2001 Ficht Ram v4 75Hp correct replacement EMM

[dstanden]

Hi everyone, I purchased a 2001 Evinrude Ficht Ram very cheap knowing it had a blown 586518 EMM. Fault # 37 then series of 8's fatality. No ignition. I've been hunting around for a replacement on e-bay and reading a lot of forum posts and seem to be getting conflicting information. The DFI technologies website shows 586484 as a possible upgrade/ replacement but most I've seen are all off v6's. I've also seen 586724 EMM's for sale starting they will work on the 2001 V4's. I do have a registered copy of EVdiag and can perform an EMM replacement.
Question 1: would the newer model 586724 EMM's be more reliable then replacing my EMM with an original 586518?
Question 2: Can the 586724 be used on a 2001 V4?
There seem to be a lot more 586724's available out there and a bit cheaper than the 586518's.
I spoke with MarineComputerSupply and he told me the series of 8's was not repairable and he didn't currently have another 586518 as a core to repair for me. That's why I'm hunting down different options.
Any advise would be greatly appreciated and thanks to everyone in advance.

This difference is the injectors as they changed in later 2001/02 and they added exhaust pressure sensor. The OEM number does not cross reference over
