6y5-83540 Knots/KPH Yamaha Speedometer | Genuine Used Part

🔧 Product Description

Yamaha 6Y5 Pro Series Tachometer - Incomplete Part Number: 6Y5-83540

The listing number 6Y5-83540 identifies a Yamaha tachometer part-number family, not a knots/KPH speedometer.

A complete Yamaha number requires a suffix such as 6Y5-83540-05-00, 6Y5-83540-14-00, 6Y5-83540-15-00 or another application-specific version. The exact suffix, face markings, warning lamps and rear connector must be confirmed from the label on the gauge before compatibility is assigned.

⚙️ Key Features

• Base family number 6Y5-83540
• Tachometer / engine-RPM gauge family
• Exact RPM range and warning functions depend on the suffix
• May include two-stroke oil indicators on some versions
• May be a plain tachometer without oil indicators on other versions
