Yamaha - Gear - Engine Power Transmission Component - 60S-G5560-00-00

Overview

Internal gears don’t get much attention until something goes wrong, but they’re doing constant work every time the engine’s running. I’ve seen engines develop noise or lose efficiency just from worn gear teeth that couldn’t mesh properly anymore. This gear plays a role in keeping power moving smoothly through the system. When it’s in good shape, everything runs quieter and more consistent.

Key Features

• Precision Gear Engagement – Ensures smooth transfer of power between internal components.
• OEM Fitment – Built to Yamaha specifications for accurate alignment and operation.
• High-Strength Construction – Designed to handle continuous engine load and stress.
• Reliable Operation – Supports consistent mechanical timing and performance.

Engine & Boat Compatibility

Fits Yamaha outboard engines with compatible internal gear systems. Commonly used across various Yamaha outboard models and horsepower ranges.

FAQ

Q: What are signs this gear is worn out?
A: Grinding noise, vibration, or reduced engine smoothness can indicate wear.

Q: Can a worn gear affect overall engine performance?
A: Yes, it can lead to inefficient power transfer and additional internal wear.

Q: Should gears be replaced during major service?
A: If there’s visible wear or damage, it’s best to replace them.

Q: Does lubrication impact gear lifespan?
A: Proper lubrication is critical to reducing friction and extending gear life.

Q: Is installation difficult?
