Your priorities are all messed up!

First your engine is an EFI not MPI. Do you have a spare IAC(Idle Air Controller)? It's a common part to fail and cause symptoms similar to yours when it died at idle. Cutting out at 25 mph though is what is strange. Was it running perfectly until then?
How are your batteries?...and their connections?
Check all of your connections, including a close inspection of the alternator's connections? I had similar issues with my 230OV (5.7EFI) when a poor connection from my alternator was bad. I repaired that with a new terminal connector and replaced my batteries and she ran like a top after that.
IAC is part #7

I wish that were true. Unfortunately, if I don't work, there will be no boat to need fixing. :smt009
According to this, it is an MPI:

yes, it was running perfectly until it died.
Batteries are both brand new this year. It cranks over beautifully.
He may have been referring to the discrepancy between your forum boat information, which says MPI, and the picture you posted which is of a 5.0L EFI engine.
yeah, the engine pic I posted was one I found on Google-Images, not my actual engine. I didn't notice that it was an EFI engine pic, instead of an MPI.
From what I know, you are BOTH right.
EFI or "electronic fuel injection" applies as does MPI or "multi point injection, where there is a separate injector for each cylinder.
Some older post carb models were EFI, but used one big fuel injector where the carb would normally be to provide fuel mist for the intakes. Not as precise as having an injector providing precise fuel directly to an individual cylinder.

What about Boat US or SeaTow for your towing?
