Water Pump Gasket 17472-93911

Function and technical context

This gasket acts as a sealing element in the seawater cooling pump housing of the water cooling system, ensuring that the cooling circuit remains sealed and leak-free between the pump body surfaces. It works directly in the cooling system of the outboard motor, where the pump forces water through the engine block to dissipate heat generated during combustion. A worn gasket allows air to enter the circuit or loss of flow rate, which compromises the engine's cooling capacity and can lead to severe overheating of the assembly. Its correct condition is essential to maintain working pressure and continuous circulation of cooling water, especially in motors with intensive use or in warm waters. This part number is compatible with Suzuki outboard motors of the DF and DT series, as well as with Johnson and Evinrude equipment, with part number 5035603 being the current designation that replaces the previous 5033115 in the OMC/BRP catalog.

When to replace this gasket?

The most common symptoms indicating deterioration of this gasket are the presence of moisture or traces of water in the cooling pump area, the reduction or absence of the cooling water jet from the discharge indicator (the well-known "tell-tale stream"), and an abnormal increase in engine temperature detected on the thermal warning light. It is recommended to inspect and replace this gasket in every intervention on the water pump, typically every two seasons or when replacing the cooling impeller. Replacing this gasket preventively during scheduled maintenance avoids overheating failures during navigation and extends the service life of the pump assembly.
