[MHml] HP to Watts

[Dan Frenette]

A simple formula of 1 hp required = 746 Watts looks simple but do we 
really need that many watts to get the same effective power from an 
electric motor vs an outboard?

I know Johnson/Evenrude claim's they are measuring HP at the prop but 
what does that mean in terms of what we would need from an eletric motor 
to do the same thing?

Should I be looking at units of thrust from the prop or ???  I don't 
know if the thrust is commonly quoted??? An eletric motor has better 
torque characteristics if I understand what's going on under water.
