Sierra 63474P Sterling 3 Inch Tachometer/Hourmeter, 0-7000 RPM, for 4-Stroke Gas Engines

The Sierra 63474P is a Sterling series 3 inch electric tachometer/hourmeter built for 4-stroke gas engines. It combines RPM monitoring across a 0-7000 RPM range with a built-in hourmeter in a single 3 inch gauge, giving boat owners engine speed and accumulated running time in one compact display without needing separate instruments. The 3 inch face size matches the standard Sterling gauge family, making it straightforward to fit into an existing 3 inch gauge panel cutout alongside other Sterling instruments. Construction is metal, built to hold up to the vibration, heat, and moisture typical of an engine compartment and helm environment. As part of Sierra's Sterling gauge lineup, the 63474P is designed to give an accurate, easy-to-read RPM reading so operators can keep engine speed within a safe operating range and track hours for maintenance scheduling such as oil changes and service intervals. Sierra backs the 63474P with its customer satisfaction warranty, covering the product against defects in workmanship and materials for the useful life of the product. This gauge is intended for 4-stroke gas engine applications and reads 0 to 7000 RPM, making it suited to a wide range of outboard and sterndrive gas engine setups that require a 3 inch tachometer/hourmeter combination gauge.
