Yamaha - Propeller Shaft - Drivetrain Component - 6K1-45611-10-00

Overview

The Yamaha Propeller Shaft | 6K1-45611-10-00 is what takes everything your engine puts out and turns it into forward motion. When a shaft starts to wear or gets even slightly bent, you’ll feel it right away—vibration, noise, or uneven performance. It’s a critical piece inside the lower unit, and once it’s compromised, it can affect everything around it. If you’re already in there fixing damage, it’s worth doing it right with a solid shaft.

Key Features

• Direct Power Transmission – Transfers engine output straight to the propeller for consistent thrust.

• Precision Machined Shaft – Ensures proper alignment and smooth rotation under load.

• High-Strength Construction – Built to handle torque, impact, and long-term use.

• Balanced Operation – Helps reduce vibration and protect surrounding components.

• Superseded Part Update – Replaced by newer version for continued fit and performance support.
