Yamaha - Propeller Shaft - Lower Unit Drivetrain - 6E0-45611-01-00

Overview

The prop shaft is one of those parts you don’t think about until something feels off at the back of the boat. It’s taking all the engine’s power and sending it straight to the prop, so even a small issue shows up quickly. I’ve seen bent or worn shafts cause vibration that just won’t go away no matter what you try. Replacing it gets everything spinning true again and brings back that smooth, solid feel on the water.

Key Features

• Direct Power Transfer – Delivers engine output efficiently to the propeller for consistent performance.
• Hardened Steel Construction – Built to handle torque, load, and constant rotation under pressure.
• Precision Machined Fit – Ensures proper alignment within the lower unit for smooth operation.
• OEM Replacement Design – Matches original specifications for dependable installation and function.

Engine & Boat Compatibility

Designed for Yamaha 2-stroke outboard engines with standard lower unit gearcases. Commonly used on smaller to mid-range horsepower motors found on skiffs, jon boats, and fishing boats.
