Sierra 63473P Sterling 3 Inch Electric Tachometer for 4-Stroke Gas Engines

The Sierra 63473P is a Sterling series 3 inch electric tachometer built for 4-stroke gas engines. It gives helm-side visibility of engine RPM so operators can monitor engine performance, protect against over-revving, and keep the powertrain running within its safe operating range. As part of Sierra's Sterling gauge line, it is designed to meet or exceed the performance of the original equipment gauge it replaces, and it is built to withstand the harsh marine environment while delivering consistent, accurate readings at the helm.

This tachometer is intended for boats powered by 4-stroke gas engines and mounts as a 3 inch round instrument, matching the common gauge cutout size used across many helm and dash panels. It ships as a single gauge (Sierra model designation Tach 7K, Sterling 3 inch) and is covered under Sierra's customer satisfaction warranty, which protects against defects in workmanship and materials for the useful life of the product.
