Mercury – Quicksilver 823913Q Round Button Style Aluminum Anode | Mercury & Mariner 2.5–40HP Outboards | 823913Q

Overview

Small but essential, the Quicksilver 823913Q Round Button Style Aluminum Anode helps keep your Mercury or Mariner outboard protected from galvanic corrosion. Designed for 1990 and newer 2-stroke 2.5–3.3HP, F2.5–F3.5HP 4-stroke (2006 and newer), and 6–40HP 2-stroke Japanese-built outboards (serial 0N000001 & up), this OEM anode sacrifices itself to protect the key metal components on your engine.

It’s easy to replace, built from high-quality marine aluminum, and works effectively in both freshwater and saltwater. A simple swap during your regular maintenance can extend the life of your motor for years.

Key Features

• Purpose: Shields your outboard from galvanic corrosion by acting as a sacrificial metal.

Performance & Real-World Benefits

The 823913Q anode works as a sacrificial shield — it corrodes first, saving your outboard’s vital parts like the gearcase and mounting hardware from damage. Its round button shape allows for easy access and quick replacement during routine maintenance.

This simple component provides consistent corrosion protection season after season. A few minutes of maintenance can save you from the cost and hassle of repairing pitted or damaged metal surfaces later on.

Why Choose OEM

Mercury’s OEM anodes are made from the precise aluminum blend needed for balanced, long-lasting protection. Aftermarket versions often use mixed or impure metals that wear too fast or unevenly, reducing effectiveness.

A genuine Quicksilver anode ensures proper fit, predictable corrosion control, and the same reliability that Mercury builds into every outboard.
