Just a final report on this project - I went ahead and bought the Lewmar 30 ST EVO which is a real nice winch. When I got back home from Florida I found that space was not as big an issue as I thought and there was lots of room for the Lewmar 30. I also discovered there is no aluminum plate imbeded in the deck under the cabin top winches, just wood. All I had to do was remove the thin plywood liner which has about 8 screws, then remove the nuts, take off the winch, mark and drill new holes for the Lewmar, fill the old holes with 5200, then install the new winch with 5200 around all the bolt holes as well as under the heads of the countersunk bolts. That is one project put to bed.
