SUZUKI PRESSURE VALVE GASKET

Function and technical context

This gasket acts as a sealing element in the pressure valve of the outboard motor's water cooling system, sealing the passage between components and preventing liquid leaks or pressure losses in the circuit. Its correct operation is crucial to maintaining the integrity of the engine's thermal management system: poor sealing can cause a pressure drop in the water circuit, with the consequent risk of overheating and serious damage to the cylinder head or pistons. The part corresponds to the reference 17616-87J00 in the Suzuki catalog and has the manufacturing reference REC17616-87J00, and is also applicable to OMC engines (ref. 5031426).

When to replace this part?

The most common symptoms of deterioration in a pressure valve gasket include the presence of moisture or traces of water around the valve, loss of pressure in the cooling circuit and the tripping of the high temperature indicator on the instrument panel without an apparent cause in the water pump or thermostat. It is recommended to inspect this gasket during each seasonal maintenance or whenever work is done on the cooling circuit, since the sealing material degrades with thermal cycles and exposure to salt water. Replacing it preventively during a scheduled inspection avoids navigation breakdowns that can compromise the safety of the boat and lead to high-cost repairs.
