Sierra 68369P Water Pressure Kit, Outboard, 2 Inch Gauge, 0-40 PSI

The Sierra 68369P is a 2 inch outboard water pressure gauge kit with a 0-40 PSI dial range, built to give boaters a clear, reliable readout of engine water pressure at a glance. The kit uses sender code R and comes complete with fittings and 20 feet of tubing, so it is ready to plumb into an outboard cooling system without sourcing extra hardware separately.

The gauge itself features a white bezel with black on white graphics for strong contrast and readability, and both through-dial and perimeter lighting so the dial stays legible at night. The face carries U.S. And metric scales with ISO symbols where appropriate, making it easy to read for a range of boaters. The lens is domed glass, which sheds water and resists scratching, holding up to the conditions found on the water. The instrument has a 1/2 inch NPT thread connection.

This kit is designed for outboard installations and is intended to be added to a helm or dash layout alongside other engine instrumentation. Everything needed for the pressure-sensing side of the installation, the gauge, fittings, and 20 feet of tubing, is included in the box under part number 68369P.
