Truly innovative on many levels, this product could be a game-changer, https://speedonthewater.com/new-boat-hidden/4996-kiekhaefer-awarded-patent-on-new-variable-propeller-pitch-surface-drive.

I remember seeing another product similar to this on a military application a few years back.

anyone else see that?

Will it be offered in different ratios, possibly an overdrive? The diesels we've tested all seem to need an overdrive to meet the typical propeller RPM needed in offshore performance boats.

I do not remember the military drive with variable pitch.

I had a Land and Sea Torque Shift prop once. Does that count?
