SUZUKI WATER PUMP BODY 17450-94J00

Function and technical context

The water pump body is the structural housing that houses the impeller and the rest of the internal components of the seawater cooling system in Suzuki outboard engines. It is part of the primary cooling circuit, being responsible for containing and channeling the flow of water to the engine block to maintain the working temperature within safe limits. A deteriorated, cracked or internally eroded casing directly compromises pumping capacity: it reduces coolant flow, causes leaks and can lead to severe engine overheating. Its structural integrity is as critical as that of the impeller itself, since without a perfect fit between both components the pump immediately loses efficiency.

When to replace this part?

The most common symptoms that indicate that the water pump body must be replaced are: absence or visible reduction of the cooling water jet through the discharge pilot, sign of high temperature on the panel, or presence of galvanic corrosion residues and friction marks on the inside of the housing when the unit is disassembled. It is recommended that the pump body be inspected each time the impeller is replaced—generally every 300-400 hours of boating or at the beginning of each season—as internal wear may not be visible from the outside. Taking advantage of the disassembly to assess the condition of the casing and replace it preventively avoids unexpected breakdowns at sea and reduces the total cost of the intervention.
