Could I use a small outboard on the Eastport Pram? If so, what size?

A 2HP outboard has been demonstrated to work well. The Eastport Pram's transom and structure is configured for a small outboard right out of the box. It's a very small boat, of course, and shouldn't be confused with a Boston Whaler. The boat rows so well that I find it hard to imagine why an internal combustion engine is needed for anything except a very long and regular commute across a windy harbor.
