There were both carb and efi FF’s. Probably some efi EE’s out there too. Mercury did a lot of putting together whatever they had at the time, so when you think you’ve seen it all.....think again.

They will handle differently. The EE will have more low end punch where as the FF will have a higher top end.

Both were EFI or carb from the factory.

If you look in the divider plate area (exhaust chest) you will see the difference.
