The Martyr Anodes CM393023A is a direct replacement sacrificial anode designed specifically for BRP (OMC/Johnson/Evinrude) outboard motors. This anode protects your engine's critical metal components from galvanic corrosion by sacrificing itself to prevent deterioration of more expensive parts like the engine block, gearcase, and cooling system components.

Key Features:

• Direct replacement for OEM part number 393023
• Precision-engineered to exact OEM specifications for proper fit and function
• Available in three alloy options for different water conditions
• Manufactured to stringent military specifications for reliable corrosion protection
• Easy installation with OEM mounting configuration

Material Selection Guide:

• Zinc Alloy: Recommended for use in salt water environments
• Aluminum Alloy: Ideal for brackish water (mixed salt and fresh water)

Regular inspection and replacement of sacrificial anodes is essential preventive maintenance that protects your investment and extends the life of your outboard motor. Replace anodes when they have eroded to approximately 50% of their original size for optimal protection.
