I have 2000 MerCruiser 350 MAG MPI in my Crownline. It has been a great boat so far except just this week we had to get towed in twice. Anyways both times same thing, we unload just fine, run around for about a half hour, then sit for an hour, then run around for another half hour, then sit for another hour. Then go to start it up and I get 3 or 4 beeps after it turns over then the engine dies. I thought maybe it was a bad fuel gauge (even though it read half full) so I put 20 more gallons in it, put the ear muffs on and it started right up and ran fine for 10-15 min.
Symptoms:
Boat starts up fine and will run for a while.
3-4 beeps at idle then shuts off.
1st attempt to restart and it will idle for 10-15 seconds. When you put the throttle into neutral and give it some gas you can hear it back firing or feeding back. (no beeps)
Repeat attempts to start it and it won't run for more than a couple seconds. (no beeps)
You can hear the fuel pump kicking in so I don't think its that.
All fluid levels are full.
Temp runs 130-150.
Kill switch is not engaged.
I have done some reading and I am not getting the 2 beeps every minute. I have read that it could be a bad sensor, maybe IAC or the IAC valve muffler is clogged, maybe timing?.?...
Anyways I'll most likely be taking it into the shop for a look here shortly but I wanted to see if I am missing anything.
Thanks much in advance.
Tony
