I’ve seen plenty of pumps rebuilt where the old housing was worn or scored, and the new impeller never had a chance to work right. The Yamaha Impeller Housing 6HH-51312-00-00 is what keeps everything sealed and moving water the way it should. If the housing isn’t in good shape, your cooling system won’t perform the way it needs to out on the water.\u003c\/p\u003e\n\u003chr data-start=\"568\" data-end=\"571\"\u003e\n\u003ch2 data-section-id=\"1ma7m6t\" data-start=\"573\" data-end=\"588\"\u003eKey Features\u003c\/h2\u003e\n\u003cp data-start=\"590\" data-end=\"714\"\u003e• \u003cstrong data-start=\"592\" data-end=\"625\"\u003eSupports Efficient Water Flow\u003c\/strong\u003e – Provides the proper chamber for the impeller to move cooling water through the system.\u003c\/p\u003e\n\u003cp data-start=\"716\" data-end=\"836\"\u003e• \u003cstrong data-start=\"718\" data-end=\"743\"\u003eYamaha Engineered Fit\u003c\/strong\u003e – Designed to match factory specifications for correct alignment with water pump components.\u003c\/p\u003e\n\u003cp data-start=\"838\" data-end=\"943\"\u003e• \u003cstrong data-start=\"840\" data-end=\"868\"\u003eDurable Internal Surface\u003c\/strong\u003e – Built to resist wear from constant impeller rotation and water movement.\u003c\/p\u003e\n\u003cp data-start=\"945\" data-end=\"1058\"\u003e• \u003cstrong data-start=\"947\" data-end=\"975\"\u003eMaintains Pump Integrity\u003c\/strong\u003e – Helps ensure consistent cooling performance when paired with a healthy impeller.\u003c\/p\u003e\n\u003cp data-start=\"1060\" data-end=\"1165\"\u003e• \u003cstrong data-start=\"1062\" data-end=\"1094\"\u003eDirect Replacement Component\u003c\/strong\u003e – Installs in place of the original housing during water pump service.\u003c\/p\u003e\n\u003chr data-start=\"1167\" data-end=\"1170\"\u003e\n\u003ch2 data-section-id=\"1qx5o2j\" data-start=\"1172\" data-end=\"1202\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/h2\u003e\n\u003cp data-start=\"1203\" data-end=\"1346\"\u003eThe Yamaha Impeller Housing 6HH-51312-00-00 is designed for Yamaha outboard engines that use a lower unit water pump system for engine cooling.\u003c\/p\u003e\n\u003cp data-start=\"1348\" data-end=\"1560\"\u003eIt is commonly replaced during water pump service when wear or scoring inside the housing can affect cooling efficiency.
