Cylinder Anode - Zinc - For Yamaha F9.9-F350 Part # 6E5-11325-00-00

Cylinder Anode - Zinc for Yamaha

This cylinder anode is a sacrificial zinc component used to prevent galvanic corrosion in Yamaha outboard engines. Designed to replace OEM part number 6E5-11325-00-00, it protects the cylinder head and block from electrolytic damage.

Overview

This cylinder anode is a premium replacement zinc anode formulated for Yamaha outboard motors. It actively corrodes in place of aluminum engine parts, extending the life of critical cooling passages and cylinder surfaces. Suitable for Yamaha engines from 9.9 hp to 350 hp, this anode ensures reliable corrosion protection in marine environments.

Built For Performance

• High-purity zinc alloy meets MIL-A-18001 specification
• Precise fitment prevents loose installation and vibration
• Sacrificial protection reduces pitting and cavitation damage
• Pre-drilled mounting holes match OEM spacing
• Corrosion-resistant hardware included for secure attachment

Fits These Machines

• for Yamaha outboard models F9.9 through F350

On-The-Job Use

• Annual replacement during winterization or spring service
• Saltwater operation where electrolysis risk is highest
• After any repair involving engine disassembly and coolant exposure
• Freshwater use to maintain neutral electrical potential

Good To Know

Q: How do I know when to replace the zinc anode? A: Replace the anode when it has corroded to less than 50% of its original mass or if it shows significant pitting, typically once per season.

Q: Can I use this anode in brackish water? A: Yes, zinc anodes are effective in both saltwater and brackish environments; for freshwater only, magnesium anodes are recommended instead.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
