Seachoice Hull Plate Anode Z406 – Zinc | Saltwater & Brackish Water
The Seachoice Hull Plate Anode Z406 is a zinc sacrificial anode designed to mount directly to the hull of a vessel for broad galvanic corrosion protection in saltwater and brackish water environments. The large flat plate profile provides substantial anode mass for extended protection between replacements, making it well suited to larger vessels, steel or aluminum hulls, and any application where maximum hull coverage is needed.
Zinc is the standard anode material for saltwater and brackish water use, providing reliable galvanic protection for steel and aluminum hulls in marine environments. All mounting hardware is included for a straightforward installation.
Key Features
- Zinc construction — correct material for saltwater and brackish water use
- Cadmium-free formulation
- Large plate profile for broad hull coverage and extended service life
- All mounting hardware included
- Suitable for steel and aluminum hulls in saltwater and brackish water
Compatible Applications
- Steel and aluminum-hulled vessels in saltwater and brackish water
- Larger inboard and shaft-drive vessels requiring broad hull anode coverage
- Coastal and offshore vessels, marina-kept boats, and commercial vessels

Parts Desk Insights
The Seachoice Hull Plate Anode Z406 is best suited for saltwater and brackish water vessel owners — particularly those with steel or aluminum hulls — who need a large, flat zinc anode that mounts directly to the hull for broad galvanic protection. The Z406 is a substantial anode by weight, providing meaningful service life between replacements on larger vessels. Zinc is the standard choice for saltwater hull plate anodes; it provides reliable protection in the higher conductivity of marine water. If you operate in freshwater, use the magnesium version instead: Seachoice Hull Plate Anode – 12" × 5" × ½", Magnesium. For shaft anodes, see the Seachoice Streamlined Shaft Anode – 2" (Model X9), Magnesium, 1¼" (Model X5), and 1½" (Model X7).
