Performance Metals Yamaha 300-425HP Aluminum Anode Kit

The Performance Metals Yamaha 300-425HP Aluminum Anode Kit is designed for Yamaha 300-425 HP outboards. It uses Navalloy aluminum sacrificial material manufactured to MIL-DTL-24779, giving the anode or kit a defined marine alloy specification rather than relying on a generic aluminum formulation. Navalloy is suitable for saltwater, brackish water, and freshwater, which makes these parts practical for boats that operate or move between different water environments. The two-piece kit provides the specified sacrificial components for high-horsepower Yamaha outboard service.

The package includes 00357A, quantity 1, replacing Yamaha 6AW-45251-00 and 00358A, quantity 1, replacing Yamaha 6AW-45373-00. Together, these details make it easier to match the replacement to the existing application and complete routine corrosion-protection service with the correct components. Browse more marine anodes.
