I had one of these for 22 years and thought best to replace it when I purchsed a new winch. I own a 22 foot walk around cuddy cabin fiberglass boat and this pulley had done the job over the years faithfully.If used in salt water you need to keep it greased and sprayed with corrosion inhibitors. Very strong and dependable. Could not find it here in Miami most folks use float on trailers. ordered 2. Great product.
