Are you sure you're not mixing units? 500 Watts would be very small for a golf car controller. 500 AMPS would be a pretty big one.
Some basics:
Amps x Volts = Watts
1 HP = 746 Watts

A high rating golf cart controller maxes out at somewhere around 500 watts for carts that go perhaps in the high 20 MPH range. I would think that it takes less power to move a sailboat at hull speed than to push a golf cart around at 27 MPH...
