93210-64272 – O,Ring – Yamaha

The 93210-64272 Yamaha o-ring is a genuine OEM sealing ring used in various Yamaha outboard applications. This o-ring forms a compression seal between mating parts to prevent water, fuel, or air leaks. It is identified as Yamaha part 93210-64272-00 in official catalogs and is commonly found in intake, carburetor, and gasket assemblies.

O-rings like the 93210-64272 Yamaha o-ring play a critical role in maintaining fluid and air boundaries in engine systems. The rubber material compresses slightly when installed, creating a tight barrier that stops contaminants from entering sensitive areas. Because it is an OEM part, this o-ring matches original specifications and fits correctly without modification.

Over time, o-rings can harden, crack, or lose elasticity. When that happens, seals fail and lead to leaks. Fuel leaks can cause poor starting and running. Air leaks can upset the air-fuel mixture, hurting engine performance. Water ingress can rust metal parts. Replacing a worn o-ring with a correct OEM unit restores reliable sealing and prevents these issues.
