Yamaha - Dog Clutch - Lower Unit Shifting Component - 60V-45631-00-00

Overview

If shifting starts feeling rough or the motor won’t stay in gear, this is usually one of the first parts I look at. The dog clutch is what actually locks the gears together when you shift, so it takes a hit every single time you go in and out of gear. When it’s fresh, shifts feel solid and clean. When it’s worn down, you’ll feel slipping or hear grinding, especially under load.

Key Features

• Positive Gear Engagement – Locks gears securely for reliable forward and reverse operation.
• Hardened Steel Construction – Built to handle repeated shifting impact without rounding off edges.
• Precision Machined Contact Surfaces – Ensures clean engagement and smoother shifting feel.
• OEM Fitment Accuracy – Matches Yamaha specifications for proper alignment inside the lower unit.
