Anodes should also be inspected during spring commissioning, fall haul-out, winterization, gear lube service, propeller service, and any time corrosion, bubbling paint, white powdering, or unusual metal loss is seen on the drive.\u003c\/p\u003e\n\u003cp\u003eDo not wait until an anode is completely gone. Once the sacrificial metal is consumed, the sterndrive housing and underwater hardware become the next corrosion target.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eInstallation Notes\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eRemove the old anodes and clean each mounting surface down to bare metal before installing the new zincs. Sacrificial anodes must have direct metal-to-metal contact with the drive to work properly. Paint, corrosion, marine growth, sealant, or heavy scale under the anode can insulate it and prevent proper protection.\u003c\/p\u003e\n\u003cp\u003eDo not paint anodes. Antifouling paint, primer, clear coat, or heavy coating over the zinc surface prevents the water from contacting the sacrificial metal and can stop the anode from working. Tighten mounting hardware securely and inspect bonding continuity where applicable.\u003c\/p\u003e\n\u003cp\u003eAfter installation, recheck the anodes after the boat has been back in the water, especially if the vessel is kept in a marina with shore power, nearby steel pilings, or known stray-current issues.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAlternate\/Cross-Reference Part Numbers\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlpha1G2-Kit-ZN\u003c\/strong\u003e — zinc anode kit part number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMercury\/Quicksilver 97-888756Q03\u003c\/strong\u003e — OEM anode kit reference; verify by drive serial number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMercury\/Quicksilver 888756Q01\u003c\/strong\u003e — OEM anode kit reference; verify by drive serial number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMartyr ALPHAKITZ\u003c\/strong\u003e — zinc kit reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMartyr CMALPHAKITZ\u003c\/strong\u003e — zinc kit reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSierra 18-6158Z\u003c\/strong\u003e — zinc kit reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTecnoseal 20801\u003c\/strong\u003e — zinc kit reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e821631\u003c\/strong\u003e — gimbal housing block anode reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e821629\u003c\/strong\u003e — ventilation plate anode reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e76214-5\u003c\/strong\u003e — trim tab\/skeg anode reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e806105\u003c\/strong\u003e — bearing carrier collar anode reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e806189\u003c\/strong\u003e — trim cylinder ram collar anode reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eParts Desk Insight\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eAlpha One Gen II anodes should be selected by both \u003cstrong\u003edrive model\u003c\/strong\u003e and \u003cstrong\u003ewater type\u003c\/strong\u003e. Zinc is the traditional saltwater choice, but it is not the best material for every boating environment. The cleanest installation is one where every anode contacts bare metal, all hardware is tight, and no anode is painted or insulated from the drive. When corrosion is already visible, inspect the bonding system, shore power ground, drive paint, trim rams, prop hardware, and nearby marina conditions as part of the repair.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e Ships same or next day for fast Canada wide shipping. ⚓\u003c\/p\u003e","brand":"MDL","offers":[{"title":"Default Title","offer_id":43563836407844,"sku":"A1G2KZ","price":98.86,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/73e6e525-7005-4461-a440-7b56a28c2c3d.png?v=1781219508","url":"https:\/\/marisolmarine.com\/products\/mdl-4","provider":"Marisol Marine Company","version":"1.0","type":"link"}
