I am trying to figure out the engine that this ECu / EMS was originaly used on. It is on my ski boat engine (351W multiport fuel injection).

Here are the numbers off the box.

EFI-MA39 300M EEC-IV

F4FF-12A650-LE *HYND313KVL5Q* G NPF 0D191

I am looking at the AEM Plug and Play system to replace it with, to determine the correct one, I need to crack the code on this ECU.

Thanks
Dallas

Check out Gt40marine.com. I had the same problem as you and couldn’t find one anywhere. They got me back on the water with a new ecu for my boat
