I have nothing working on my console. No gas gauge, no rpms, no aerator for livewell, no bilge pump. Checked the fuses, seem OK. Could it be a bad ground wire. My depth finder on the console works, which is hooked up to the wire board under the console.Please any suggestions on what to look for. I am not an electrician, and am stumped!!

If you haven't checked, check at battery for a fuse in main power lead. Do you have a main power switch for dash? Check all your connections for loose wire. I would say if finder is working and wired to board you are losing power between that board and dash. Hope this helps some.
If your starter isn't working either check the fuse under the cowling. They are usually a 20 amp.
My motor is an 81 Merc inline 6 115hp. Starter is working. I will check under console for loose wires. No fuse at the battery. It does have a power switch on console for everything. There may be a loose or disconnected wire there. I will check tonite and get back tomorrow.
The ground wire is good. I have power under the dash/console, 12.7 volts to my main wire board. I did see a white connector of wires. I did not see there was a problem, but there could be. I will take this apart and see if there are loose wires or connections there. My "Master" power switch may be bad too. I ran out of daylight last nite. I am going to pull my 4 switch board off the console tonight and check voltage on wiring going in and the switches: Master power, lights, livewell aerator, bilge plus no gas gauge, voltage, rpms, etc. I have got to figure this out!! My depthfinder works that is connected directly to the board, which it should, I have 12.7 volts there. I believe if I can find why the master power switch isn't working, fix it, then the rest of my instruments/console should work too. Checked the voltage on wires going into the Master switch, nothing. Not sure where to turn now. Any suggestions?

First thing I would do is try to trace the wires from master Back to it's power source. You have to have a loose connection or blown fuse in that wiring.
If you have a fuse panel under the dash, spin each fuse in it's holder, if there is any corrosion nothing will work, if things start working, spray battery terminal cleaner on fuse panel. If you have power under the dash at the fuse panel, and nothing to the power switch, trace the wire back , I have seen factory plugs with 8-10 wires in them get corroded and cause all kinds of problems, and if nothing else run a new wire from the fuse panel to the switch and see what happens
