MERCURY 350 MAG MPI IAC VALVE REPLACEMENT (2 BEEPS & STALLING SOLVED & FIXED)

My Donzi 28ZX is equipped with twin mercury 350 mag mpi engines. The boat routinely has it services done and the engine were just previously rebuilt last season (2021) The engines have around 340hrs on them. All the gauges work as they should and no problems occurred.
The other day I took my boat out on a quick run and this beep came on. It beeped twice every minute or two and would not stop. I noticed that the starboard engine was stalling when in neutral or at a very low RPM. I did some hunting and came to the conclusion that it was the IAC valve (Idle Air Control Valve)
I went to my local marine store and they had the part in stock. I replaced the IAC valve and the engine beeping along with the stalling went away. The problem was fixed.
Hope this helps. If you have any questions, leave a comment. Thanks

Appreciate it. I believe we have the same boat. I've got a 2005. I put a closed cooling system on mine.

That’s awesome. I love this boat. I’m actually thinking about selling it. What is the closed cooling system and how does it work?

Replace crank shaft sencer and turn distributor just a little to advance and check spark plugs and clean distributor cap inside at the points and rotor and happy boating

Great video thank you! Had the beeping start last weekend. Also noticed I had to throttle up a little on that engine to get it to start so I’ll replace this valve and see if that does the trick. Quite a price difference between the IAC from Wesr Marine ($148) and Amazon ($27). Where did you get yours?

Thank you. Sorry for the late reply. I’m glad that the video helped. I got mine at a local Marine supplier. They had the part at the store. I don’t remember what I paid

Where did you get your part from? And are you able to share the part number?

@amendolarestudios 10 ай бұрын

I got the part at my local marine supplier. The place is called Fred Chall marine supply. It’s in Freeport, Long Island. I don’t have the part number offhand, but if you call them, they’ll be able to tell you over the phone.

Does your engine hunt back and forth on a cold start for the first 10 seconds or so before smoothing out? Wonder if my iac is getting lazy

It did a little bit. Now it’s good. Make sure your batteries are good and charged as well.

@amendolarestudios5276 well I mean mine has always done it really since it was brand new

I was told it was normal and it just takes it a few seconds to figure out what the air temp is and such and it runs off the map values of the last time it was ran.
