Impeller Kit - Volvo Penta (21951346)

The water pump is a crucial part of the cooling system in your boat. Coolant is extracted from the radiator and circulated throughout the engine. Coolant circulates through your engine, drawing heat away from engine parts and keeping them cool. The radiator fan and outside air assists cool the coolant as it returns to the radiator before being routed back through the engine. When the boat’s engine is on, it burns the gas and generates heat inside the cylinders. The raw water (lake or outside water) is sent inside the engine block over the power & cylinder heads, absorbing that heat to cool it. With a faulty impeller, pumping water is not possible inside. If your boat impeller goes bad, it will not pump the water inside the engine over the cylinder heads to cool the engine, and it overheats the engine.
