Sierra 68408P Eclipse 2 Inch Voltmeter, 8-18 VDC, Universal Fit for Outboards, Stern Drives and Gasoline Inboards

The Sierra 68408P Eclipse Voltmeter is a 2 inch, 8-18 VDC gauge designed to monitor battery and charging system voltage aboard outboard, stern drive, and gasoline-powered inboard boats. Part of the Sierra Eclipse instrument line, it features smart white and blue graphics on a black dial background paired with a very low profile bezel that follows the curve of the lens, eliminating water trapping around the gauge face. The domed glass lens is scratch-resistant and sheds water, keeping the dial readable in wet marine conditions, while integrated perimeter lighting provides excellent readability at night or in low-light helm stations.

The dial is marked with both U.S. And metric scales, including ISO symbols where appropriate, so it reads clearly across different instrument panel setups. It requires no separate sender, making installation straightforward as a direct voltage monitor. As a universal-fit gauge, the 68408P is suited to most outboards, stern drives, and gasoline inboards, and optional add-on eyebrow or square bezels are available separately for boaters who want a different bezel treatment.
