My guess is that the belt is certain to be the weak link in that system. He could do a serious lightening job on that and still be quite solid. Good re-sourcing of original materials.

I think the guy who made this knew what he was doing. I'd like to know the weight too. One thing is for sure, a belt drive has to have two sprockets, upper and lower shafts, prop flange and so on. They all weigh at least 40 lbs. I think weight could be saved back by incorporating the alternator in the drive similar to Briggs and Stratton, likewise the forward engine mounts.
