895289A01 Quicksilver Oil Pressure Gauge | Genuine Used Part

🔧 Product Description

Genuine Mercury / Quicksilver Flagship Oil Pressure Gauge - Correct Part Number: 79-895289A01

A genuine used black-face Mercury / Quicksilver electrical oil-pressure gauge for petrol marine engines and selected four-stroke outboards.

Sometimes listed as 895289A1, a shortened form that omits the zero in the correct service number 895289A01. This instrument is an oil-pressure gauge rather than a water-temperature gauge. It has a black face, blue and white graduations and a black bezel.
