On my previous boat, Freedom 36 I used an 18 volt drill and winchbit to raise the sails.
I since got a Freedom 40/40 with a much larger main. The boat has a Harken 48ST with electric conversion. The gears seem to have gone, and the motor spins but does not turn the winch. I am going to take the gearbox apart and see if it can be repaired, but if repair is not possible, would one of the large 28 volt Milwaukee right angle drills with the winchbit work with this large a sail?
Harken is not supporting this older winch/electric conversion, so parts might not be available. Just thinking ahead if there is a substitute for going for a replacement. I just went over the winch itself, and it is fine.
