I wouldn't put a motor in a well either - preferring to just clamp it somewhere easy to tilt the thing and preferably out of the way. Though I guess if one knew in advance that ventilation was going to be the main problem it would be merely a matter of designing the well for more air. Simple enough. I lean toward saving the fancy sculptured well-type effort for something that matters, maybe a cassette rudder.
 
Since boats are rigid - and with far less resistance when moving forward, then does it much matter where the motor pushes from? 
I'm thinking that it's the rare lucky outboard that gets mounted on the centerline and set up to thrust exactly fore and aft. 
 Our Fboat tri has the Yamaha 9.9 deepshaft 4 stroke. It's offset and that motor has an adjustment screw so it can be set up permanently with the thrust angled a few degrees one way or the other. It's my guess that outboards are made that way specifically for offcenter installations.
