The 8 Best Marine Hour meters (2023 reviews)

This hour meter is powered by the pulsation coming from the spark plug wire. It simply connects to the meter and wraps around the ignition wire. The meter counts the number of time Spark plugs fire. It will show an hoursglass figure that flashes when it is reading an RPM signal.

The Hour Meter picks up an induction field from the spark plug wire. It does not display rpm while running as a tachometer would, but it only displays hours accumulated. This is a quick easy installation of about 5 minutes and is highly recommended. It is no clicking like mechanical meters. These make life a breeze and as an important note they DO NOT require batteries.
