The Aldi winch I picked up, cheap, had water in the gearbox. After spending quite some time cleaning and regreasing it, I have added an extra O ring to the clutch handle, and have used silicon to make seals for the cable drum. I used an electrical Junction box which seals properly, for the control box. when all of it has dried for a few days, I will put it in a big container of water and run it. Fingers crossed.
