I have a friend with a 2004 SeaRay 22'. It has a 5.7 with a Bravo outdrive. Yesterday he was cruising down the river the he heard 2 beeps then a 2 minute pause then 2 beeps again. When he put it in neutral, it ran rough. He got it to go again but then same thing. This time when he shifter it in neutral it stalled and would not let him start it with the shifter in the lock (center) position. When he shifter it in the neutral position (button press in, not on gear) it will start until return to center position. Would any one know what the beeps mean? The book says they are stored in ECM's memory and it has to be read with a diagnostic tool. Thanks for your help on this.
 
There is something along the lines of 25 different faults that could result in the 2 beeps/minute. You need the diagnostic tool to read the fault to tell you exactly what it is.
 
Yes, you need the diagnostic computer/tool to check the codes. That said, the short beeps and the failure to start probably indicates a bad IAC valve, a common problem, easily fixed. But, don't just throw money and parts at the problem; have a diagnostic run. Hy

+1 on the IAC (Idle Air Control valve). Just had mine replaced on my starboard MerCruiser 6.2L engine. I had the same two beeps, about every minute or so. The marina determined the fault with the diagnostic tool.

I carry a spare IAC, this problem is not rare. They are easy to change in the wild. Probably need to get a mechanic to put the computer on the new on to make sure everything is in tune and to knock out the old code.
 
He took it to a Marina to have tested. I will let you know the out come. Thanks for your help.
 
<< Uh oh. It's beeping. Only 5 seconds to cut the red wire. NO. The blue wire. I think. Maybe. Was it the green w/ black stripe... >>

Yellow wire, yellow wire!

Here a some of the trips for 2 beep Merc fault warning alerts, but note these are apparently 2 beeps/ 1 min. & you'd need diagnostic scanning to narrow down the possiblities:
