Sierra 57903P Amega Oil Pressure Gauge, 2 Inch Dial, 0-80 PSI

The Sierra 57903P Amega oil pressure gauge is a 2 inch dial instrument that reads oil pressure from 0 to 80 PSI, built for boaters who want a clean, easy-to-read gauge at the helm. The Amega line has been a top-selling black dial design since its debut in 1986, pairing a black dial face with red graduations and white numerals for strong contrast in bright sunlight or low light. A vivid white pointer staff makes the needle position easy to read at a glance, and both U.S. And metric scales are included with ISO symbols where appropriate, so the gauge reads correctly for a wide range of boat owners.

The gauge is built with a scratch resistant curved glass lens set into a black, near-flush bezel for a low-profile, integrated look on the dash. It requires a sender with Sender Code "C" and draws 0.10 to 0.15 amps during operation, with a 1/8 NPT thread connection. The bezel outer diameter measures 2.39 inches, and the gauge fits into standard 2 inch dial cutouts alongside other Sierra Amega instruments for a matched gauge set. Optional add-on eyebrow or square bezels are available separately for a custom dash appearance.
