The Volvo Penta 828140 Zinc Anode is a vital protective component specifically designed for marine propeller shafts. This zinc anode, intended for use with 40mm and 45mm diameter shafts, effectively mitigates galvanic corrosion, a common issue in saltwater environments. The anode threads onto the propeller shaft with a 1-inch UNC thread, providing easy and secure installation, and works by sacrificing itself to corrosive elements, which preserves essential metal components such as the propeller and outdrive.
The 828140 zinc anode is an OEM product from Volvo Penta, ensuring compatibility and performance with original engine setups. Regular replacement of this sacrificial anode helps avoid costly repairs and maintain optimal performance in high-salinity waters.
Key Features:
- Original Equipment Manufacturer (OEM): Genuine Volvo Penta product ensures compatibility and quality.
- Corrosion Protection: Sacrificial anode for effective defense against galvanic corrosion.
- Durable Zinc Composition: Engineered for saltwater applications, providing a longer lifespan for key components.
- Compatibility: Fits 40mm and 45mm propeller shafts with 1” UNC thread.
- Easy Installation: Straightforward fitting and replacement on Volvo Penta systems.
Volvo Penta is a global leader in marine propulsion solutions, delivering high-quality and reliable parts to enhance vessel performance. Known for their durable OEM components, Volvo Penta parts like the 828140 zinc anode ensure robust protection and longevity for marine equipment in saltwater environments.
