1998 Mercruiser 502 Mag MPI
Last weekend I was motoring out of the cove I launch at and as I accelerated the engine just died. It was just like I had pulled the lanyard kill switch. I fiddled around with the kill switch and the circuit breaker on the ECU (???) for a while and after about 10 minutes she fired up. It would crank over just fine but wouldn't fire. When turning the key to the on position the "alarm" buzzer wouldn't sound.
Today the same thing happened. After running about 10 miles at 3200 RPMs she just died. No "alarm" when turning the key on. While getting a tow and continuing to fiddle with the circuit breaker, shifter lever, kill switch, the alarm sounded and she fired up. Dropped the tow line and started toward home. Half mile later running at 4000 RPM she died again and I could never get it to start again. Tow again.
So what is my problem?
Remember the bolt I posted about last week that I couldn't find a spot for? Related or coincidence?
