Yamaha - Propeller Shaft - Lower Unit Drivetrain Component - 60V-45611-00-00

Overview

The propeller shaft is one of those parts that takes everything your engine can give and sends it straight to the water. It’s under constant load, especially when you’re running hard or carrying weight. When it’s true and in good shape, the boat runs smooth and steady. But once it’s even slightly off, you’ll feel vibration or notice performance issues pretty quickly.

Key Features

• High-Strength Steel Construction – Built to handle continuous torque and heavy load conditions.
• Precision Machined Splines – Ensures secure propeller fitment and efficient power transfer.
• True Running Alignment – Helps minimize vibration and maintain smooth operation at speed.
• OEM Fitment Accuracy – Matches Yamaha specifications for proper installation and performance.
