RETAINER 93101-22067

Function and technical context

The 93101-22067 seal is a critical sealing component on Yamaha outboard engines, responsible for preventing water and contaminants from entering the lubrication and transmission areas of the engine. Installed in the propeller shaft sealing system, this part works under conditions of constant humidity, dynamic pressure and temperature changes characteristic of the marine environment. Its deterioration allows the penetration of salt water into internal cavities, causing accelerated corrosion, loss of lubrication and failures in adjacent components that compromise the reliability and safety of navigation.

When to replace this part?

The seals show characteristic wear after prolonged exposure to salt water, manifesting with visible lubricant leaks, water entering the crankcase or accelerated degradation of the engine oil. It is recommended to check the condition of this seal during each seasonal maintenance and replace it preventively every 4-5 seasons of intense use or if signs of humidity are observed in the sealing area. Preventative replacement is the most economical practice, as it avoids costly repairs resulting from internal corrosion and failure of adjacent seals and bearings.
