Lets see if I can clear it up a little for you. Say you were running down the creek wide open with your 55 lb thrust MK. Also you happen to have an amp meter installed on it. At full speed the amp meter should be reading somewhere around 20 amps. All of a sudden you run into a plastic bag and the prop comes to a screeching halt. The amp meter is going to run up to 42 amps very fast. This is the stall current. Although the motor only draws 20 amps normally you still need a 50 amp fuse or breaker or else everythime you ran into some weeds you would blow it. You can calculate the stall amps if you know the resistance of the armature and apply ohm's law. Hope that makes sense.
