At the dock I noticed trouble with letting down the lower unit the gauge was not moving smoothly (starting and stopping) after four or five attempts I finally got the trim down all the way. Circled several times to allow warm up - accelerated slowly and after about fifteen minutes opened her up to 45 mi. attempted to readjust the trim three times and the engine immediately spit and cut out -all the gauges would spike and go crazy before I could get off the trim switch. So I left the trim down and the engine ran great till I turned it off 30 minutes later. After fishing for about an hour I tried to restart the motor-and nothing happened, not even the warning tone when the key is engaged. No reaction from the gauges it was like there was no batteries connected. I checked the battery test switch (connected to my electric motor) and it read 14+ volts. After being towed back to the dock I replaced ALL the fuses ( except for the grey one in the main fuse box) and still now reaction - not even the radio plays! ANY (I mean ANY) ideas? No corrosion anywhere - engine only has 55 hours on it.
