Martyr Anodes CM398873A Replacement Anode for BRP OMC Johnson Evinrude Outboards

The Martyr Anodes CM398873A is a direct replacement sacrificial anode designed specifically for BRP (OMC/Johnson/Evinrude) outboard motors. This precision-engineered anode protects your engine's critical metal components from galvanic corrosion by sacrificing itself to prevent deterioration of more expensive engine parts.

Key Features:

• Direct OEM replacement for BRP part number 398873
• Precision cast to exact specifications for proper fit and function
• Available in multiple alloy types to match your water conditions
• Easy installation with no modifications required
• High-purity alloy composition for maximum corrosion protection

Material Selection by Water Type:

• Zinc Alloy: Designed for use in salt water environments where zinc provides optimal galvanic protection
• Aluminum Alloy: Recommended for brackish water conditions where mixed salinity requires aluminum's versatile protection properties
• Magnesium Alloy: Engineered for fresh water applications where magnesium offers the highest level of protection

Regular replacement of sacrificial anodes is essential preventive maintenance that extends the life of your outboard motor by protecting expensive engine components like the lower unit, trim tabs, and cooling system from corrosion damage. Inspect anodes regularly and replace when 50% depleted for continuous protection.
