How to choose accurately
Only products with documented manufacturer applications or confirmed selection dimensions appear in this finder. Read the exact application and every stated limit. A shared engine brand or horsepower alone is not sufficient. Match the equipment serial number, original anode shape, hole spacing, thread and dimensions. Kits are not interchangeable merely because they share a component reference.
Match the alloy of your other anodes on the same bonded system. Do not mix zinc, aluminum and magnesium unless the equipment manufacturer specifies otherwise. Zinc is for saltwater; magnesium is for freshwater only; aluminum is commonly used in saltwater / brackish water, with product-specific freshwater exceptions. Performance Metals lists Navalloy aluminum for all three water types. Follow your equipment manufacturer’s requirements.
Fitment choices come from exact manufacturer part records, product pages, service manuals and catalog rows. Products without adequate evidence are excluded while we verify them. This finder does not cover every engine model. Prices and availability are checked live when results appear. Sold-out products are included and labeled. Draft and unpublished products are excluded.
