I want to increase the efficiency of my 55lb thrust trolling motor and increase the speed through the water, so I'm studying how people have used model airplane propellers on trolling motors. My understanding is that you can use a larger and therefore more efficient prop, with a larger pitch to achieve a higher boat speed at a lower RPM, if the motor has a PWM controller.
I'd also like to build a NACA foil around the shaft to increase efficiency at high speed. Without a foil, turbulents are visible near top speed.
I'm wondering if anyone has experimented with pulling/tractor props on a trolling motor? My motor (Haswing Osapian) has its shaft quite close to the prop end, so there is not enough room for the trailing edge of a foil between the shaft and prop. If it was pulling, then the shaft could be near the leading edge of the foil.
I don't want to spring for another trolling motor yet.
