Sierra 118-6204A Aluminum Power Trim Anode

The Sierra 118-6204A is an aluminum sacrificial anode designed to protect the power trim and tilt components of outboard and stern-drive engines from galvanic corrosion. Sacrificial anodes work by corroding in place of the more valuable metal components they protect, making this a critical maintenance item for any vessel kept in the water for extended periods.

Aluminum anodes are the ideal choice for boaters operating in brackish or salt water environments, offering superior electrochemical protection compared to zinc in many conditions while remaining environmentally responsible. This direct-fit replacement anode is engineered to match OEM specifications, ensuring proper fit and maximum service life.

Key Features:

• Aluminum construction for optimal corrosion protection in salt and brackish water
• Sacrificial anode protects power trim and tilt system components from galvanic corrosion
• Direct OEM-replacement fit for easy installation
• Meets or exceeds original equipment specifications
• Part of Sierra's comprehensive marine corrosion protection line

Replace this anode as part of routine seasonal maintenance — typically when the anode has been reduced to approximately 50% of its original mass. Sierra marine anodes are trusted by boaters and marine technicians worldwide for reliable, long-lasting protection.
