Electric wake winch help

Hi guys

Im really keen on using a second hand electric dc motor from a golf cart to drive a wake winch, however I am unsure of the specs needed etc for power required for a wake winch.

Please could anyone offer some advice as to what size dc motor would do the job and how to control the motor?

I know there are quite a few awesome electric inventions, but not give specifications on what motor was used and how to control the motor.


Regards

David
