ECM MEFI-4 Broken

[Andreasmartet]

Hello Guys ,

I have been having problems with my boat for 2 months, it has only ever run only on 4 cylinders. It is a Tige 22V (2005).
After some testing and reading I have now sent the ECM to BOB (Obd Diagnstics) to check and he said exactly what I suspected. Injector driver B is not working (has no contact).

So now to my Question:
Does anyone know or know anyone where i can get an ECM Mefi-4 ? Obd Diagnostic has one in stock but it costs 3500$ and seems a bit expensive to me.
Or is the price range ok for an ECM?

It can also be a used one.

Thanks for your help,

Check bakes, they had one posted for $1000. or take the risk on a used one on ebay that needs to be reflashed? I also would call marine engine depot, they told me they have one on the shelf but I didnt ask how much it was.
