The actual drive in all outboards is direct shaft to the gearbox. I think when referring to belt or chain you are only talking about driving the camshaft as in the late model 4 strokes. 2 strokes are simpler and just have reed valves. I would think that unless you are going for a more expensive late model outfit that most boats you would see that meet your requirements will be 2 strokes.
