Yamaha - Driven Gear - Lower Unit Component - 62Y-11537-10-00

Overview

Inside the lower unit, the driven gear is what takes the load and keeps everything moving the way it should. When it starts wearing down, you’ll notice it—noise, vibration, or just not transferring power smoothly. I’ve replaced these in setups where the motor felt rough under load, and it made a big difference right away. When this gear is solid, the whole drivetrain feels tighter and more dependable.
