🔧 Product Description

Genuine Mercury MerCruiser Oil Pressure Gauge - Part Number: 59056A1

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

The gauge receives a variable-resistance signal from the engine-mounted oil-pressure sender and displays lubrication pressure. It belongs to the early Quicksilver square-face instrument family.

⚙️ Key Features

  • Genuine used Mercury / MerCruiser oil-pressure gauge
  • Correct OEM part number 59056A1
  • Early Quicksilver instrument-panel design
  • Electrical sender-operated gauge
  • Common marine oil-pressure display of approximately 0-80 PSI

🚤 Compatibility

Commonly used on

  • Early MerCruiser sterndrive dashboards
  • Quicksilver inboard and sterndrive instrument panels
  • Petrol engines with a compatible resistance-type pressure sender

Typically suits

  • Pre-1985 MerCruiser inline-four, inline-six, V6 and V8 petrol engines
