Yamaha - Dog Clutch - Lower Unit Gear Component - 62Y-45631-00-00

Overview

If your outboard is slipping in and out of gear or not engaging cleanly, the dog clutch is usually where the problem starts. It’s the piece that actually locks the gears together when you shift, so when it’s worn, you’ll feel it right away. I’ve seen plenty of lower units torn down where this part was rounded off from years of use. Replacing it brings back that solid, confident shift you expect from a Yamaha.

Key Features

• Genuine Yamaha Fitment – Built to exact specifications for proper gear alignment.
• Hardened Metal Construction – Designed to handle repeated shifting and high torque loads.
