Has everyone seen these things?!

if I could get double the MPG at my 42 MPH cruise, that would be very cool. Less vibration would be great too!

I think around $1k/each I'd sign up, but not so much at the current price... but I do love the idea and tech.

They’ve yet to throw a 4 or 5 blade standard prop on when testing. Like to see one compared to something other than a cheap 3 blade.

You are correct - I run 4 blade currently, and would like to see a more 1:1 comparison. But the under water video looks great, a lot less water disturbance should mean more efficiency.

perfect prop in a unperfect boating world. Do they come with a lifetime warranty? seem too high tech for us?

Do they make it in cleaver form 26 spline shaft?!

Those things are all over the forums since last year. Bought and paid for BOAT TEST .com did a couple test and just watching them you can see there not on the level
