This complete zinc\/brass style prop nut anode is intended to help protect the propeller nut and nearby running gear from galvanic corrosion in saltwater service. Zinc construction is intended for saltwater use only. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"492\" data-end=\"506\"\u003eKey Features\u003c\/p\u003e\n\u003cul data-start=\"507\" data-end=\"793\"\u003e\n\u003cli data-start=\"507\" data-end=\"548\"\u003eComplete propeller nut anode assembly\u003c\/li\u003e\n\u003cli data-start=\"549\" data-end=\"584\"\u003e1\/2\"-13 NC thread specification\u003c\/li\u003e\n\u003cli data-start=\"585\" data-end=\"626\"\u003eZinc anode material for saltwater use\u003c\/li\u003e\n\u003cli data-start=\"627\" data-end=\"660\"\u003eBrass prop nut style assembly\u003c\/li\u003e\n\u003cli data-start=\"661\" data-end=\"793\"\u003eDesigned to provide sacrificial corrosion protection for propeller hardware and running gear \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"795\" data-end=\"1186\"\u003eEngine Compatibility\u003cbr data-start=\"815\" data-end=\"818\"\u003eSuitable for shaft-driven propeller applications that specifically require a propeller nut anode assembly in Pattern A with 1\/2\"-13 NC threading. Because prop nut anodes are pattern- and thread-specific, fitment should be confirmed by shaft thread, nut style, propeller hub clearance, and the existing anode shape before ordering. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"1188\" data-end=\"1456\"\u003eSerial Number Fitment Notice\u003cbr data-start=\"1216\" data-end=\"1219\"\u003eFitment should be confirmed by the installed propeller nut assembly dimensions and shaft thread specification rather than engine family alone.

As a general service rule, sacrificial anodes should be replaced before they are fully consumed. One marine catalog reference advises checking anodes regularly and replacing them when they are about 70% consumed. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"1844\" data-end=\"2220\"\u003eInstallation Notes\u003cbr data-start=\"1862\" data-end=\"1865\"\u003eInstall only on applications that call for a 1\/2\"-13 NC prop nut anode assembly. Clean mating surfaces before installation so the anode can maintain proper electrical contact. Verify propeller retention hardware, thread engagement, and clearance after installation. Zinc anodes are not recommended for freshwater use. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"2222\" data-end=\"2259\"\u003eAlternate \/ Superseded Part Numbers\u003c\/p\u003e\n\u003cul data-start=\"2260\" data-end=\"2323\"\u003e\n\u003cli data-start=\"2260\" data-end=\"2271\"\u003ePNAZC13\u003c\/li\u003e\n\u003cli data-start=\"2272\" data-end=\"2323\"\u003eCMT-PNAZC13 \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"2325\" data-end=\"2702\"\u003eParts Desk Insight\u003cbr data-start=\"2343\" data-end=\"2346\"\u003eProp nut anodes are one of the more application-specific sacrificial anodes on a boat. Matching the thread and nut pattern is just as important as matching the anode material. For boats kept in saltwater, zinc remains a common choice, while aluminum is generally preferred for many saltwater and brackish applications. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"2704\" data-end=\"2780\"\u003eShipping\u003cbr data-start=\"2712\" data-end=\"2715\"\u003eShipping: Ships same or next day for fast Canada wide shipping. ⚓\u003c\/p\u003e","brand":"WEST","offers":[{"title":"Default Title","offer_id":43564134072356,"sku":"CMT-PNAZC13","price":47.09,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/2c0ab2b5-e094-40ab-aaf9-b18a6b9da1ec.png?v=1775436714","url":"https:\/\/marisolmarine.com\/products\/zinc-propeller-nut-assembly-a-half-nc13-cmt-pnazc13","provider":"Marisol Marine Company","version":"1.0","type":"link"}
