What happened to Scott

Pleased to hear you made it home safe and sound! What a nerve racking experience.
 
lol@riveting ... I completely agree, I was stepping out of meetings at work to reply!!!!
 
Glad you are home Scott. I think things were getting weirded out with the lightning strike theories. Probably good to start a fresh thread to stay on task.
 
Good news, we made it back to Michigan City no worse for wear. I had to tape both alarm horns in electrical tape to make the constant beeping tolerable. (4 beeps every two minutes and of course they weren't synchronized)

The boat ran without a hiccup, so why the hell do we need IAC's in the first place? Now to figure out where to go from here.....

Glad you made it home.
Did you get things figured out? I spoke to a guy when I was out this weekend. He had a similar issue and possibly told me about a procedure that may work.
If interested I can tell you what he said.
 
He said:
1. Turn the batteries off
2. Disconnect the Forward ECM (inside of your port side manifold)
3. Disconnect the Aft one.
4. Wait 45 seconds
5. Reconnect the Forward one
6. Reconnect the Aft one.

Turn batteries back on and test. He said he learned this from the Service manager at Vancouver's MP Marine (Sea Ray Dealer). It fixed his issue. It somehow resets it? He has twin 350 MAG MPIs in his 320DA.
 
I don't want to give you the wrong info. Maybe the 350s have a different PCM. I'll maybe get a look and take some pics on my Cousin's boat to show you what I learned. Yours may be different.
