    Very impressive.....hopefully someone gets a cost answer. Pretty easy to extrapolate the value from there.

    Very interesting. Whether this plays out for the recreational market or not, who knows. But at the very least, it's nice to see some thought going into a different way of doing things. I remember, quite a while ago, there was some kind of prop where the blades changed their angle as the RPM's changed? Sort of like shifting gears in a car. But there were issues with it. I don't recall much else, though.

    Another thought... and this is not to take away from the product, just wondering outloud... right now, there is a very well established network of prop shops that can fix damaged props. What would happen in this case? Sent back to manufacturer? Just have to buy a new one? These would obviously be more difficult to repair and would require a prop shop to make a sizable investment into the tooling (if even possible).

    Bad connection today and video keeps breaking up. Does it say anything about performance in reverse?

    Pretty exciting advancements to the old screw.

    They would have to be really competitively priced in order to get a foothold in the recreational market.
    They’d also probably have to develop a wide network of dealers with good stock available to replace damaged props on recreational boats.

    I agree with JVM, and all of those things he mentioned take time to get set up. He'd also have to create a large manufacturing facility just to get some props out there for boaters to buy.

    Just to clarify, I have no interest in buying a new set of props. After our summer long trip to Canada we'll be selling Beachcomber and buying a motor home of some sort.

    Makes no sense at this point to drop ~10 boat bucks on props I'd probably never use.

    Very interesting to see what it would do on my 340 with v drives. The only test they have advertised was on a small outboard boat... They talk about freighters and large ocean type boats. Just wondering if small and light boats or slow and heavy might be a sweet spot for them. I sent in an inquiry regarding my boat. Will be interesting to see.

    It is a very interesting design. It reads like an aluminium 3D Lazer printed, which I suspect is disposable after a strike......but if the numbers are right, you keep a spares and buy new.......

    Interesting data to say the least.
    As mentioned in earlier posts, I too think that the price point may be prohibitive to the large majority of recreational boaters. I for one am not overly concerned with fuel burn & top speed. I would like a slower plane speed, but am not willing to spend a fortune to get it. I suspect that that is representitive of a lot of "recreational boaters".

    Some real good points above on choice in the recreational industry.
    If the prop does give better performance but costs a lot more, it would probably only affect new boat sales due to cost-benefit for existing boats.
    Then, the prop selection would be similar to buying a new Chevy truck today: the 5.3L or the 6.2L? Certainly the 6.2 is a beast in performance, but initial cost and long term economy keep many of us rooted.
    I can see where offshore fisherman needing speed and unlikely to hit a log may choose a prop like that, even if it costs a thousand more.
    I run rescue boats in the MS River. While I need speed, I need a prop that can hit logs and other debris and still make it to my destination. Saving a little fuel or planing a few seconds quicker are not my primary concern. Unless these props are stronger than a 4-blade SS, we will not be changing to these new props with my organization.
