Mercury Anode 809662T

Quicksilver – Aluminum Prop Nut Anode | Fits Select Mercury Propellers and Outboard Engines | 2" Diameter | 809662T Overview You can tell a lot about a boater by how they take care of their engine. For those who understand that performance isn’t just about power but also protection, the Quicksilver Aluminum Prop Nut Anode (Part Number 809662T) is one of those small yet vital parts that keeps everything running right. It’s not flashy—but that’s the point. You’ll never notice it working, and that’s exactly why it matters. This anode quietly guards your Mercury outboard or MerCruiser sterndrive from the corrosion that saltwater and electrolysis can bring, extending the life of your propeller, gearcase, and drivetrain. It’s the kind of behind-the-scenes protection that seasoned boaters trust to keep them out on the water, not in the repair shop.

The Quicksilver 809662T Aluminum Prop Nut Anode is your first line of defense against that. Made from high-grade aluminum, it’s designed to take the damage so your more expensive parts don’t have to. Over time, it slowly sacrifices itself to block the electrochemical reactions that cause pitting, rust, and metal loss in your prop and lower unit. The best part? You’ll barely have to think about it. Once installed, the anode works continuously—protecting your propeller, shaft, and gearcase whether your boat is in storage, at dock, or cruising at full speed. It’s a simple bit of insurance that keeps your performance strong, your maintenance costs low, and your peace of mind high. Even if you only replace it once or twice a season, you’ll notice the difference in how your equipment holds up over time—less wear, less corrosion, and smoother, quieter operation.
