Merc 115HP ECM Part #

[Ruggybuggy]

Does anyone know the part number for a 2007 115HP EFI 4 stroke ECM and a good source to buy? All the parts diagrams have these two options

Mercury ECM, Engine Control Module - 115
Part# 89772721T

and

Mercury ECM, Engine Control Module - 115 EU
Part# 89772724T

Which one?? :facepalm:

And you will see that most of those parts manuals also specify what engine s/ns both of those p/ns are applicable to.
