Sacrificial anodes protect the more expensive metal components of an outboard's lower unit and drive system from galvanic corrosion by corroding themselves first, so the anode is designed to be a wear item that is inspected and replaced as it erodes. This anode is manufactured from aluminum and is engineered to meet or exceed original equipment quality, giving boat owners a direct-fit replacement option for the Yamaha applications it covers.\u003c\/p\u003e\u003cp\u003eAnode material matters depending on the water you run in: aluminum anodes like this one are a common choice across fresh, brackish, and salt water use because aluminum corrodes at a controlled rate while offering broad water-type versatility. Regular anode inspection is a standard part of outboard maintenance, and replacing a worn anode with the correct Sierra part helps keep corrosion protection intact for the drive and lower unit.\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 18-6133A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Anode\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Yamaha 150-200 HP Outboards\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Type:\u003c\/strong\u003e 4 Stroke\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Transom Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type:\u003c\/strong\u003e Gasoline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Horsepower:\u003c\/strong\u003e 200 Horsepower\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.7 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282315696\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eYamaha Outboards, 150-200 HP\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-6133A fit?\u003c\/strong\u003e The Sierra 18-6133A is designed to fit Yamaha outboards in the 150-200 HP range.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is this anode made from?\u003c\/strong\u003e This anode is made from aluminum, which offers broad corrosion protection across different water types.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-6133A weigh?\u003c\/strong\u003e The Sierra 18-6133A weighs 1.7 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-6133A a genuine or aftermarket part?\u003c\/strong\u003e The 18-6133A is a Sierra-branded anode manufactured to meet or exceed original equipment quality for the Yamaha 150-200 HP outboards it fits.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat type of engine is the 18-6133A designed for?\u003c\/strong\u003e It is designed for 4 stroke, gasoline-fueled Yamaha outboards in the 150-200 HP range.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the 18-6133A mounted?\u003c\/strong\u003e The 18-6133A uses a transom mounting type.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does an outboard need a sacrificial anode like the 18-6133A?\u003c\/strong\u003e A sacrificial anode corrodes in place of the outboard's more expensive metal components, so installing an anode such as the 18-6133A protects the lower unit and drive from galvanic corrosion.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow often should the 18-6133A be replaced?\u003c\/strong\u003e Anodes like the 18-6133A are wear items that should be inspected regularly and replaced once they have significantly eroded, since a depleted anode no longer provides effective corrosion protection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when ordering the 18-6133A?\u003c\/strong\u003e Ordering the 18-6133A includes one aluminum anode for Yamaha 150-200 HP outboards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the maximum horsepower rating limit which Yamaha outboards this anode fits?\u003c\/strong\u003e The 18-6133A is rated up to 200 horsepower and fits within the Yamaha 150-200 HP outboard range.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988353429723,"sku":"SIE-18-6133A","price":48.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-6133A__66140.1558185699.500.750.jpg?v=1785189041","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-6133a-aluminum-anode-for-yamaha-150-200-hp-outboards","provider":"Good Vibes Marina","version":"1.0","type":"link"}
