A grooved, rusted, pitted, or worn driveshaft can damage the new seal and cause repeat water intrusion. During service, inspect the paired driveshaft seal, water pump base, shift shaft seal, propeller shaft seals, drain and vent screw gaskets, and the seal bore condition. Press the seal squarely into the bore using the correct service procedure and verify the gearcase with a pressure\/vacuum test before refilling with gear lubricant.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAlternate\/Superseded Part Numbers\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e26-43036\u003c\/strong\u003e — Mercury\/MerCruiser formatted part number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e43036\u003c\/strong\u003e — Manufacturer part number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e26-43035\u003c\/strong\u003e — related upper driveshaft oil seal commonly serviced with this seal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e26-43035A4\u003c\/strong\u003e — related lower-unit gear housing seal kit reference; verify by gearcase diagram\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSierra 18-0522\u003c\/strong\u003e — aftermarket cross-reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGLM 85170 \/ 85160\u003c\/strong\u003e — aftermarket cross-reference references\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSEI 94-205-11\u003c\/strong\u003e — aftermarket cross-reference reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eParts Desk Insight\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eDriveshaft seals are part of a complete gearcase sealing system, so water in the gear oil should not be diagnosed by replacing only one seal unless the leak point has been confirmed.
