Mercury – Aluminum Anode Kit | Corrosion-Defense Series | Cast Aluminum | 8M6007985

Overview

If you spend enough time on the water, you learn quickly which parts quietly protect everything else. Anodes fall into that category—small pieces of metal that stand between your engine and the slow, grinding damage that saltwater can deliver. The Quicksilver 8M6007985 Aluminum Anode Kit is one of those parts that gives you peace of mind. When you know your Yamaha outboard is shielded from galvanic corrosion, you can focus on the ride, not the worry.

There’s something reassuring about installing a fresh anode kit at the start of the season. It’s a simple job, but it pays off every single time you drop the lower unit into the water.

Performance & Practical Benefits

Galvanic corrosion works quietly, and it works constantly. Aluminum anodes fight that process by sacrificing themselves before your underwater components start to wear. This kit ensures your Yamaha’s lower unit, mounting brackets, and other exposed metals stay protected season after season.

You’ll notice the difference in the long run—cleaner metal surfaces, less pitting, and far fewer surprises at haul-out. The cast aluminum formulation reacts efficiently in both brackish and saltwater, providing a tighter, more consistent protective barrier than many zinc alternatives. Because the hardware is corrosion-resistant and clearly labeled, replacing anodes becomes a quick maintenance task rather than a frustrating chore.

That smooth installation and tight, secure fitment mean everything stays right where it should, even in rough seas or during long days of hard running.

Why Buy OEM

Choosing a genuine Quicksilver anode kit gives you:

• Marine-tested materials that hold up longer in real-world conditions
• Perfect fitment for your Yamaha outboard—no trimming, forcing, or modifying
• Longer-lasting protection compared to many aftermarket options
• Lower maintenance costs over time
• Confidence backed by Mercury Marine’s decades of engineering expertise

A small investment now keeps your much larger investment protected down the line.
