I just got back from the lake. After motoring at WOT for a couple of miles, we stopped to eat our dinner. I went to turn on the depth finder, and noticed that it wouldn't turn on - also, the radio would turn on, then turn off immediately. I tried to start the engine, and it would fire and run for a second, but it would bog down and stall, even if I gave it throttle. Also, during this time the tach started to creep up - it went from 1,000 to 4,000 even though the engine wasn't running.<br /><br />I waited about a half hour, and tried to start it again. This time it started, although the tach was at 2,000 throughout the whole throttle range. For kicks, I tried the fishfinder again, and it turned on. The voltmeter in the fishfinder was registering 14.4 volts with the engine running. If I turned on another electrical accessory (radio, light, etc.) it would drop to 13.4. With the engine off, the battery is at 12.4<br /><br />The tach started working again, and I ran the boat another hour or so. Any idea what my problem could be? I hate intermittent problems like this, it doesn't give me a whole lot of confidence in my ability to get back to the ramp.<br /><br />Thanks for the help.<br /><br />KB
