YAMAHA WATER PUMP KIT 6CJ-W0078-00
Description
Function and technical context
The water pump kit constitutes the central component of the cooling circuit in Yamaha four-stroke engines. This pump drives the flow of seawater through the internal passages of the engine block, dissipating the heat generated by combustion and ensuring that the propeller maintains optimal operating temperatures. Its correct performance is critical to prevent overheating, which can cause cylinder head deformation, seizure of internal components and severe loss of power in navigation.
When to replace this part?
The wear of the water pump is manifested by a gradual decrease in flow, water leaks in the sealing area of the shaft, and an abnormal increase in engine temperature even when sailing at moderate speed. It is recommended to check the condition of the impeller and seals every boating season or every 300-400 hours of operation, especially in waters with high particulate content or high salinity. Preventively replacing this component prevents serious breakdowns at sea and significantly prolongs the useful life of the engine.
