Yamaha - Gear, Drive - Lower Unit Drive Gear - 6D8-11536-00-00

Overview

Anytime you’re working on a Yamaha lower unit, the drive gear is one of those parts you don’t cut corners on. It’s what takes the engine’s rotation and puts it to work, so when it’s worn, you feel it right away. I’ve seen setups go from rough and noisy to smooth just by replacing a tired drive gear. When everything meshes right, the whole motor just runs cleaner and more predictable out on the water.

Key Features

• Primary Drive Function – Transfers engine rotation through the lower unit for consistent propulsion.
• Precision-Cut Gear Teeth – Ensures smooth meshing with mating gears to reduce noise and vibration.
• High-Strength Construction – Built to handle continuous torque and load without premature failure.
• Exact Fit Engineering – Matches Yamaha specifications for proper alignment and dependable operation.
• Corrosion-Resistant Finish – Helps protect against wear and marine exposure inside the lower unit.

Engine & Boat Compatibility

Designed for Yamaha outboard engines requiring this specific drive gear configuration within the lower unit. Suitable for a range of mid to high horsepower marine applications.

FAQ

Q: What are signs the drive gear is going bad?
A: You may notice whining, grinding, or inconsistent power delivery, especially under load.

Q: Can a worn drive gear damage other components?
A: Yes, if left unchecked, it can wear down mating gears and lead to a more expensive repair.

Q: Do I need to replace other gears at the same time?
A: It’s recommended to inspect all gears. If there’s visible wear, replacing them together helps maintain proper meshing.

Q: Is installation something I can handle myself?
A: It requires experience and proper tools to set clearances and alignment correctly, so many prefer a technician.

Q: How does maintenance affect gear life?
A: Regular gear oil changes and checking for water intrusion go a long way in extending gear life.
