Re: sab motor with varable pitch prop

Variable props have long been standard on aircraft, so there's reason to think the concept works. I suspect the reason it is shunned on boats, is that putting more moving parts in a corrosive salt water bath and relying on seals...We should all be cringing by now, right? (G)
I'd like an exotic sports car, too. But not the maintenance bill I know it will require. A cheap bulky gearbox, a solid shaft, no bearings, no seals...This is why Detroit products could be fixed with a screwdriver and plier, while German ones required specialized tools.
