Hi Folks -
Relatively new and doing my absolute best to read, read, read… lots to digest.
My use case is not specific to an e-foil but rather a larger hull (small boat (kayak), ~13ft, 120lb hull) which I plan to use two hydrofoils on (center and rear) to provide a more economical and high speed method of point A to point B. There is a similar commercial product for sailboats of roughly the same profile called Foilsz, so I believe it’s a feasible goal.
I am looking at an MTI85165 which I believe will provide the required power / speed for liftoff relative to the increased drag and weight of the hull versus the more commonly used 6516X.
I’ve run into many motors with a “keyway” shaft, and that’s the only version the 85165 (no sensor) that Maytech has in stock. However, I haven’t been able to find any useful information about the practicality of a keyway shaft or how to mate it with a propeller. In fact, what I have been able to find on this forum seems to indicate “always screw”. Is there a real world way to mate a keyway shaft with any commercially available propellers?
Maytech doesn’t seem to have any interest in building more screw shafts of the 85165 for less than a 10 MOQ, because “customer has feedback before that wants keyways shaft”… so what’s the point of a keyway shaft?
