Alpha One Gen I and Alpha One Gen II anode kits are not the same.

Anodes should be inspected during spring commissioning, fall haul-out, winterization, gear lube service, propeller service, and any time paint bubbling, white powdering, or corrosion appears 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 more exposed to corrosion.\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 kit. 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 reduce protection.\u003c\/p\u003e\n\u003cp\u003eDo not paint anodes. Antifouling paint, primer, clear coat, or other coatings over the anode surface prevent the water from contacting the sacrificial metal. Tighten all hardware securely and inspect bonding continuity where applicable.\u003c\/p\u003e\n\u003cp\u003eAfter installation, recheck the anodes once the boat has been back in the water, especially if the vessel is kept in a marina with shore power, nearby steel structures, or known stray-current concerns.\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\u003eALU-A1KA\u003c\/strong\u003e — aluminum anode kit part number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCMALPHAKITA\u003c\/strong\u003e — Martyr \/ Canada Metal aluminum kit reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlpha 1 Kit ALU-A1KA\u003c\/strong\u003e — common listing format\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlpha One Gen I Aluminum Anode Kit\u003c\/strong\u003e — application reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eParts Desk Insight\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe most important check is confirming the drive generation.
