This kit fits drives with serials between 2491586 and 0D469858. Second, check the vertical shaft. If there is a preload pin on the shaft, this kit is NOT compatible.

Additionally, review the Engine \u0026amp; Model Compatibility table. This plug fits most Mercury, MerCruiser, and Mariner units with a 3\/8-16 thread drain hole, but it's crucial to verify your model is listed and that it is not part of the Verado series.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eWhy is a non-magnetic plug recommended?\u003c\/summary\u003e\n  \u003cp\u003eStandard magnetic plugs are designed to attract metallic debris in the gear lube. However, non-magnetic stainless steel plugs like this one offer superior corrosion resistance in saltwater and freshwater environments.

The entire screw should be replaced if the head is stripped, the threads are damaged, or if it shows significant corrosion.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eWhat are signs of a failing drain plug seal?\u003c\/summary\u003e\n  \u003cp\u003eThe most common sign is a \"milky\" or creamy appearance in your gear lube, which indicates water has intruded into the gearcase.
