DIGITAL TACHOMETER

A tachometer is essential for proper outboard performance.
The engine speed can be monitored to obtain most efficient operation.
In twin engine applications, the tachometers can be used to set the throttle of each engine accu-
rately.
The digital tachometer includes the elapsed hour meter, the trim meter and the oil warning indicator.
Also, this meter can be used for both 2 and 4 stroke models by switching the settings.
