Sierra 18-6160Z Zinc Anode Kit for Mercruiser Bravo I, Bravo II (1989 & Up), Bravo III (1989-03)

The Sierra 18-6160Z Anode Kit is a zinc sacrificial anode set engineered for saltwater-only use on Mercruiser Bravo sterndrives. Zinc anodes corrode preferentially to the drive's running gear, protecting expensive components such as the gear housing and drive shaft from galvanic corrosion in saltwater environments. This kit is designed to fit Mercruiser Bravo I - All Years, Bravo II (1989 & Up), and Bravo III (1989-03) sterndrives.

Sierra manufactures this anode kit to meet or exceed the specifications of the original equipment part it replaces, and supplies many OEM engine manufacturers and boat builders with parts daily. For boaters running in fresh water, Sierra offers the same kit in magnesium (18-6160M), and for brackish or salt water environments, an aluminum version (18-6160A) is also available, so you can match the anode material to your boating environment.
