Wally - I sailed on a Morgan last Summer that had power winches on the head sail and they were nice! We used one to furl the sail as well when the winds were starting to make that a chore. BUT - they did seem to tax the batteries pretty hard during use So some healthy wiring might be in order. The head room needed can also be an issue in some boats - not sure about ours?
Defender seems to have a sale going on for the kits:

Good Luck

One disadvantage of power winches is that they will keep grinding if you get a minor jam turning it into a major jam if yur not really careful, particularly with furling mains. Do you really need powwer winches?

This is the Milwaukee Heavy Duty 1/2 inch Cordless Drill I use in place of a power winch. It is not as powerful as a power winch, but it gets the job done raising the main, furling in the jib and to some degree pulling in the jib sheets. It will not pull the sheets in all the way. I find I have to hand crank the sheets in when they start to have a heavy load.

The star shapped bit that fits into the winch is available at [url]www.info@winchbit.com[/url]

I paid $253.50 for the Milwaukee drill through Amazon and less than $50 for the bit about five years ago.

BUT be aware it is not a light item, hard to stow, and generates aLOT of torque, enough that you have to make sure that you brace yourself. It will work in both forward and reverse but you have to make sure that the hex screw that is in place with locktite or it WILL spin the bit off. all that being said it makes raising the main a breeze and i haven't found a problem with it bringing the jib in all the way, if it set for the second speed on the winch.. fwiw..
