Out on the water—whether you’re pushing through a long channel or easing across a glass-smooth bay—you rely on that steady flow more than anything else. When the pump is healthy, the engine feels confident, strong, and ready for whatever run you’ve planned. That’s why I lean on Mercury Marine parts like the 99157T2 kit. It brings that same peace of mind every boater chases: the feeling that your motor is protected beneath the surface, quietly doing its job.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eKey Features\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eComplete upper water pump repair kit for restoring dependable cooling performance\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eIncludes pump housing assembly, gaskets, plates, o-rings, impeller, key, face plates, and guide sleeve\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eComes with water tube guide sleeve and gear lube fill and vent screw o-rings\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eMarine-grade composite and rubber components built for long, consistent service life\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDesigned to maintain strong water flow and engine protection under heavy use\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eFits select Mercury and Mariner 8–25 horsepower two-stroke and four-stroke outboards\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCompatible with specific eight and nine-point-nine horsepower four-stroke models\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDesigned for fifteen horsepower Mercury BigFoot four-stroke engines\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eAlso fits select twenty and twenty-five horsepower two-stroke engines\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCommon on small fishing boats, tenders, jon boats, pontoons, and lightweight runabouts\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eWhen your water pump is in top shape, you can feel it.
