Yamaha - Cylinder Head Anode - Corrosion Protection - 67F-11301-00-00 / 67F-11301-01-00

Overview

Corrosion protection inside a Yamaha outboard is something experienced boaters never ignore. The Yamaha Cylinder Head Anode 67F-11301-00-00 / 67F-11301-01-00 is designed to absorb electrolysis before it can attack the engine’s internal metal surfaces. Instead of letting corrosion damage cooling passages and engine components, this anode sacrifices itself first. It’s a small part, but it plays a big role in protecting the engine over time.

Key Features

• Sacrificial Corrosion Protection – Draws electrolysis away from internal engine components to prevent corrosion damage.

• OEM Yamaha Engineering – Manufactured to Yamaha specifications for proper fit and dependable corrosion control.

• Cylinder Head Protection – Helps safeguard cooling passages and internal metal surfaces exposed to water.

• Marine Environment Durability – Built to perform in saltwater and harsh marine operating conditions.

• Routine Maintenance Component – Designed to be inspected and replaced during scheduled engine service.

Engine & Boat Compatibility
