Sierra 58935P Amega 3 Inch Systems Check Tachometer, 0-7000 RPM, for Johnson/Evinrude Engines

The Sierra 58935P is a 3 inch Amega Systems Check electric tachometer built for Johnson/Evinrude engines, covering a 0-7000 RPM range so you can monitor engine speed at a glance from the helm. The domed face design improves readability in bright sunlight and from an angle, making it easy to keep an eye on RPM while underway. Construction uses alloy steel and metal components engineered to hold up in a marine environment, where vibration, moisture, and temperature swings quickly wear out lower-quality gauges.

As part of Sierra's Amega Systems Check line, the 58935P is built to work as a direct panel gauge for Johnson/Evinrude engines, giving boat owners a reliable way to track engine performance without relying on an aftermarket or non-marine-rated tachometer. Every Sierra part, including this tachometer, is backed by Sierra's customer satisfaction warranty, reflecting the company's 50 years in the marine parts industry.
