Yamaha - Gearbox Bung Washer (90430-08003)

Beyond its fit, this washer acts as a robust barrier, guarding against potential leaks and ensuring the seamless function of the gearbox. It's not just about fitting but fitting right, and our washer does just that, every time.

However, even the best parts require regular maintenance. To maintain peak performance and the health of your Yamaha outboard's gearbox, it's recommended to replace the 90430-08003 bung washer annually. This regular replacement ensures that your gearbox remains sealed, secure, and functioning at its best year after year.
