Sacrificial anodes protect the more critical, and more expensive, metal components of your outboard from galvanic corrosion by corroding themselves first. As an aluminum anode, the 18-6090 is intended for brackish water use, or for boats that operate in both fresh and salt water environments, giving it broader application than a single-environment zinc or magnesium anode. It directly replaces OEM part number 6G5-45251-01-00, so it installs as a direct fit in place of the original transom bracket anode without modification. Regular anode inspection and replacement is one of the simplest ways to protect an outboard's lower unit and bracket hardware from corrosion damage, and choosing the correct anode material for your water conditions is essential to getting the protection you expect. The 18-6090 weighs 0.93 pounds and is sold as a single anode.

Magnesium anodes are the correct choice for freshwater use, where their higher reactivity provides more effective protection than zinc, sacrificing itself first to keep the surrounding metal components of the outboard from corroding. Installing the correct anode material for your operating water is one of the simplest and most cost-effective ways to extend the service life of an outboard's underwater metal parts.\u003c\/p\u003e\u003cp\u003eThis anode is a direct fit for the OEM location it replaces, allowing straightforward swap-out during routine maintenance without modification.

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"},{"product_id":"sierra-18-6136-zinc-sacrificial-anode-2-in-x-3-8-in-marine-corrosion-protection","title":"Sierra 18-6136 Zinc Anode for PleasureCraft Engines, 3\/8 Inch","description":"\u003cp\u003eThe Sierra 18-6136 is a zinc sacrificial anode built for PleasureCraft engine applications.

Zinc anodes are the standard choice for boats operated in saltwater, where they sacrifice themselves to protect surrounding metal from electrolysis and galvanic corrosion. Routine anode inspection and replacement is a core part of sterndrive maintenance, and a worn anode (more than 50 percent consumed) should be replaced promptly to keep the protection system effective.

Sacrificial anodes work by corroding preferentially in place of more critical metal parts such as outdrives, propellers, and running gear, giving boat owners a low-cost, replaceable line of defense against electrolysis damage. Aluminum anodes are a common choice for boats that operate across a range of water conditions, since aluminum offers broader corrosion protection versatility than single-environment anode materials. As the anode material wears down over time through normal galvanic activity, it should be inspected periodically and replaced once it has worn away significantly, helping prevent costly corrosion damage to the boat's underwater metal components.
