The conversion is 1 KW = 1.34 HP so the 5 KW Motor = 6.7 HP
The 5KW motor/mounting bracket/controller/reducer weigh 58.5 lbs
The motor/controller requires 48 volt batteries.
The battery modules I use are 12.8 volts x 100 AH each and weigh 29 lbs.
Tell me more about your boat, engine, propeller shaft speed and the existing saildrive.
