What power do you currently have on the boat?
Qualitively, How do you feel that it performs?
Quantitively, how does it currently perform - top speed - cruise speed?
What are your minimum requirements - top end - cruise speed?
How do you use your boat - fishing - water sports - pleasure cruising - etc...?

What year is your 20-Outrage?
While I've heard great things about the Suzuki 140 4 stroke, I think I would want more power. Something like a 175 or 200 depending on the model year of your boat and the maximum rated horsepower.
I read a while back where Suzuki said they planned on introducing larger 4 strokes at the Miami Boat Show (2/13-2/18).

I think a stretched 140 HP would not be enough for the boat. Determine your optimum desireable cruising speed, then find an engine that will give that speed around 3500RPM. Putting 130-140HP on it will be like driving around in second gear. In that power range, the V-6 Mercury 135 Opti would be your fastest choice.
If you want to keep HP at a minimum, I would think that a good strong conventional V-6 150HP, such as Mercury EFI and Johnson carbed, would be adequate. My experience has been that the Yamaha 150 is not quite as powerful, although highly reliable.
My choice would be 200HP EFI or DFI.

A 175 JOHNSON carb 60 degree v6 oceanrunner would be great. If I had a 20' that is what I would look for. I have a 150 similar on my 18'.
