Yamaha - Driven Gear - Engine Power Transmission Component - 63P-11537-00-00

Overview

The driven gear works hand-in-hand with the drive gear, and if one’s off, you’ll feel it in the engine. I’ve torn down motors where uneven wear here caused noise and rough operation that only got worse over time. This gear takes incoming motion and keeps everything turning in sync inside the engine. When it’s in good condition, the whole system runs smoother and more efficiently.

Key Features

• Precision Gear Engagement – Works with the drive gear for smooth power transfer.
• OEM Fitment – Designed to Yamaha specifications for proper alignment and function.
• High-Strength Construction – Built to handle continuous internal engine load.
• Consistent Mechanical Operation – Supports stable timing and internal movement.

Engine & Boat Compatibility

Fits Yamaha outboard engines with compatible internal gear systems. Commonly used across mid-range horsepower outboards on center consoles, bay boats, and recreational vessels.

FAQ

Q: What are signs this driven gear is worn?
A: Grinding sounds, vibration, or inconsistent engine performance are common indicators.
