A worn or corroded shift shaft can damage the new seal and cause repeat leakage. During gearcase service, also inspect the driveshaft seals, propeller shaft seals, drain and vent screw gaskets, water pump base, and pressure\/vacuum test results before returning the lower unit to service. Follow the Mercury service manual for the correct installation procedure and fastener torque for the specific gearcase.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAlternate\/Superseded Part Numbers\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e23-43052A4\u003c\/strong\u003e — Mercury\/MerCruiser formatted part number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e43052A4\u003c\/strong\u003e — Manufacturer part number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e23-43052A1\u003c\/strong\u003e — earlier kit reference to verify by serial number and diagram\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e23-43052A2\u003c\/strong\u003e — earlier kit reference to verify by serial number and diagram\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e23-43052A3\u003c\/strong\u003e — earlier kit reference to verify by serial number and diagram\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSierra 18-2358\u003c\/strong\u003e — aftermarket cross-reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGLM 21024\u003c\/strong\u003e — aftermarket cross-reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMallory 9-76139\u003c\/strong\u003e — aftermarket cross-reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSEI 98-205-05K\u003c\/strong\u003e — aftermarket cross-reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eParts Desk Insight\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe shift shaft bushing area is one of the common gearcase leak points because it sits above the gear housing and seals a moving shaft.
