[Electric Boats] 220 ac to 180 dc controller to 3 hp Leeson sea trial

 

  Black magic does work.   My 34 foot  9 ton CHB sea trial results .   The electric motor turns my shaft with a 5/8 belt   .    Pulley on the motor is 2.5 inch and on the shaft is 9 inch .    Power  :  240 volts comes from my generator. 


       Fishing speed can go all day ( 45 % throttle puts me at fishing speed ) .     

   Just shy of 4mph at full tilt .   At full throttle the controller heated up after 15 min to plastic smelling levels.  

So I back off and be happy , also thinking of going 6:1 ish instead of  4:1

Havent had a silent running off batteries because I don't have an inverter.    So im thinking what to do next.      

     

     Sure wish I knew which is a better way to go in the long run.    People are worried about my electrolysis. 

         Very happy , I credit this group Thank You all. 

Ps your original recommendation of 6:1 appears right on  . You da man !!!!


      Yesterday someone at the dock just about gave me a golf cart motor.    model 5BC48Jb247    36 volt.  ?
