Sierra Amega 68357P Outboard Water Pressure Gauge Kit, 2 Inch, 40 PSI, WP Sender

The Sierra Amega 68357P is a 2 inch outboard water pressure gauge kit that reads from 0 to 40 PSI, giving boaters a direct reading of engine cooling water pressure at the helm. The gauge features a black dial with red graduations, white numerals, and a white pointer staff for clear visibility at a glance, set behind a scratch resistant curved glass lens in a black near-flush bezel that fits standard 2 inch dashboard cutouts. It draws only 0.10 to 0.15 amps, keeping electrical load low on outboard charging systems.

As a complete kit, the 68357P includes the fittings and 20 feet of tubing needed to plumb the gauge to the engine's water pressure sender using the "WP" sender code, so no additional sending unit needs to be sourced separately. It is designed for outboard installations. Yamaha outboards require a separate adapter (P/N 61886P) to complete the installation; other outboard installations do not require this adapter. Optional add-on eyebrow or square bezels are available separately for boaters who want a different dash finish.
