Hangkai have been about a while making 2-4 hp outboards. Looks like they have now made a 12 hp.
Given the issues around weight to power you have to wonder if this would be any good for Sibbers and if Hangkai are improveing.
I am of course aware of the legal issues around 2 strokes so for the purposes of this thread perhaps we should all assume that this would be for commercial use
