Zinc anodes work by corroding preferentially to the surrounding metal components, so as long as the anode is present and in contact with the gearcase, it takes the corrosive damage instead of the propeller shaft, housing, and other submerged metal parts. This makes routine anode replacement one of the most important and cost-effective maintenance tasks for any outboard-powered boat.\u003c\/p\u003e\u003cp\u003eThis anode is designed for 1982-1987 outboards in the 60-300 HP range and mounts directly to the gearcase. It is manufactured from zinc for reliable sacrificial performance and is built to meet or exceed the specification of the original equipment part it replaces. Boat owners running outboards in this horsepower and year range can use the 18-6095 as a direct replacement without modification.\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 18-6095\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Zinc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Use On:\u003c\/strong\u003e Gearcases\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorsepower Range:\u003c\/strong\u003e 60-300 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYears:\u003c\/strong\u003e 1982-1987\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.61 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282237363\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross-Reference:\u003c\/strong\u003e 393023, 436745\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e1982-1987 outboards, 60-300 HP, gearcase mount\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e393023\u003c\/li\u003e\n\u003cli\u003e436745\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-6095 anode fit?\u003c\/strong\u003e The Sierra 18-6095 is designed for gearcase mounting on 1982-1987 outboards rated 60-300 HP.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the 18-6095 replace?\u003c\/strong\u003e This zinc anode replaces OEM numbers 393023 and 436745.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-6095 anode made from?\u003c\/strong\u003e Zinc.
