Yamaha - Propeller Shaft - Lower Unit Power Transfer - 6EE-G5611-00-00

Overview

You can usually feel a bad prop shaft before you even see it—vibration, noise, or just not pushing like it should. I’ve pulled lower units apart where a slightly bent shaft caused way more problems than expected. This is the part that takes all that engine power and sends it straight to the prop. When it’s true and in good shape, everything runs smooth and balanced out on the water.

Key Features

• Direct Power Transfer Design – Delivers engine torque efficiently to the propeller.
• Precision Machined Shaft – Ensures proper alignment and smooth rotation within the lower unit.
• Heavy-Duty Metal Construction – Built to handle load, impact, and continuous use.
• Stable Propeller Mounting – Provides secure support for consistent prop performance.
• Exact Yamaha Fitment – Matches factory specifications for proper installation and operation.

Engine & Boat Compatibility

Designed for Yamaha outboard lower units requiring a propeller shaft within the gearcase assembly. Commonly used across small to mid-range Yamaha outboards in recreational and utility boats. Suitable for freshwater and saltwater environments where reliable propulsion and durability are essential.
