Yamaha – Lower Unit Assembly | Drivetrain Component | 60V-45300-00-8D

Overview

When a lower unit starts going, you feel it right away—noise, vibration, or just not transferring power like it should. I’ve swapped a lot of these on Yamaha 60V setups, and it’s one of those repairs that completely changes how the boat runs. Everything from shifting to throttle response tightens back up. Once it’s in place, the motor feels solid again and ready to work.
