Remove old rubber, gasket material, salt buildup, corrosion residue, grease, and debris without gouging the sealing faces. Inspect the bell housing, transom assembly, water passage area, exhaust passage area, bellows, clamps, fasteners, and related seals while the drive is apart. Install the gasket in the exact position shown in the Mercury\/MerCruiser service diagram and tighten the assembly using the correct service-manual procedure for the drive model.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAlternate\/Superseded Part Numbers\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e27-8M0204656\u003c\/strong\u003e — current Mercury\/MerCruiser formatted service part number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e8M0204656\u003c\/strong\u003e — current short part number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e27-35982\u003c\/strong\u003e — earlier Mercury\/MerCruiser reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e35982\u003c\/strong\u003e — earlier short part number\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eParts Desk Insight\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eBell housing gaskets should be replaced whenever the sealing joint is disturbed.
