Press the seal in squarely and to the correct position for the specific lower gearhousing. If gear oil appears milky or water-contaminated, pressure\/vacuum testing the drive after seal replacement is recommended before returning the boat to service.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAlternate\/Superseded Part Numbers\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e3863090\u003c\/li\u003e\n\u003cli\u003eVolvo Penta 3863090\u003c\/li\u003e\n\u003cli\u003eVP3863090\u003c\/li\u003e\n\u003cli\u003eVOLVO-3863090\u003c\/li\u003e\n\u003cli\u003e3853474\u003c\/li\u003e\n\u003cli\u003e3858303\u003c\/li\u003e\n\u003cli\u003eBRP \/ OMC 3863090\u003c\/li\u003e\n\u003cli\u003eGLM 85900\u003c\/li\u003e\n\u003cli\u003eREC3863090\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eParts Desk Insight\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThis seal is best matched by the lower gearhousing diagram, not by engine size.
