Yamaha - Dog Clutch - Lower Unit Shifting Component - 6CE-45631-00-00

Overview

When a Yamaha doesn’t shift clean into gear, the dog clutch is usually one of the first things I check. It’s what locks the gears in when you go into forward or reverse, so it takes a lot of abuse over time. I’ve seen worn clutches cause slipping or that harsh grinding sound nobody wants to hear. When it’s in good shape, shifting feels solid and immediate, just like it should.
