I’ve seen setups where everything looked good, but worn or damaged ducting caused weak water flow and higher temps. The Yamaha Impeller Duct 6HH-51315-00-00 helps guide water efficiently through the pump so the engine stays properly cooled. It’s one of those parts that quietly does its job, but when it’s off, you’ll notice it.\u003c\/p\u003e\n\u003chr data-start=\"577\" data-end=\"580\"\u003e\n\u003ch2 data-section-id=\"1ma7m6t\" data-start=\"582\" data-end=\"597\"\u003eKey Features\u003c\/h2\u003e\n\u003cp data-start=\"599\" data-end=\"702\"\u003e• \u003cstrong data-start=\"601\" data-end=\"631\"\u003eDirects Cooling Water Flow\u003c\/strong\u003e – Channels water through the pump system for efficient engine cooling.\u003c\/p\u003e\n\u003cp data-start=\"704\" data-end=\"799\"\u003e• \u003cstrong data-start=\"706\" data-end=\"731\"\u003eYamaha Engineered Fit\u003c\/strong\u003e – Designed to align correctly with impeller and housing components.\u003c\/p\u003e\n\u003cp data-start=\"801\" data-end=\"894\"\u003e• \u003cstrong data-start=\"803\" data-end=\"830\"\u003eSmooth Internal Passage\u003c\/strong\u003e – Helps maintain consistent water movement without restriction.\u003c\/p\u003e\n\u003cp data-start=\"896\" data-end=\"995\"\u003e• \u003cstrong data-start=\"898\" data-end=\"929\"\u003eDurable Marine Construction\u003c\/strong\u003e – Built to handle constant water exposure, debris, and vibration.\u003c\/p\u003e\n\u003cp data-start=\"997\" data-end=\"1104\"\u003e• \u003cstrong data-start=\"999\" data-end=\"1027\"\u003eEssential Pump Component\u003c\/strong\u003e – Supports overall cooling system performance when servicing the water pump.\u003c\/p\u003e\n\u003chr data-start=\"1106\" data-end=\"1109\"\u003e\n\u003ch2 data-section-id=\"1qx5o2j\" data-start=\"1111\" data-end=\"1141\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/h2\u003e\n\u003cp data-start=\"1142\" data-end=\"1268\"\u003eThe Yamaha Impeller Duct 6HH-51315-00-00 is designed for Yamaha outboard engines equipped with a lower unit water pump system.\u003c\/p\u003e\n\u003cp data-start=\"1270\" data-end=\"1499\"\u003eIt is commonly used during water pump service or rebuilds where proper water flow routing is critical for maintaining engine temperature.
