Sierra 68400P Eclipse 3 Inch Tachometer and Hourmeter, 0-7000 RPM, Gas Engine

The Sierra 68400P is an Eclipse series tachometer and hourmeter combination gauge for gasoline-powered marine engines, with a 0-7000 RPM dial range and a 3 inch diameter. It is designed for most outboards, stern drives, and gasoline-powered inboards. The Eclipse design features smart white and blue graphics on a black dial background with a very low profile bezel that follows the curve of the lens, eliminating water trapping. The lens is domed glass that resists scratching while shedding water, and perimeter lighting keeps the dial readable at night. The dial is marked with both U.S. And metric scales, with ISO symbols where appropriate, so it reads clearly regardless of engine spec standard. Connection is made through a 1/8-27 NPT thread fitting. This gauge is part of Sierra's Eclipse instrument line, and optional add-on eyebrow or square bezels are available separately for buyers who want a different mounting look. Every Sierra gauge is built to meet or exceed the original equipment part it replaces and is engineered to withstand the marine environment.
