Replace the impeller if you notice cracking, missing blades, or reduced cooling system performance. The fuel filter and thermostat should also be replaced during routine maintenance intervals or if you experience overheating or fuel delivery issues.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: What are the signs that my water pump or cooling system needs service?\u003c\/strong\u003e\u003cbr\u003eA: Common symptoms include weak water stream from the tell-tale outlet, engine overheating, steam from the engine cover, or alarm activation. If you notice reduced water flow or temperature gauge readings above normal, inspect and replace the impeller and associated components immediately to prevent engine damage.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Does this kit include everything I need for a complete lower unit service?\u003c\/strong\u003e\u003cbr\u003eA: This kit provides all major service components including the water pump assembly, impeller, seals, fuel filter, thermostat, anode, and gear oil pump.
