I would do a Honda GX 200 (6.5 HP) racing go cart motor with a TAV: if you need more power later you can always take off the governor, or do the first stage racing mod to get 9 HP out of the motor..
Gearing with 12 tooth TAV or 12 tooth clutch: 56 tooth #41 chain
You can find a lot of great information on building a winch at
www.wakeboarding-winch.com
1. 6.5 HP motor probably around 300 USD
2. Torq-a-verter brand CVT cover and transmission... around 180 USD
3. sprocket: you can use anywhere from 56 to 72 tooth sprocket with a 4 to 8 inch spool... about 30 USD
4. #41 Chain approx 15 USD
5. Belt for the CVT comes with #2
6. hitch pin for transporting winch using the hitch of a car
7. pillow block bearings, holds shaft onto the frame... approx 30 USD
8. Gocart axle... 30 in long, cut to fit your frame... approx 30 USD
9. ibolt can be used for rope guidance 2 USD
10. Fairlead rollers for rope guidance onto the spool 10 USD
Then you can can customize everything else all you want... Here are pics of our winch:
