Saw that too. Rationale for no pricing is that each prop is custom designed for each vessel. And they are targeting a huge range of boat sizes, 30-300 feet.Got this via Boattest today: https://sharrowbyveem.com. Apparently a partnership to make the inboard props Sharrow has never managed to get to production. Website is completely evasive about ultimate availability and pricing. But, I did do the preorder, $100 fully refundable, so what the heck. If they come out with a reasonably priced prop next year or later, maybe I'll get some.
any way you cut it the prop is going to be many boat bucks. I‘m intrigued but not ready to plunk down for a new prop yet.
