About this part
Genuine Yamaha 6H14389H1000 (O-ring) — an OEM replacement part built to Yamaha standards. OEM specification helps avoid common fitment issues and supports long-term reliability on the water.
Why choose genuine Yamaha?
Choosing genuine Yamaha OEM helps avoid problems often seen with pattern parts: mis-sized sealing profiles, inconsistent rubber compounds, poor plating, and connectors that don’t lock correctly. On a marine engine, those small differences can become big issues.
Notes for this part
Gaskets and seals prevent leaks and help systems hold pressure where required. OEM materials and profiles matter — particularly for cooling and gearcase components where correct sealing is critical.
Installation tip: follow correct torque values and sequences, avoid over-tightening, and replace any fasteners that are corroded or stretched.
Warranty
New genuine parts include a 1-year warranty (correct application and installation required).
Ordering tips
Ordering tip: Yamaha variations can exist within the same year. The safest approach is to confirm the part number against your exact model code / serial range before purchase.
