Always confirm compatibility using the Mercury or MerCruiser serial number before ordering, especially where older \u003cstrong\u003e27-43033\u003c\/strong\u003e has been replaced by \u003cstrong\u003e27-430331\u003c\/strong\u003e.\u003c\/p\u003e\n\u003ch2\u003eWhen This Part Needs Replacement\u003c\/h2\u003e\n\u003cp\u003eReplace this gasket whenever the water pump cover, face plate, or impeller assembly is serviced. A compressed, torn, hardened, or misaligned gasket can cause poor sealing, reduced pump efficiency, water leakage inside the pump stack, or repeat lower-unit service.\u003c\/p\u003e\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eClean the water pump cover and face plate surfaces before installation. Remove all old gasket material without scratching the mating surfaces, inspect the face plate and water pump housing for scoring, and install the gasket in the correct orientation. For best results, replace related water pump wear parts at the same time if they show grooves, corrosion, or heat damage.\u003c\/p\u003e\n\u003ch2\u003eAlternate \/ Superseded Part Numbers\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e27-43033\u003c\/li\u003e\n\u003cli\u003e43033\u003c\/li\u003e\n\u003cli\u003e27-430331\u003c\/li\u003e\n\u003cli\u003e430331\u003c\/li\u003e\n\u003cli\u003e27-43033-1\u003c\/li\u003e\n\u003cli\u003eSierra 18-2564 — related aftermarket interchange reference\u003c\/li\u003e\n\u003cli\u003eAM27-430331 — related aftermarket interchange reference\u003c\/li\u003e\n\u003cli\u003eHonda 19234-ZW1-003 — related interchange reference\u003c\/li\u003e\n\u003cli\u003eOMC \/ Johnson \/ Evinrude 0509257 — related interchange reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eParts Desk Insight\u003c\/h2\u003e\n\u003cp\u003eThis gasket is commonly ordered during impeller service, but the important detail is matching the complete water pump stack by serial number.
