SUZUKI SEAL GASKET 11433-87J00

Function and technical context

This retaining gasket acts as a sealing element in the engine block, preventing fluid leakage between joining surfaces subjected to movement or pressure. It is part of the structural sealing system of the outboard propeller, working in areas where the integrity of the closure is decisive for the correct functioning of the assembly. A seal in poor condition can cause oil or coolant leaks, cross contamination between circuits and progressive damage to internal engine components. Its correct installation guarantees the tightness of the system and prevents major breakdowns in the DF40 and DF50 groups.

When to replace this part?

The most common symptoms of a deteriorated seal are oil stains in the bilge or on the underside of the engine, a burning smell from oil in contact with hot surfaces, and abnormal lubricant consumption without apparent cause. It is recommended to inspect the condition of the seals and sealing gaskets at each seasonal inspection, especially after many hours of navigation or after prolonged storage out of the water. Replacing the seal preventively when detecting the first signs of leakage avoids costly repairs and unexpected immobilization of the boat.
