I found a 200hp e-tec is it worth it?

I'm not sure if its the HO or not. I'm going to check it out this weekend and run a compression check. Although, I really don't like the idea of not being able to work on it my self. How much exactly is that software? Also, I only fish once a month and only travel a few miles so maybe a carbed motor will better suite me. The boat I'm running now is an 81 V20 with a V4 evinrude but I actually plan on putting this motor on my 78 and set it up to go out to the oil rigs and troll. It only has a 40 gallon gas tank from what I remember. Once its done, the 81 will be for sale.
