Default RE: Electric boat prop sizing


ORIGINAL: pilotj

Thanks for feedback, makes sense.

What do you suggest is a optimal RPM for a prop that is 2-4" diameter?

Thanks
Power = a constant x RPM x Prop load so to answer your question you could give us an idea of the size/shape and speed of the boat and a power figure could be arrived at.

150-200 Watts is a lot of power for a boat
