| 1. Its primary function is to circulate water through the engine's cooling system, which is essential for maintaining the engine's optimal operating temperature and preventing overheating. |
| 2. As the impeller spins within the water pump housing, it draws water from the lake, river, or ocean and forces it through the engine's cooling passages. |
| 3. This continuous flow of water absorbs and dissipates heat generated by the engine, ensuring reliable and efficient operation. |
| 1. High-Performance Design: The impeller is designed with multiple blades that efficiently draw water into the cooling system, ensuring a consistent and strong water flow at various engine speeds. |
| 2. Corrosion-Resistant Materials: The rubber and any metal components are selected for their resistance to corrosion, making the impeller suitable for use in both freshwater and saltwater environments. |
| 3. Precision Fit: Engineered to fit perfectly within the pump housing of specific Yamaha outboard models, ensuring optimal performance and preventing leaks. |
| 4. Flexible Blades: The impeller blades are flexible, allowing them to bend and conform under pressure, which helps to maintain a tight seal and effective water pumping action. |
| 1. Regular Inspection: Routinely inspect the impeller, especially before the boating season or after prolonged use, to check for signs of wear, cracks, or missing blades. |
| 2. Replace Annually or as Needed: It is generally recommended to replace the impeller annually or every 100 hours of operation, whichever comes first, especially if the motor is frequently used in shallow, sandy, or debris-filled waters. |
| 3. Proper Installation: When installing a new impeller, ensure it is correctly positioned within the pump housing, with the blades oriented in the correct direction to match the engine's rotation. |
| 4. Lubricate During Installation: Apply a small amount of water-resistant grease to the impeller blades before installation to ease the initial start-up and prevent dry friction, which can cause damage. |
| 5. Flush After Each Use: Flush the cooling system with fresh water after each use, especially if operating in saltwater, to remove debris, sand, and salt deposits that can damage the impeller. |
| 6. Check Pump Housing: Inspect the pump housing for signs of wear or damage. A worn or damaged housing can affect impeller performance and should be replaced if necessary. |
| 1. Overheating Engine: One of the most obvious signs of impeller failure is engine overheating, which occurs when water is not circulating properly. |
| 2. Reduced Water Flow from Cooling System Indicator (Tell-Tale): A weak or nonexistent tell-tale stream is a strong indicator that the impeller may be worn or damaged. |
| 3. Unusual Engine Noise: A damaged impeller can cause unusual noises from the water pump due to broken or misaligned blades. |
