0775799 BRP Water Pressure Gauge | Genuine Used Part

🔧 Product Description

Genuine BRP OMC Two-Inch Water Pressure Gauge - Part Number: 0775799

A genuine used BRP mechanical water-pressure gauge for monitoring outboard cooling-system pressure.

The gauge connects to an engine cooling-water passage through a small pressure hose. It provides a direct indication that the water pump and cooling passages are developing pressure while the engine is operating.
