646-41637-01 – Knob – Yamaha

646-41637-01 Knob is a genuine Yamaha control knob used on various outboard control and adjustment assemblies. This knob allows secure grip when adjusting or operating engine components.

Knobs are commonly used on choke controls, covers, linkages, and adjustment points. Over time, plastic knobs can crack, fade, or become loose. Therefore, replacing damaged knobs keeps controls easy to operate.

A worn knob can make adjustment difficult, especially when the engine is running or under load. Because of this, replacing broken control parts improves safety and reliability. This Yamaha knob fits many older and mid-range outboard models.

Correct control feel is important during service and operation. This part restores proper grip and correct function to the control assembly.

This part is in good usable condition and suitable for repair, restoration, or workshop service work. It is ideal for replacing missing or damaged knobs on Yamaha outboards.
