Sierra 59705P Sahara Electric Oil Pressure Gauge, 2 Inch, 0-80 PSI, Inboard/Outboard

The Sierra 59705P is a Sahara series electric oil pressure gauge built for inboard and inboard/outboard (IB/IO) engine dashboards. It reads a 0 to 80 PSI range on a 2 inch dial, giving boaters a direct, at-a-glance check of engine oil pressure while underway. The Sahara design features a tan dial and retainer with black graduations and numerals, paired with a black pointer tipped in fire-orange for quick visibility from the helm. Lighting is combined red through-dial and white perimeter illumination, so the gauge stays readable at night without washing out the dial face.

The gauge face is protected by a scratch resistant curved glass lens set into a black matte, near-flush bezel, giving the gauge a clean, low-profile fit against the dash. The 59705P is part of Sierra's Sahara instrument family for IB/IO applications and is designed to install alongside matching Sahara gauges such as tachometer and hour meter units for a coordinated dash set. As an electric gauge, it is intended for use with a compatible sending unit and wiring rather than a direct mechanical line connection.
