Thanks Ken. That's useful data.
I've burned out two 40A Chinese PWM controllers already. I finally sprung for a 100A rated controller, and that's fine at the usual 30A my motor draws.
My boat is a 6m (19.5') Pacific proa. The main hull is 6m long and 0.5m wide at the waterline. The ama (outrigger) is 4m long and 0.2m wide. So skinny and fast when sailing. It weighs about 200kg (450 lbs).
The Haswing trolling motor pushes it at maybe 3 knots, but based on the 30A current draw, I think it's not fully loaded. I think a 12x6 prop would provide a lot more speed. I can limit the current with the PWM, and I have a 40A breaker as well, so no more smoke.
I'd like to try a tractor prop. I wonder if that would cause undue mechanical stress on the motors bushings? With a spinner and a foil around the shaft tube, it would be have much less drag.
