As the least noble metal in the system, the zinc anode corrodes preferentially, sacrificing itself so that the more critical engine, drive, and hardware components are preserved. This is a transom-mount anode intended for use on 4-stroke gasoline outboard engines.\u003c\/p\u003e\u003cp\u003eThe anode is a direct equivalent for the Yamaha 688-45371-02-00 and Mercury Marine 97-826134Q part numbers, allowing it to be installed as a like-for-like replacement without modification. It ships as a single unit and is manufactured to meet or exceed the performance of the original equipment part it replaces. As with all sacrificial anodes, periodic inspection is recommended, with replacement needed once roughly half of the original material has been consumed, to maintain continuous corrosion protection for the connected components.\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 18-6070\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Yamaha Outboard Anode\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Zinc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.22 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Transom Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Type:\u003c\/strong\u003e 4 Stroke\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type:\u003c\/strong\u003e Gasoline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999976819\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits Yamaha outboard engines specified for the 688-45371-02-00 anode.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury Marine 97-826134Q\u003c\/li\u003e\n\u003cli\u003eYamaha 688-45371-02-00\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-6070 used for?\u003c\/strong\u003e It is a zinc sacrificial anode that protects submerged outboard engine and drive components from galvanic corrosion by corroding in place of the more critical metal parts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-6070 a direct replacement for the Yamaha 688-45371-02-00?\u003c\/strong\u003e Yes, the Sierra 18-6070 is a direct equivalent for the Yamaha 688-45371-02-00 anode and installs as a like-for-like replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-6070 cross reference to a Mercury Marine part number?\u003c\/strong\u003e Yes, the Sierra 18-6070 also cross-references to Mercury Marine part number 97-826134Q.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Sierra 18-6070 anode made from?\u003c\/strong\u003e Zinc, which is the standard sacrificial metal used for anodes on outboards operated in saltwater and brackish water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-6070 weigh?\u003c\/strong\u003e The Sierra 18-6070 anode weighs 1.22 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the Sierra 18-6070 mounted?\u003c\/strong\u003e It is a transom-mount anode designed to attach to the transom area of the outboard.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat engine type is the Sierra 18-6070 designed for?\u003c\/strong\u003e It is designed for 4-stroke gasoline outboard engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many anodes come in one Sierra 18-6070 package?\u003c\/strong\u003e The Sierra 18-6070 is sold as a single unit, with one anode per package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-6070 genuine Sierra or aftermarket?\u003c\/strong\u003e The 18-6070 is a genuine Sierra part, manufactured to meet or exceed the performance of the original equipment anode it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should the Sierra 18-6070 anode be replaced?\u003c\/strong\u003e Like any sacrificial anode, the 18-6070 should be inspected periodically and replaced once a significant portion of its original zinc material has corroded away, to keep protecting the connected components.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-6070 anode?\u003c\/strong\u003e The Sierra 18-6070 is white in color.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988350152923,"sku":"SIE-18-6070","price":21.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-6070_lg__98361.1558128772.500.750.jpg?v=1785188499","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-6070-zinc-anode-for-yamaha-60-70-90-hp-outboards-replaces-oem-688-45371-02-00-lower-casing-drive","provider":"Good Vibes Marina","version":"1.0","type":"link"}
