Yamaha - Idler Gear - Starter Drive Component - 60V-8183T-00-00

Overview

This is one of those parts you don’t think about until the engine doesn’t crank like it should. The idler gear plays a role in transferring motion from the starter to the engine, so it needs to engage clean every time you hit the key. When it’s worn, you’ll hear it—grinding or slipping during startup. It’s a small piece, but it’s critical for reliable starts, especially when you’re out on the water and need the motor to fire up without hesitation.

• Hardened Gear Teeth – Built to handle repeated engagement without premature wear.
