Sierra 18-6016 Aluminum Anode - Replaces 76214, Fits Mercury 200-250HP, V-155-V-200 & All Bravo Drives

The Sierra 18-6016 is an aluminum sacrificial anode built to protect Mercury outboard and sterndrive metal components from galvanic corrosion. Aluminum anodes are designed for brackish or salt water environments, where they corrode in place of more expensive engine and drive components, extending the service life of the powerhead, gearcase, and other submerged metal parts. As the anode sacrifices itself to electrolysis, it should be inspected regularly and replaced once it has worn down significantly, since a depleted anode can no longer protect the surrounding metal.

This anode is a direct cross-reference replacement for several Mercury OEM part numbers, so it installs in place of the original equipment anode without modification. It is designed to fit Mercury 200, 225, and 250 HP outboards, the V-155-V-200 engine range, and all Bravo sterndrives.

Frequently Asked Questions

What is the Sierra 18-6016 anode made of? The 18-6016 is an aluminum anode, which is recommended for brackish water or salt water environments rather than fresh water.

Will this anode work in fresh water? No. The 18-6016 is an aluminum anode intended for brackish or salt water use; magnesium anodes are the correct choice for fresh water only applications.

What engines does the Sierra 18-6016 fit? It fits Mercury 200, 225, and 250 HP engines, the V-155-V-200 range, and all Bravo sterndrives.

What OEM part numbers does 18-6016 replace? The 18-6016 cross-references to OEM numbers 76214, 97-76214Q5, 97-762145, 76214A5, 786214A2, 762142, and 762142A1, so any of those original part numbers can be replaced with this anode.

How much does the 18-6016 anode weigh? It weighs 0.67 pounds.

What are the dimensions of this anode? The Sierra 18-6016 measures 1 inch in length, 1 inch in width, and 1 inch in height.

Is the 18-6016 a genuine Sierra part or aftermarket equivalent? It is manufactured and sold under the Sierra brand as part number 18-6016, functioning as a direct cross-reference replacement for the listed Mercury OEM anode numbers.

How do I know when to replace this anode? Since the 18-6016 is a sacrificial anode, it should be inspected periodically and replaced once it has visibly corroded down, as a worn anode can no longer protect the surrounding metal components from galvanic corrosion.

Does all Bravo sterndrive series use this anode? Yes, the Sierra 18-6016 is listed as fitting all Bravo sterndrives, in addition to Mercury 200-250 HP engines and the V-155-V-200 range.

What is included when I order the 18-6016? Each order includes one Sierra 18-6016 aluminum anode.

Why does anode material matter for corrosion protection? Anode material must match the water environment: aluminum anodes like the 18-6016 are for brackish or salt water, zinc anodes are for saltwater only, and magnesium anodes are for fresh water only, since using the wrong material reduces corrosion protection.
