I’ve seen fresh impellers installed into worn housings, and the cooling performance still wasn’t right. The Yamaha Impeller Housing 6R7-51312-03-00 gives the impeller the proper surface and clearance to move water efficiently. If the housing is worn, the whole cooling system suffers, so it’s worth getting it right.\u003c\/p\u003e\n\u003chr data-start=\"551\" data-end=\"554\"\u003e\n\u003ch2 data-section-id=\"1ma7m6t\" data-start=\"556\" data-end=\"571\"\u003eKey Features\u003c\/h2\u003e\n\u003cp data-start=\"573\" data-end=\"702\"\u003e• \u003cstrong data-start=\"575\" data-end=\"607\"\u003eOptimized Water Pump Chamber\u003c\/strong\u003e – Provides the correct internal shape for efficient water movement through the cooling system.\u003c\/p\u003e\n\u003cp data-start=\"704\" data-end=\"818\"\u003e• \u003cstrong data-start=\"706\" data-end=\"731\"\u003eYamaha Engineered Fit\u003c\/strong\u003e – Designed to match original specifications for proper alignment with pump components.\u003c\/p\u003e\n\u003cp data-start=\"820\" data-end=\"928\"\u003e• \u003cstrong data-start=\"822\" data-end=\"857\"\u003eWear-Resistant Interior Surface\u003c\/strong\u003e – Built to handle constant impeller contact without excessive scoring.\u003c\/p\u003e\n\u003cp data-start=\"930\" data-end=\"1041\"\u003e• \u003cstrong data-start=\"932\" data-end=\"975\"\u003eSupports Consistent Cooling Performance\u003c\/strong\u003e – Helps maintain steady water flow to protect engine temperature.\u003c\/p\u003e\n\u003cp data-start=\"1043\" data-end=\"1150\"\u003e• \u003cstrong data-start=\"1045\" data-end=\"1074\"\u003eDirect Replacement Design\u003c\/strong\u003e – Fits in place of the original housing during standard water pump service.\u003c\/p\u003e\n\u003chr data-start=\"1152\" data-end=\"1155\"\u003e\n\u003ch2 data-section-id=\"1qx5o2j\" data-start=\"1157\" data-end=\"1187\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/h2\u003e\n\u003cp data-start=\"1188\" data-end=\"1317\"\u003eThe Yamaha Impeller Housing 6R7-51312-03-00 is designed for Yamaha outboard engines equipped with a lower unit water pump system.\u003c\/p\u003e\n\u003cp data-start=\"1319\" data-end=\"1536\"\u003eIt is commonly used during water pump maintenance when replacing worn or damaged housings that can affect cooling efficiency.
