{"title":"Mercury Marine Outboard Water Pump Upper Repair Kits","description":"\u003cp\u003eThis Mercury\/Quicksilver repair kit delivers industry-leading durability for long-lasting use. Outboard water pumps are simple designs. The pump draws water through the intakes and up into the housing.\u003c\/p\u003e\n\u003cp\u003eThe impeller blades (vanes) touch the liner at lower speeds as the driveshaft turns, but as the engine revs up, the impeller blades bend back away from the housing liner. Typical water pump kits includes the following: bearings where applicable, rubber seals, mechanical water pump seal where applicable, side cover gasket, water pump gasket, snap rings located on water pump shaft, and copper drain washers. The pump sends out water from the top of the housing with a brass tube. This travels up through the engine's power head, ensuring it circulates into the cooling passages of the engine. It's good outboard maintenance practice to check your water pump impeller every season, and replace it every two to three seasons. 300 hours of use or every 3 years whichever comes first! How to tell if a water pump is bad: the outboard motor is overheating, the impeller is living on borrowed time, there is a reduced stream of water from the cooling water outlet. The pump sends out water from the top of the housing with a brass tube. This travels up through the engine's power head, ensuring it circulates into the cooling passages of the engine. The water pump kit comes with all the parts necessary to fix any water pump issues. Do it yourself. You can save a lot of money. Mercury Mariner Water Pump Replacement Cost Estimate.

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.

This is a key feature that facilitates a watertight seal that protects the engine and wiring harness from corrosion.
