Sergio,
Do a little research...
Check your cost of replacement parts, like water pumps, prop shafts, things
that break on a motor. You'll be quite suprised.
Your dealer is giving you a straight story, the EFI is much preferred over a
carb engine.

Now, if he didn't tell you, the Mercury 4-stroke is built by Yamaha. Why
don't you just go to the original source and get a Yamaha?
