I saw the video of electric bike you posted but I don’t think the boat propeller will unload that much as the boat speed up from 3 to 6 knots...

on fishing boats they put "trolling valves" on the transmission to reduce pressure and lower the temperature

if i go out fishing at a slow speed without the switch, what does that do to the electric motors temperature and efficiency?

i dont know, im asking
heres a good video of another person showing the switching back and forth, somethings going on with torque. why switch back to wye unless theres no torque down low in delta

i went youtubing to figure this out and found, the engineering mindset
heres their article, i got the pics from

wye/star
does the tripling of amps in delta triple the torque on the shaft?
