Sierra 18-6126M Magnesium Transom Anode with Bolt for Volvo Penta Stern Drives Anodes/Zincs

The Sierra 18-6126M is a magnesium transom anode with mounting bolt, engineered as a direct replacement for Volvo Penta stern drive applications. Sacrificial anodes like this one protect your boat's underwater metal components from galvanic corrosion, extending the life of expensive drive hardware.

Important: Magnesium anodes are formulated exclusively for freshwater use only. Do not use in saltwater or brackish water environments — choose zinc (saltwater) or aluminum (brackish/mixed water) anodes for those conditions.

Key Features:

• Material: High-purity magnesium construction optimized for freshwater corrosion protection
• Compatibility: Designed for Volvo Penta SX-A, DPS-A, and DPS-A Oxi stern drives
• OEM Replacement: Direct replacement for Volvo Penta OEM part number 3888818
• Complete Kit: Includes one transom anode and two mounting bolts per package
• OEM Quality: Meets or exceeds the performance of the original equipment part it replaces

Sierra International is a leading manufacturer of marine replacement parts. The 18-6126M is also available in zinc (18-6126Z) for saltwater and aluminum (18-6126A) for brackish or mixed-water use, allowing boaters to select the correct anode material for their operating environment.
