Yamaha - Driven Gear - Engine Gear Train Component - 6EK-11537-00-00

Overview

Once you’re inside the engine and dealing with gears, you realize how much everything depends on clean, precise movement. I’ve seen worn driven gears cause noise and uneven operation that only gets worse if it’s left alone. This gear plays a key role in keeping internal rotation steady and timed right. When it’s in good shape, the engine runs smooth, quiet, and consistent under load.

Key Features

• Precision Gear Tooth Design – Ensures smooth engagement with mating gears for reliable operation.
• Consistent Internal Rotation – Helps maintain steady movement within the engine gear train.
• Hardened Metal Construction – Built to withstand friction, load, and continuous engine use.
• Reduced Wear Performance – Designed for clean meshing to minimize stress on surrounding components.
• Exact Yamaha Fitment – Matches factory specifications for proper alignment and installation.

Engine & Boat Compatibility

Designed for Yamaha outboard engines utilizing internal gear train systems within the powerhead. Commonly used across mid-range Yamaha outboards in both recreational and commercial marine applications. Suitable for freshwater and saltwater environments where reliable engine operation is essential.
