This split collar shaft anode helps protect propeller shafts and nearby running gear from galvanic corrosion in saltwater service. It is commonly listed with a 7\/8\" inside diameter, 2-1\/8\" outside diameter, and 1\" length. Zinc is intended for saltwater use only. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"511\" data-end=\"525\"\u003eKey Features\u003c\/p\u003e\n\u003cul data-start=\"526\" data-end=\"866\"\u003e\n\u003cli data-start=\"526\" data-end=\"571\"\u003eZinc limited-clearance shaft collar anode\u003c\/li\u003e\n\u003cli data-start=\"572\" data-end=\"596\"\u003eFits 7\/8\" shaft size\u003c\/li\u003e\n\u003cli data-start=\"597\" data-end=\"656\"\u003eApproximate dimensions: 7\/8\" ID x 2-1\/8\" OD x 1\" length\u003c\/li\u003e\n\u003cli data-start=\"657\" data-end=\"703\"\u003eSplit collar design for shaft installation\u003c\/li\u003e\n\u003cli data-start=\"704\" data-end=\"759\"\u003eCommonly listed with Allen screw fastening hardware\u003c\/li\u003e\n\u003cli data-start=\"760\" data-end=\"866\"\u003eDesigned for propeller shaft and running gear corrosion protection \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"868\" data-end=\"1262\"\u003eEngine Compatibility\u003cbr data-start=\"888\" data-end=\"891\"\u003eThis is not an engine-specific anode. It is a shaft-size-based replacement part for vessels using a 7\/8\" propeller shaft and the matching limited-clearance collar anode format. Fitment should be confirmed by shaft diameter, anode outside diameter, available clearance around the shaft, and the installed collar style before ordering. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"1264\" data-end=\"1569\"\u003eSerial Number Fitment Notice\u003cbr data-start=\"1292\" data-end=\"1295\"\u003eFitment should be confirmed by shaft size and anode dimensions rather than engine serial number alone.

This split collar style is designed for easy installation, including underwater replacement in suitable service conditions, and some listings note retaining washers to help keep the halves in place during installation. Confirm full contact on the shaft and adequate clearance around the rotating assembly after installation. Zinc is for saltwater use and is not recommended for freshwater service. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"2445\" data-end=\"2482\"\u003eAlternate \/ Superseded Part Numbers\u003c\/p\u003e\n\u003cul data-start=\"2483\" data-end=\"2634\"\u003e\n\u003cli data-start=\"2483\" data-end=\"2492\"\u003eCMC02\u003c\/li\u003e\n\u003cli data-start=\"2493\" data-end=\"2504\"\u003eCMT-C02\u003c\/li\u003e\n\u003cli data-start=\"2505\" data-end=\"2518\"\u003e194-CMC02\u003c\/li\u003e\n\u003cli data-start=\"2519\" data-end=\"2530\"\u003e22-3180\u003c\/li\u003e\n\u003cli data-start=\"2531\" data-end=\"2553\"\u003eSea Shield LC-0875\u003c\/li\u003e\n\u003cli data-start=\"2554\" data-end=\"2579\"\u003eElectro Guard LC-0875\u003c\/li\u003e\n\u003cli data-start=\"2580\" data-end=\"2634\"\u003eReliance MDC-2 \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"2636\" data-end=\"3006\"\u003eParts Desk Insight\u003cbr data-start=\"2654\" data-end=\"2657\"\u003eThis is a limited-clearance shaft anode, which matters when space around the shaft is tight. On these collar anodes, the safest match is the shaft diameter first, then the outside diameter and overall length, because a wrong outside diameter can create clearance problems even when the shaft size looks correct. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"3008\" data-end=\"3084\" data-is-last-node=\"\" data-is-only-node=\"\"\u003eShipping\u003cbr data-start=\"3016\" data-end=\"3019\"\u003eShipping: Ships same or next day for fast Canada wide shipping. ⚓\u003c\/p\u003e","brand":"WEST","offers":[{"title":"Default Title","offer_id":43564131418148,"sku":"CMT-C02","price":19.21,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/s-l400_1.jpg?v=1775444156","url":"https:\/\/marisolmarine.com\/products\/zinc-shaft-collar-anode-7-8-id-cmt-c02","provider":"Marisol Marine Company","version":"1.0","type":"link"}
