Performance & Practical Benefits

The skeg does more than protect your lower unit — it stabilizes your boat. When it’s bent or broken, you’ll feel it immediately in steering response and tracking. The 15985A02 Replacement Skeg restores that factory feel, helping your boat run true at idle or wide-open throttle.

Its cast aluminum construction is strong yet hydrodynamically smooth, so it won’t create drag or turbulence. Once installed, it fits flush and clean with your gearcase, keeping water flow efficient and control predictable. It’s a simple part that plays a major role in how your boat handles and performs.

Why Buy OEM

Aftermarket skegs often look similar but rarely fit as precisely as Mercury’s. Even a small difference in shape or angle can throw off your handling or prop efficiency. The Quicksilver 15985A02 is a genuine Mercury Marine part, cast and machined to the same specs as your original gearcase.

With OEM quality, you get the exact balance, strength, and finish that your engine was designed around. It bolts on cleanly, lines up perfectly, and lasts longer — no reshaping, no guesswork, just factory-correct performance and protection.
