I've seen a Torqueedo in the harbor. We're not a good indicator here in Rockport, there are more hard dinghys than inflatables, and the majority of those are oar powered. But I would think anyone considering a new outboard will be looking at these. That is if the LP lugging, finding, etc isn't much difference.
As I often see outboard gas tanks awash in rain filled dinghys, this could be a better enviro. option? Fuel safety storage on boats, well,... big "kaboom" either way.
