Mercury 225 EFI 2001

After running across the lake to our fishing spot, I pulled back on the throttle, but engine did not slow. dropped it back to neutral, but engine revved and did not idle down at all. Had to be towed back to landing. Motor will still crank, but only runs at a high RPM. Any one else encounter this or have an idea of what happened?

From reading forums I think my EFI ECM needs to be replaced. Looking for advice on these. New vs.used? Number on my sticker is 830046 12. What does the 12 refer to? I found some parts online, but ending in different numbers.
