Sierra 18-6115 Zinc Anode Transom Bracket for Johnson/Evinrude Outboards

The Sierra 18-6115 is a zinc sacrificial anode designed specifically for transom bracket installation on Johnson/Evinrude outboard motors. This critical corrosion protection component directs galvanic corrosion away from vital engine parts such as shafts, propellers, rudders, and drive components, causing the anode itself to corrode instead of the expensive engine hardware.

Key Features:

• Zinc alloy construction for superior corrosion protection in saltwater environments
• Designed for use on stern brackets of Johnson/Evinrude 60-225 HP outboards (1991-1993)
• Direct replacement for OEM part numbers 433580 and 5007089
• Manufactured to meet or exceed original equipment specifications
• Easy installation with screw-on or bolt-on mounting

Application Notes:

This zinc anode is formulated specifically for saltwater use only. For brackish water applications, aluminum anodes are recommended, while magnesium anodes should be used in freshwater environments. Regular inspection and replacement of sacrificial anodes is essential for maintaining proper corrosion protection and extending the life of your marine engine components.
