💡 What causes seawater pump impeller wear on Yanmar 2YM marine diesel engines?
The main issue is usually material fatigue after years of pumping abrasive saltwater through tight clearances. Your handy replacement kit gives you the correct geometry to restore strong coolant flow fast.
- The rubber compound resists abrasion that eats away thin blades over time
- Proper shaft alignment prevents rubbing heat that melts plastic stems during runs
- Correct blade pitch ensures your cooling system moves enough water to stop overheating
