Sierra 68375P Arctic Tachometer and Hourmeter, 3 Inch, 0-7000 RPM, Gas Engine

The Sierra 68375P is a 3-inch tachometer and hourmeter combination gauge built for gas-powered marine engines. It reads engine speed across a 0-7000 RPM dial range while simultaneously tracking accumulated engine hours, giving operators a single instrument for monitoring both performance and maintenance intervals. The gauge carries Sierra's Arctic finish, a scratch resistant treatment that helps the dial face and bezel hold up against the scrapes and exposure that come with regular use on a boat.

Construction combines durable plastic and metal components, and the gauge is engineered to withstand harsh marine conditions, including sun, spray, and vibration. As an electromechanical gauge, the 68375P meets or exceeds original equipment part standards, making it suitable both as a factory-style replacement and as a new instrument install. It is part of Sierra's IB/IO instrument set lineup, designed to be installed alongside matching Arctic-series gauges such as 68371P, 68365P, 68383P, 68376P, and 68367P for a consistent look across the dash. This particular gauge includes the tachometer/hourmeter unit itself; no additional mounting hardware or wiring components are bundled.
