Our Series 9500/9600 GPS Interface System combines a digital LCD Engine Hour Meter, Tachometer, Fuel Flowmeter, Fuel Totalizer and nautical Miles Per Gallon over the ground in a single 3-3/8" diameter instrument which fits the panel space of a standard tachometer.  The speed signal required to calculate the nMPG reading is obtained from GPS and Loran systems having a NMEA 0183 serial port output.

The direct display of nautical Miles Per Gallon over the ground gives the skipper a powerful new tool to set optimum fuel efficiency under all conditions and to determine precisely how far he can go with his remaining fuel.

Diesel Model Features

• Fits most diesel engines rated from 25 hp to 4300 hp.  Twin diesels require 9700/9800 twin-engine packages for GPS Interface.
