A grooved shaft, corroded seal bore, damaged carrier, or worn water pump base can cause repeat leakage even with new seals installed. After assembly, pressure\/vacuum test the gearcase before refilling with gear lubricant and returning the lower unit to service.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAlternate\/Superseded Part Numbers\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e26-43035A4\u003c\/strong\u003e — Mercury\/MerCruiser formatted kit number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e43035A4\u003c\/strong\u003e — Manufacturer part number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e26-43035\u003c\/strong\u003e — related individual upper driveshaft oil seal reference; verify by diagram before substituting individual components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eParts Desk Insight\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eA complete gear housing seal kit is usually the better choice when the lower unit has water-contaminated oil or fails a pressure\/vacuum test.
