Boat Motor Fuel Management System Gauge

[JohnnyG]

The motor on my boat is a 1988 Mercury Black Max 150hp XR2. Are their any after market digital fuel management systems/gauges that will work on an older motor like mine? I would like it to digitally read gph and to show how many gallons of fuel remaining in the tank. This way I can save some money and get more miles without worrying about getting stranded lol.

Good question, I have the exact same year motor and that would be nice to have.

There may be a system out there but I don't think it would be cost effective. Sounds like you'd have to have a tank sensor, inline fuel flow sensor, and a gps puck that are all nmea 2000 compatible so you can tie them into the network then link the network to a compatible graph or n2k display like a lmf-200.
