Okay, 2005 Bayliner BR185, she is running nice. Cruised for about 4.5 hours non stop on the 3.0L engine. I watch my gagues all the time, today I noticed this weird behavior. My tach was bouncing between 2000 to 4500 RPM without moving the throttle. My temperature gague never rose above 125 normal operation temp is 175 and finally my fuel bounced as I used fuel, like between Full and 3/4 to 1/2 and 3/4. Any ideas? Is it time to panic?

Re: I Will Not Panic, I Will Not Panic

your gauges must have a bad ground or power wire. Just look under the dash and feel for lose wires running between the gagues and or to the source of power or ground. could be a bad terninal or a lose wire on the buss or the wire from your key to the hot buss. I like to hook a known ground to the ground post on one of the gauges and see if that fixes it. if so just check all the grounds. If the jumper to ground does not fix it hook it to a known hot wire and hook it to the + side of any gauge.

In addition to checking the instrument panel wiring, check the connections at the battery, especially if it has wing nuts with no lock washers.

Wing nuts on batteries have caused more than a couple of headaches :(
I dont use them anymore --------------

UPDATE: Thanks for the suggestions, I did notice the ground wire on my ignition switch was conneted by a thread. I didn't have the gauge wired needed to replace it so it's off to the store tomorrow.
