🔧 Product Description

Genuine Mercury Quicksilver Flagship 0-8000 RPM Tachometer - Part Number: 79-825282A1

A genuine used Mercury Quicksilver Flagship analog tachometer with a 0-8000 RPM scale for compatible Mercury, Mariner and MerCruiser petrol ignition systems.

This black-face instrument receives a pulse signal from the outboard charging system or petrol-engine ignition circuit. The rear calibration setting must match the engine's pole or pulse configuration.

🔌 Function

The tachometer counts ignition or charging-system pulses and converts them into engine revolutions per minute. Correct pole or cylinder calibration is required to prevent an RPM reading that is proportionally too high or too low.

⚠️ Common Signs of Failure

• No RPM reading while the engine is running
• Reading is incorrect because the selector setting is wrong
• Needle bounces because the signal or ground connection is unstable
• Gauge operates intermittently as engine speed changes
• Illumination or internal needle movement fails
