🔧 Product Description

Genuine Mercury MerCruiser Water Temperature Gauge - Part Number: 46797A1

A genuine used Mercury / MerCruiser engine-temperature gauge for selected early petrol sterndrive and inboard instrument panels.

The gauge receives a variable-resistance signal from the engine-mounted temperature sender and displays the cooling-system temperature. The replacement gauge and sender must use the same resistance calibration.

⚙️ Key Features

  • Genuine used Mercury / MerCruiser temperature gauge
  • Original OEM part number 46797A1
  • Early Quicksilver / MerCruiser instrument design
  • Electrical sender-operated gauge
  • Suitable for selected pre-1985 dashboards

🚤 Compatibility

Commonly used on

  • Early Mercury and MerCruiser sterndrive dashboards
  • Kiekhaefer and Quicksilver petrol-engine instrument panels
  • GM-based marine petrol engines using the matching sender

Typically suits

  • Early MerCruiser inline-four, inline-six, V6 and V8 petrol packages
  • Pre-1985 instrument systems where 46797A1 or a listed related reference is specified
  • 12-volt marine electrical systems
  • Fitment controlled by sender calibration and instrument-panel design

🔌 Function

The gauge converts the temperature sender's resistance into a needle position showing approximate engine temperature.

  • Gauge remains cold
  • Needle immediately moves to maximum
  • Reading is inaccurate
  • Gauge reacts when the wiring moves
  • Sender and gauge do not match
  • Illumination does not operate
