The prop has an optimum speed and the motor has an optimum speed. Proper ratio in the gear reduction is when they match. My initial installation at 2.5 to 1 was over propped and I could “overload” the motor. At 3 to 1 it drives the boat much like the old 30hp Volvo only more controllable.
I noticed no significant change in the noise
level with my ratio changes.
Thunderstruck advises to not use direct drive without some sort of thrust bearing to save the electric motor bearings from the thrust loads.
