Swapping motors

So I have a 7.4l gen6 that has a cracked blocked!

I found a 7.4l gen 6 MPi fuel injected drop in ready for a really good deal. Am I able to drop this motor into my boat without having to do anything? Like is there and ecm on the engine and a electric fuel pump on engine also?

I went to a 350 Mag MPI and it was plug and play. ECM is on the engine. Merc has a pretty sweet system.

Just check the pin counts on the harnesses. Teague is very knowledgeable on the adaptors if you need one.
