The sea water pump cover encloses the impeller housing on the raw water cooling pump, maintaining proper water flow and pressure through the cooling circuit. A cracked, worn, or corroded pump cover can cause coolant leaks, loss of cooling efficiency, and engine overheating. This kit contains the cover and associated hardware needed to complete the repair. This is an authentic factory original part — never installed, never used.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"auto\"\u003e\u003cstrong\u003eCondition Details:\u003c\/strong\u003e This is a New Old Stock (NOS) part.
