Yamaha - Propeller Shaft - Lower Unit Drivetrain Component - 63D-45611-00-00

Overview

The propeller shaft is what takes all the power from the lower unit and delivers it straight to the prop. When this shaft starts to wear, bend, or get damaged, you’ll feel it right away—vibration, noise, or poor performance under load. This Yamaha propeller shaft is built to handle that load and keep power transfer smooth and reliable. It’s a critical drivetrain component that keeps everything running solid when you’re out on the water.
