Sierra 18-6160A Aluminum Anode Kit, Replaces 888761Q01, for Mercruiser Bravo II and Bravo III

The Sierra 18-6160A is an aluminum anode kit engineered as a sacrificial corrosion protection system for Mercruiser Bravo II (1989 and up) and Bravo III (1989-2003) sterndrive units. Aluminum anodes are formulated for brackish water or salt water environments, giving the drive corrosion protection where boats regularly move between fresh and salt water or operate in brackish conditions. The kit installs on the drive to sacrifice itself to galvanic corrosion instead of the more expensive gearcase, housing, and drive components, extending the service life of the sterndrive.

Sierra manufactures this kit to meet or exceed the original equipment part it replaces, and it directly interchanges with the listed OEM Mercruiser numbers below. All Sierra parts are backed by Sierra's industry-leading customer satisfaction warranty. This anode kit is a routine maintenance item that should be inspected and replaced periodically to keep the sacrificial protection active.

Frequently Asked Questions

What does the Sierra 18-6160A anode kit fit? This kit fits Mercruiser Bravo II sterndrives from 1989 and up, and Mercruiser Bravo III sterndrives from 1989-2003.

What material is the 18-6160A anode kit made from? It is made from aluminum, which is designed for brackish water or salt water environments rather than fresh water.

Is aluminum the right anode material for my boat? Aluminum anodes, including the 18-6160A, are intended for brackish water or salt water use; if you run exclusively in fresh water, a magnesium anode kit is the correct choice instead.

What OEM part numbers does the 18-6160A replace? The Sierra 18-6160A cross-references to OEM numbers 888761Q01, 97-888761Q03, and 888761A1 for Mercruiser Bravo II and Bravo III drives.

How much does the 18-6160A anode kit weigh? The Sierra 18-6160A anode kit weighs 2.2 pounds.

Will this kit fit a Bravo I sterndrive? No, the 18-6160A is designated for Bravo II (1989 & up) and Bravo III (1989-2003); a different Sierra kit covers the Bravo I.

Is the Sierra 18-6160A a genuine aftermarket equivalent or OEM? The 18-6160A is manufactured by Sierra as an aftermarket replacement engineered to meet or exceed the original equipment part it replaces.

Why do sterndrives need anode kits like the 18-6160A? Anodes sacrifice themselves to galvanic corrosion so that the drive's gearcase and housing components are protected instead, and the 18-6160A performs this role on Bravo II and Bravo III drives.

How often should the 18-6160A anode kit be replaced? Anode kits such as the 18-6160A should be inspected periodically and replaced once the sacrificial material has significantly wasted away, since a depleted anode no longer protects the drive.

Does the 18-6160A come with a warranty? Yes, the Sierra 18-6160A is covered under Sierra's customer satisfaction warranty like all Sierra parts.

What are the dimensions of the 18-6160A anode kit? The Sierra 18-6160A anode kit measures 0.39 x 0.39 x 0.39 inches.
