Overview

The Yamaha Propeller Shaft | 6J8-45611-00-00 is one of those core parts that takes everything your engine produces and turns it into actual movement in the water. When this shaft is even slightly bent or worn, you’ll feel it right away through vibration or uneven performance. It sits at the heart of the lower unit, handling constant load every time you throttle up. If you’re dealing with damage from impact or wear over time, replacing it is key to getting your motor running smooth again.
