That is why having a dependable, factory-built sea pump gives such a sense of calm. The Mercury 8M0139996 Sea Pump Kit delivers that quiet reassurance every boater wants, especially when you are running through choppy inlets or easing away from a crowded marina with the sun dropping behind you. Designed for MerCruiser MPI engines equipped with an air-actuated drain system, this pump keeps coolant flowing steady and strong so the engine stays relaxed, responsive, and protected. It is the kind of part that earns trust mile after mile.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eKey Features\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eFully assembled sea pump designed for select MerCruiser MPI engines\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eMarine-grade construction for corrosion resistance in harsh saltwater use\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEngineered to meet or exceed Mercury Marine OEM specifications\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eBuilt for consistent cooling flow and long service life\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eIdeal replacement to restore proper engine cooling performance\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDesigned to handle abrasive conditions common in coastal boating\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDrop-in design for straightforward installation\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eFits MerCruiser 4.3L, 5.0L, 5.7L, 6.2L, and 8.2L MPI engines with air-actuated drain systems\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eNot compatible with MerCruiser 6.2L MPI engines serial number 2A456613 and higher\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eSuitable for sport boats, cruisers, runabouts, and inboard tow boats\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eWorks in both saltwater and freshwater environments\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDesigned for inboard and sterndrive cooling systems requiring a sea pump assembly\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e A cooling pump has one job, but it is a job your whole day depends on.
