Sierra 68391P Eclipse 2 Inch Hour Meter, 12-24 VDC, 10,000 Hour Range

The Sierra 68391P is a 2 inch Eclipse series hour meter that tracks total engine running hours on a black dial background with smart white and blue graphics. It is designed for boaters and technicians who need an accurate, easy-to-read record of engine run time for maintenance scheduling and resale documentation. The dial reads up to a 10,000 hour range and displays both U.S. And metric scales with ISO symbols where appropriate, making it suitable for a wide range of gauge panel setups.

The gauge uses a scratch-resistant domed glass lens that sheds water and resists abrasion, paired with a very low profile bezel that follows the curve of the lens to eliminate water trapping around the rim. Perimeter lighting around the dial face improves readability at night or in low-light engine compartments. The 68391P operates on 12-24 VDC and is part of Sierra's Eclipse gauge lineup, which offers matching trim gauges sold separately. This hour meter is not designed for diesel applications.
