Sacrificial anodes protect the more expensive metal components of a sterndrive from galvanic corrosion by corroding first, so replacing worn anodes on a regular schedule is one of the simplest ways to extend the service life of the drive. This kit uses aluminum anode material, which is a common choice for boats operating in brackish or fresh water as well as salt water.\u003c\/p\u003e\u003cp\u003eSierra manufactures this kit to meet or exceed the performance of the original equipment it replaces, and every Sierra part is backed by Sierra's customer satisfaction warranty. Sierra supplies OEM engine manufacturers and boat builders with parts daily, so the fit and finish are built to marine duty-cycle standards.\u003c\/p\u003e\u003cp\u003eThis anode kit is intended for Mercruiser Bravo I sterndrives, across all years of that drive. Boat owners should inspect anodes periodically and replace them once they are worn down significantly, since a depleted anode can no longer protect the drive's metal components from corrosion.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-6159A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Anode Kit Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.34 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282277284\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Mercruiser Anodes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercruiser Bravo I sterndrives, all years\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-6159A anode kit fit?\u003c\/strong\u003e The Sierra 18-6159A Anode Kit is designed for Mercruiser Bravo I sterndrives, covering all years of that drive.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-6159A anode kit made from?\u003c\/strong\u003e This kit is made from aluminum, a sacrificial anode material commonly used to protect sterndrives from galvanic corrosion in salt, brackish, and fresh water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-6159A anode kit weigh?\u003c\/strong\u003e The Sierra 18-6159A Anode Kit weighs 2.34 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-6159A an OEM or aftermarket part?\u003c\/strong\u003e It is a Sierra-manufactured aftermarket anode kit engineered to meet or exceed the performance of the original equipment it replaces on Mercruiser Bravo I sterndrives.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy do sterndrives need anode kits like the 18-6159A?\u003c\/strong\u003e Sacrificial anodes such as the 18-6159A corrode in place of the more expensive metal components on a Bravo I sterndrive, protecting the drive from galvanic corrosion.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow often should the 18-6159A anode kit be replaced?\u003c\/strong\u003e Anodes should be inspected regularly and the 18-6159A kit replaced once the aluminum anodes are visibly worn down, since a depleted anode no longer protects the sterndrive.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-6159A anode kit have a warranty?\u003c\/strong\u003e Yes, the Sierra 18-6159A Anode Kit is covered under Sierra's customer satisfaction warranty, as are all Sierra parts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat finish does the 18-6159A anode kit have?\u003c\/strong\u003e The Sierra 18-6159A Anode Kit has a machined finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-6159A anode kit only for saltwater boats?\u003c\/strong\u003e No, the aluminum construction of the 18-6159A anode kit makes it suitable for boats run in salt, brackish, or fresh water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-6159A anode kit?\u003c\/strong\u003e The UPC for the Sierra 18-6159A Anode Kit is 808282277284.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988354347227,"sku":"SIE-18-6159A","price":82.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/sie-18-6159a_lg__63695.1558145817.500.750.jpg?v=1785188236","url":"https:\/\/www.goodvibesmarina.com\/products\/aluminum-anode-kit-for-mercruiser-alpha-i-gen-ii-1991-up-replaces-oem-888758q01-sierra-18-6159a","provider":"Good Vibes Marina","version":"1.0","type":"link"}
