I purchased a used boat with twin 115hp's that has the Yamaha Fuel Management System. Unfortunately, there wasn't a user's guide or manual with the FMS. I found a post on how to calibrate it, but, I can't seem to find any instructions on how to operate it. Can anyone help?
About the only thing you can do is reset it to zero when you fill up the gas tank. To do that just turn the ignition key to the "ON" position, do not start the motor, then push the two buttons down together for a few seconds. You'll see the totalizer reset to zero. Other than that just cycle through the MODE button to pull up whatever's available. If its not connected to your GPS or Speedometer output you won't see any other info other than gallons per hour and total fuel burned since reset.

I need the wire color codes for the S type plug out the back of the FM gauge. I have the harness that plugs into the plug. It looks like red, black and white. That happens to be the same colors as my pigtail harness out of my Humminbird 1157c I am connecting it too. Help!
