B & S Anodes BSMM43994 Zinc Trim Tab Anode for Mercury Outdrives

The B & S Anodes BSMM43994 is a zinc trim tab anode designed specifically for Mercury outdrives and outboard motors. This sacrificial anode provides critical corrosion protection for your lower unit by attracting electrolysis and preventing damage to expensive drive components.

Key Features:

• Premium zinc construction for maximum corrosion protection in saltwater and brackish water environments
• Direct replacement trim tab anode for Mercury marine applications
• Designed to mount on the anti-ventilation plate (trim tab area) of the lower unit
• Sacrificial design protects propeller, shaft, and other critical metal components from galvanic corrosion
• Easy bolt-on installation with standard hardware

Important Installation Note: Always verify proper propeller clearance after installing new trim tab anodes to ensure safe operation and prevent contact during engine operation.

Regular replacement of sacrificial anodes is essential maintenance for any boat operating in saltwater or brackish water. These anodes should be inspected regularly and replaced when 50% depleted to maintain optimal corrosion protection for your Mercury outdrive system.
