Sierra 68394P Water Pressure Kit, Outboard, 2 Inch, 0-40 PSI, Includes Fittings and 20 Feet of Tubing

The Sierra 68394P is a complete outboard water pressure kit built around a 2 inch gauge reading 0-40 PSI, giving boaters a direct way to monitor raw water flow to the engine while underway. Because the kit comes complete with fittings and 20 feet of tubing, it can be installed as a full monitoring solution rather than requiring separate purchases of hose or connectors. The gauge and fittings are constructed of brass and stainless steel for corrosion resistance in a marine environment, and the fittings use NPT thread style for compatibility with standard plumbing connections. This kit is part of the Sierra Eclipse line of gauges, designed to give outboard boat owners a reliable read on cooling system performance so a drop in water pressure can be caught before it leads to overheating. The 2 inch gauge face size makes it suitable for helm panels where a compact, easy-to-read display is needed. With everything needed for installation included in one package, the 68394P simplifies adding or replacing water pressure monitoring on an outboard-powered boat.
