My biggest concern with non-fixed prop, is that it will decide to stop
feathering, requires more maintenance, and will require a haul-out if it
Having owned Max Props for over 20 years without any failures I think that is an unrealistic fear. Yes they require some maintenance but what on a boat does not.. you still have to zinc and clean a fixed prop Max Prop is the same only additional maintenance is a lube once every 18-24 months. I have done that in the water as well no biggie.
