Genuine Yamaha 6G511181A200 (Gasket, cylinder head 1) — 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?
For marine use, OEM specification matters. Yamaha components are designed for salt, humidity, temperature swings, and continuous vibration. If you’re aiming for “fit once, do it right”, genuine parts are typically the safest option.
Notes for this part
Installation tip: follow correct torque values and sequences, avoid over-tightening, and replace any fasteners that are corroded or stretched.
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.
Warranty
1-year warranty applies to new parts (terms apply; damage from incorrect installation isn’t covered).
Ordering tips
Ordering tip: when buying multiple items, it’s worth reviewing the same diagram section for related gaskets and seals so everything arrives together.
